Dynamical stability of the weakly nonharmonic propeller-shaped planar Brownian rotator.

The Caldeira-Leggett master equation is utilized to investigate dynamical stability of molecular cogwheels modeled as a rigid, propeller-shaped planar rotator to match certain expected realistic physical situations.

Complexity is simple!

A bstractIn this note we investigate the role of Lloyd’s computational bound in holographic complexity. Our goal is to translate the assumptions behind Lloyd’s proof into the bulk language. In

Dynamical emergence of Markovianity in local time scheme

This paper introduces and analyse in depth a rather non-standard dynamical map that is imposed by the so-called local time scheme and provides quantitative criteria for dynamical emergence of time-coarse-grained Markovianity, for exact dynamics of an open system, as well as for operationally defined approximation of a closed or open many-particle system.

A local-time-induced unique pointer basis

There is a solution to the problem of asymptotic completeness in many-body scattering theory that offers a specific view of the quantum unitary dynamics which allows for the straightforward

The environment-induced-superselection model of the large-molecules conformational stability and transitions

The large molecules lie in the “border territory" between the “quantum" and the “classical". To which extent one should employ the classical or quantum-mechanical methods in describing their behavior

What Is “System”: The Information-Theoretic Arguments

Here, the possibility to manipulate a pair of mutually non-interacting, non-entangled systems to employ entanglement of the newly defined “(sub)systems” consisting the one and the same composite system is pointed out.

Entanglement Theory and a q Analogue Entangled State

Entangled state and entanglement theory in the quantum information are pre- sented. A q analogue entangled state is flrst put forward in this paper. It exhibits a much richer structure than ordinary

Decoherence due to internal mesoscopic environment: a possible experimental test

Abstract.Following the fundamentals of the Stern-Gerlach experiment, we propose for an experimental situation eventually revealing the decoherence effect due to the internal mesoscopic environment.

Preferred States, Predictability, Classicality and the Environment-Induced Decoherence

Selection of the preferred classical set of states in the process of decoherence is discussed with an emphasis on the role of correlations, information loss and entropy. Persistence of correlations

Environment-induced superselection rules

We show how the correlations of a quantum system with other quantum systems may cause one of its observables to behave in a classical manner. In particular, "reduction of the wave packet," postulated

On diagonalization of a composite-system observable. Separability

We develop a general algebraic method for investigating the diagonalizability of a composite-system observable in the, so-called, noncorrelated basis of the Hilbert state space of a composite

Consciousness and quantum interference—An experimental approach

After a discussion of the possible connections between quantum mechanics and consciousness, and an examination of the circumstances under which some properties of a macroscopic system may be
