Dynamics of zero-point energy and two-slit phenomena for photons

A. Widom, J. Swain, Y. N. Srivastava +2

An earlier forward and backward in time formalism developed by us to discuss non-relativistic electron diffraction is generalized to the relativistic case and here applied to photo…

Polaron picture of the two-photon quantum Rabi model

Lei Cong, Xi-Mei Sun, Maoxin Liu +2

We employ a polaron picture to investigate the properties of the two-photon quantum Rabi model (QRM), which describes a two-level or spin-half system coupled with a single bosonic…

Effects of Lorentz boosts on Dirac bispinor entanglement

Victor A. S. V. Bittencourt, Alex E. Bernardini, Massimo Blasone

In this paper we describe the transformation properties of quantum entanglement encoded in a pair of spin 1/2 particles described via Dirac bispinors. Due to the intrinsic parity-s…

Nonunitary Newtonian Gravity Makes Semiclassical Gravity Viable for All Practical Purposes

Sergio De Filippo

Semiclassical Gravity replaces the energy momentum tensor with its expectation value in Einstein equations, this making the Einstein tensor $G_{μν}…

Quantum phase transition and spontaneous symmetry breaking in a nonlinear quantum Rabi model

Zu-Jian Ying, Lei Cong, Xi-Mei Sun

The experimental advance on light-matter interaction into strong couplings has invalidated Jaynes-Cummings model and brought quantum Rabi model (QRM) to more relevance. The QRM onl…

Exact non-Markovian dynamics of Gaussian quantum channels: Finite-time and asymptotic regimes

Gianpaolo Torre, Fabrizio Illuminati

We investigate the Markovian and non-Markovian dynamics of Gaussian quantum channels, exploiting a recently introduced necessary and sufficient criterion and the ensuing measure of…

Global Dirac bispinor entanglement under Lorentz boosts

Victor A. S. V. Bittencourt, Alex E. Bernardini, Massimo Blasone

The effects of Lorentz boosts on the quantum entanglement encoded by a pair of massive spin one-half particles are described according to the Lorentz covariant structure described…

On the canonical quantization of the electromagnetic field and the emergence of gauge invariance

M. Blasone, E. Celeghini, P. Jizba +2

In the framework of the canonical quantization of the electromagnetic field, we impose as primary condition on the dynamics the positive definiteness of the energy spectrum. This i…

A two-particle simulation of Nonunitary Newtonian Gravity

Giovanni Scelza, Filippo Maimone, Adele Naddeo

The result of a numerical simulation of two interacting particles in the framework of Nonunitary Newtonian Gravity is presented here. Particles are held close together by a 3-d har…
