A bstract The generators of radial conformal symmetries in Minkowski space-time can be mapped to the time evolution quantum mechanics. Within this correspondence we show that mechanics state associated inertial vacuum has structure a thermofield double. Such is built from bipartite “vacuum state”, ground hyperbolic evolution, which cover only part domain. When restricted finite domain one obtai...

Abstract The preparation of thermal equilibrium states is important for the simulation condensed matter and cosmology systems using a quantum computer. We present method to prepare such mixed with unitary operators demonstrate this technique experimentally gate-based processor. Our targets generation thermofield double hybrid quantum-classical variational approach motivated by quantum-approxima...

A bstract We discuss some implications of recent progress in understanding the black hole information paradox for complementarity de Sitter space. Extending work by two authors, we describe a bulk procedure that allows expelled through cosmological horizon to be received an antipodal observer. Generically, this transfer takes scrambling time t = H ? 1 log( S dS ). emphasize relies crucially on ...

different discrete models of population dynamics of certain insects have been investigated under various feasible conditions within the framework of nonlinear dynamics. evolutionary phenomena are discussed through bifurcation analysis leading to chaos. some tools of nonlinear dynamics, such as lyapunov characteristic exponents (lce), lyapunov numbers, correlation dimension, etc. are calculated ...

Out-of-time-order correlators (OTOCs) are a standard measure of quantum chaos. Of the four operators involved, one pair may be regarded as source and other probe. A usual approach, applicable to large-$N$ systems such SYK model, is replace actual with some mean-field perturbation solve for probe correlation function on double Keldysh contour. We show how obtain OTOC by combining two solutions p...

development programs formulated in order to influence and create change and improvement in people's lives, that entails the promotion of resources, opportunities and capabilities different sections of the population, as well as an improvement in the standards and quality of life. they are based on policies that presented in form concrete objectives and articles program. this policies and o...

in this paper, the optimal adaptive leader-follower consensus of linear continuous time multi-agent systems is considered. the error dynamics of each player depends on its neighbors’ information. detailed analysis of online optimal leader-follower consensus under known and unknown dynamics is presented. the introduced reinforcement learning-based algorithms learn online the approximate solution...
