Quantum teleportation through time-shifted AdS wormholes

Abstract Based on the work of Gao-Jafferis-Wall and Maldacena-Stanford-Yang, we observe that the time-shifted thermofield states of two entangled CFTs can be made traversable by an appropriate coupling of the two CFTs, or alternatively by the application of a modified quantum teleportation protocol. This provides evidence for the smoothness of the horizon for a large class of...

Vertex operator algebras, Higgs branches, and modular differential equations

Abstract Every four-dimensional \( \mathcal{N}=2 \) superconformal field theory comes equipped with an intricate algebraic invariant, the associated vertex operator algebra. The relationships between this invariant and more conventional protected quantities in the same theories have yet to be completely understood. In this work, we aim to characterize the connection between the...

Renormalization group properties in the conformal sector: towards perturbatively renormalizable quantum gravity

Abstract The Wilsonian renormalization group (RG) requires Euclidean signature. The conformal factor of the metric then has a wrong-sign kinetic term, which has a profound effect on its RG properties. Generically for the conformal sector, complete flows exist only in the reverse direction (i.e. from the infrared to the ultraviolet). The Gaussian fixed point supports infinite...

Curious aspects of three-dimensional \( \mathcal{N}=1 \) SCFTs

Abstract We study the dynamics of certain 3d \( \mathcal{N}=1 \) time reversal invariant theories. Such theories often have exact moduli spaces of supersymmetric vacua. We propose several dualities and we test these proposals by comparing the deformations and supersymmetric ground states. First, we consider a theory where time reversal symmetry is only emergent in the infrared...

Magnetically-charged supersymmetric flows of gauged \( \mathcal{N}=8 \) supergravity in five dimensions

Abstract We study magnetically-charged supersymmetric flow equations in a consistent truncation of gauged \( \mathcal{N}=8 \) supergravity in five dimensions. This truncation gives gauged \( \mathcal{N}=2 \) supergravity coupled to two vector multiplets and two hypermultiplets. We derive magnetically-charged flow equations of scalar fields from vector and hypermultiplets. It...

Flat holography and Carrollian fluids

Abstract We show that a holographic description of four-dimensional asymptotically locally flat spacetimes is reached smoothly from the zero-cosmological-constant limit of anti-de Sitter holography. To this end, we use the derivative expansion of fluid/gravity correspondence. From the boundary perspective, the vanishing of the bulk cosmological constant appears as the zero...

One-loop quantization of rigid spinning strings in AdS3 × S3 × T 4 with mixed flux

Abstract We compute the one-loop correction to the classical dispersion relation of rigid closed spinning strings with two equal angular momenta in the AdS3 × S3 × T 4 background supported with a mixture of R-R and NS-NS three-form fluxes. This analysis is extended to the case of two arbitrary angular momenta in the pure NS-NS limit. We perform this computation by means of two...

Moduli anomalies and local terms in the operator product expansion

Abstract Local terms in the Operator Product Expansion in Superconformal Theories with extended supersymmetry are identified. Assuming a factorized structure for these terms their contributions are discussed.

Mean field quantization of effective string

Abstract I describe the recently proposed quantization of bosonic string about the meanfield ground state, paying special attention to the differences from the usual quantization about the classical vacuum which turns out to be unstable for d > 2. In particular, the string susceptibility index γstr is 1 in the usual perturbation theory, but equals 1/2 in the mean-field...

A study of time reversal symmetry of abelian anyons

Abstract We perform a study of time reversal symmetry of abelian anyons \( \mathcal{A} \) in 2+1 dimensions, in the spin structure independent cases. We will find the importance of the group \( \mathcal{C} \) of time-reversal-symmetric anyons modulo anyons composed from an anyon and its time reversal. Possible choices of local Kramers degeneracy are given by quadratic refinements...

DUNE sensitivities to the mixing between sterile and tau neutrinos

Abstract Light sterile neutrinos can be probed in a number of ways, including electroweak decays, cosmology and neutrino oscillation experiments. At long-baseline experiments, the neutral-current data is directly sensitive to the presence of light sterile neutrinos: once the active neutrinos have oscillated into a sterile state, a depletion in the neutral-current data sample is...

Search for a heavy resonance decaying into a Z boson and a vector boson in the \( \nu \overline{\nu}\mathrm{q}\overline{\mathrm{q}} \) final state

Abstract A search is presented for a heavy resonance decaying into either a pair of Z bosons or a Z boson and a W boson (ZZ or WZ), with a Z boson decaying into a pair of neutrinos and the other boson decaying hadronically into two collimated quarks that are reconstructed as a highly energetic large-cone jet. The search is performed using the data collected with the CMS detector...

Fermionic one-particle states in curved spacetimes

Abstract We show that a notion of one-particle state and the corresponding vacuum state exists in general curved backgrounds for spin \( \frac{1}{2} \) fields. A curved spacetime can be equipped with a coordinate system in which the metric component g−− = 0. We separate the component of the left-handed massless Dirac field which is annihilated by the null vector ∂− and compute...

