Krylov complexity and chaos in quantum mechanics

by considering the Krylov state complexity for states other than the TFD in chaotic quantum mechanics. Unlike the case of Krylov operator complexity, there are two types of Lanczos coefficients, an ... mechanics. – 7 – (2.15) (2.16) (2.17) (2.18) Here xˆ is the position operator, and α is a real positive constant. The reason why we take this Gaussian operator is that it is normalizable and thus well-defined

Entanglement entropy in conformal quantum mechanics

We consider sets of states in conformal quantum mechanics associated to generators of time evolution whose orbits cover different regions of the time domain. States labelled by a continuous global ... bipartite eigenstates of generators of non-global time evolution. In terms of the correspondence between radial conformal symmetries in Minkowski space-time and time evolution in conformal quantum mechanics

Bohmian mechanics of the three-slit experiment in the linear potential

interpretation [ 7 ] of quantum mechanics. In particular, we measure the Bohm trajectories as well as the quantum potential for this system. Quantum mechanics rests on a remarkable theoretical framework that ... an alternative interpretation of quantum mechanics [7]. In Bohm’s formulation, the motion of a particle is governed by classical equations of motion [ 11 ] made possible by the inclusion of a

As ... quantum mechanics like the SYK model [30–32], analytic results were only achieved for the initial growth [10, 33, 34], leaving the saturation in the late time unexplained. In this paper, we develop a

On the continuum mechanics of growing plant-like structures

generator is presented and utilized in this work. Since no growth formulations within the framework of continuum mechanics exist so far for plant like systems, a novel set of constitutive equations is shown ... . Furthermore, results of numerical simulations are shown, which represent the growth process of plant like biological structures.
