A classical particle that is initially in a classically allowed region of a potential is not confined to this region for all time if its energy is complex. Rather, the particle may travel through com...
Time-delay of classical and quantum scattering processes: a conceptual overview and a general definition
Time-delay classical quantum scattering processes conceptual overview general definition
2010/11/8
We present a step by step introduction to the notion of time-delay in classical and quantum mechanics, with the aim of clarifying its foundation at a conceptual level. In doing so, we motivate the in...
Spin entanglement of two spin-1/2 particles in a classical gravitational field
Spin entanglement spin-1/2 particles classical gravitational field
2010/11/8
The effect of a classical gravitational field on the spin entanglement of a system of two spin-1/2 particles moving in the curved spacetime is discussed. The system is described by a two-particle Gaus...

Device-independent tests classical quantum dimensions
2010/11/8
We address the problem of testing the dimensionality of classical and quantum systems in a `black-box' scenario. We develop a general formalism for tackling this problem. This allows us to derive lowe...
Comparison of Thermodynamic Characteristics in Quantum and Classical Approaches and Game Theory
Comparison Thermodynamic Characteristics Quantum Classical Approaches Game Theory
2010/11/11
We fix the temperature $T$ and consider mean energy and entropy as two players of a game. As a result, basic formulas for the quantum mean energy and the quantum entropy are derived. We compare also t...
Rotational Symmetry of Classical Orbits, Arbitrary Quantization of Angular Momentum and the Role of Gauge Field in Two-Dimensional Space
Rotational Symmetry Classical Orbits Arbitrary Quantization Angular Momentum
2010/11/11
We study the quantum-classical correspondence in terms of coherent wave functions of a charged particle in two-dimensional central-scalar-potentials as well as the gauge field of a magnetic flux in t...
Classical and Quantum Mechanics with Poincare-Snyder Relativity
Classical Quantum Mechanics Poincare-Snyder Relativity
2010/11/11
The Poincar\'e-Snyder relativity was introduced in an earlier paper of ours as an extended form of Einstein relativity obtained by appropriate limiting setting of the full Quantum Relativity. The latt...
Non-classical correlation of cascaded photon pairs emitted from quantum dot
Non-classical correlation cascaded photon pairs emitted quantum dot
2010/11/5
We studied the quantum correlation between the photon pairs generated by biexciton cascade decays of self-assembled quantum dots, and determined the temperature behavior associated with so-called sudd...
Fluctuations in classical adiabatic processes: A general description and the emergence of a classical geometric angle
classical adiabatic processes general description classical geometric angle
2010/10/27
The intrinsic dynamical fluctuations neglected by the conventional classical adiabatic theorem
are described by a general differential equation. As a simple application, it is found that the
dynamic...

In this paper we study the quantum wave packet and the Feynman-de Broglie-Bohm propagator of the linearized Schuch-Chung-Hartmann equation along a classical trajetory.
Entanglement-Enhanced Classical Communication over a Noisy Classical Channel
Entanglement-Enhanced Classical Communication Noisy Classical Channel
2010/11/5
We present and experimentally demonstrate a communication protocol that employs shared entanglement to reduce errors when sending a bit over a particular noisy classical channel. Specifically, it is s...
The U(1) Lattice Gauge Theory Universally Connects All Classical Models with Continuous Variables, Including Background Gravity
Lattice gauge theory Statistical mechanics Quantum information
2010/11/4
We show that the partition function of many classical models with continuous degrees of freedom, e.g. abelian lattice gauge theories and statistical mechanical models, can be written as the partition...

This article (for the Oxford Handbook of Philosophy of Physics) focuses on two of the main problems raising interpretational issues in quantum mechanics, namely the notorious measurement problem and t...

Direct probing non-classical single-photon wavepacket
2010/10/29
We investigate quantum properties of pulsed light fields point-by-point in phase space. We probe the negative region of the Wigner function of a single photon state generated by means of waveguided pa...
In this paper we analyze perturbatively a g phi^4 classical field theory with and without temperature. In order to do that, we make use of a path-integral approach developed some time ago for classic...