New worldsheet formulae for conformal supergravity amplitudes

Abstract We use 4d ambitwistor string theory to derive new worldsheet formulae for tree-level conformal supergravity amplitudes supported on refined scattering equations. Unlike the worldsheet formulae for super-Yang-Mills or supergravity, the scattering equations for conformal supergravity are not in general refined by MHV degree. Nevertheless, we obtain a concise worldsheet...

Conjecture on the butterfly velocity across a quantum phase transition

Abstract We study an anisotropic holographic bottom-up model displaying a quantum phase transition (QPT) between a topologically trivial insulator and a non-trivial Weyl semimetal phase. We analyze the properties of quantum chaos in the quantum critical region. We do not find any universal property of the Butterfly velocity across the QPT. In particular it turns out to be either...

Holographic subregion complexity under a thermal quench

Abstract We study the evolution of holographic subregion complexity under a thermal quench in this paper. From the subregion CV proposal in the AdS/CFT correspondence, the subregion complexity in the CFT is holographically captured by the volume of the codimension-one surface enclosed by the codimension-two extremal entanglement surface and the boundary subregion. Under a thermal...

The topologically twisted index of \( \mathcal{N} \) = 4 super-Yang-Mills on T 2 × S2 and the elliptic genus

Abstract We examine the topologically twisted index of \( \mathcal{N} \) = 4 super-Yang-Mills with gauge group SU(N ) on T 2×S2, and demonstrate that it receives contributions from multiple sectors corresponding to the freely acting orbifolds T2/ℤm × ℤn where N = mn. After summing over these sectors, the index can be expressed as the elliptic genus of a twodimensional \( \mathcal...

Lifshitz entanglement entropy from holographic cMERA

Abstract We study entanglement entropy in free Lifshitz scalar field theories holographically by employing the metrics proposed by Nozaki, Ryu and Takayanagi in [1] obtained from a continuous multi-scale entanglement renormalisation ansatz (cMERA). In these geometries we compute the minimal surface areas governing the entanglement entropy as functions of the dynamical exponent z...

Comments on the twisted punctures of Aeven class S theory

Abstract We point out that the USp symmetry associated to a full twisted puncture of a class S theory of type Aeven has the global anomaly associated to π4(USp) = ℤ2. We discuss manifestations of this fact in the context of the superconformal field theory R2,2N introduced by Chacaltana, Distler and Trimm. For example, we find that this theory can be thought of as a natural...

Final results of the search for νμ → νe oscillations with the OPERA detector in the CNGS beam

Abstract The OPERA experiment has discovered the tau neutrino appearance in the CNGS muon neutrino beam, in agreement with the 3 neutrino flavour oscillation hypothesis. The OPERA neutrino interaction target, made of Emulsion Cloud Chambers, was particularly efficient in the reconstruction of electromagnetic showers. Moreover, thanks to the very high granularity of the emulsion...

Gravitational memory in higher dimensions

Abstract It is shown that there is a universal gravitational memory effect measurable by inertial detectors in even spacetime dimensions d ≥ 4. The effect falls off at large radius r as r3−d. Moreover this memory effect sits at one corner of an infrared triangle with the other two corners occupied by Weinberg’s soft graviton theorem and infinite-dimensional asymptotic symmetries.

The all-loop conjecture for integrands of reggeon amplitudes in \( \mathcal{N}=4 \) SYM

Abstract In this paper we present the all-loop conjecture for integrands of Wilson line form factors, also known as reggeon amplitudes, in \( \mathcal{N}=4 \) SYM. In particular we present a new gluing operation in momentum twistor space used to obtain reggeon tree-level amplitudes and loop integrands starting from corresponding expressions for on-shell amplitudes. The introduced...

Naturalness and dark matter in a realistic intersecting D6-brane model

Abstract We revisit a three-family Pati-Salam model with a realistic phenomenology from intersecting D6-branes in Type IIA string theory compactified on a T6/(ℤ2 × ℤ2) orientifold, and study its naturalness in view of the current LHC and dark matter searches. We discuss spectrum and phenomenological features of this scenario demanding fine tuning better than 1%. This requirement...

Bulk phase shift, CFT Regge limit and Einstein gravity

Abstract The bulk phase shift, related to a CFT four-point function, describes two-to-two scattering at fixed impact parameter in the dual AdS spacetime. We describe its properties for a generic CFT and then focus on large N CFTs with classical bulk duals. We compute the bulk phase shift for vector operators using Regge theory. We use causality and unitarity to put bounds on the...

Axial anomaly in multi-Weyl and triple-point semimetals

Abstract We derive the expression of the abelian axial anomaly in the so-called multi-Weyl and triple-point crossing semimetals. No simplifying restrictions are assumed on the symmetry of the spectrum. Three different computation methods are considered: the perturbative quantum field theory procedure which is based on the evaluation of the one-loop Feynman diagrams, the Nielsen...
