Concentrating Energy by Measurement
Almut Beige, Antonio Capolupo, Andreas Kurcz +2
In a recent article [A. Kurcz et al., Phys. Rev. A 81, 063821 (2010)] we predicted an energy concentrating mechanism in composite quantum systems. Its result is a non-zero stationa…
Reply to Comment on: Hawking radiation from ultrashort laser pulse filaments
F. Belgiorno, S. L. Cacciatori, M. Clerici +6
A comment by R. Schutzhold et al. raises possible concerns and questions regarding recent measurements of analogue Hawking radiation. We briefly reply to the opinions expressed in…
Universal Markovian reduction of Brownian particle dynamics
Rocco Martinazzo, Bassano Vacchini, Keith H. Hughes +1
Non-Markovian processes can often be turned Markovian by enlarging the set of variables. Here we show, by an explicit construction, how this can be done for the dynamics of a Brown…
Initial correlations in open system's dynamics: The Jaynes-Cummings model
A. Smirne, H. -P. Breuer, J. Piilo +1
Employing the trace distance as a measure for the distinguishability of quantum states, we study the influence of initial correlations on the dynamics of open systems. We concentra…
Programmable entanglement oscillations in a non Markovian channel
Simone Cialdi, Davide Brivio, Enrico Tesio +1
We suggest and demonstrate an all-optical experimental setup to observe and engineer entanglement oscillations of a pair of polarization qubits in a non-Markovian channel. We gener…
Phase-space characterization of complexity in quantum many-body dynamics
Vinitha Balachandran, Giuliano Benenti, Giulio Casati +1
We propose a phase-space Wigner harmonics entropy measure for many-body quantum dynamical complexity. This measure, which reduces to the well known measure of complexity in classic…
Soliton-like solutions to the ordinary Schroedinger equation
Michel Zamboni-Rached, Erasmo Recami
In recent times it has been paid attention to the fact that (linear) wave equations admit of "soliton-like" solutions, known as Localized Waves or Non-diffracting Waves, which prop…
Programmable purification of type-I polarization-entanglement
Simone Cialdi, Davide Brivio, Matteo G A Paris
We suggest and demonstrate a scheme to compensate spatial and spectral decoherence effects in the generation of polarization entangled states by type-I parametric downconversion. I…
Jump-diffusion unravelling of a non Markovian generalized Lindblad master equation
A. Barchielli, C. Pellegrini
The "correlated-projection technique" has been successfully applied to derive a large class of highly non Markovian dynamics, the so called non Markovian generalized Lindblad type…
Stochastic Schrödinger equations and memory
A. Barchielli, P. Di Tella, C. Pellegrini +1
By starting from the stochastic Schrödinger equation and quantum trajectory theory, we introduce memory effects by considering stochastic adapted coefficients. As an example of a n…
Nakajima-Zwanzig versus time-convolutionless master equation for the non-Markovian dynamics of a two-level system
Andrea Smirne, Bassano Vacchini
We consider the exact reduced dynamics of a two-level system coupled to a bosonic reservoir, further obtaining the exact time-convolutionless and Nakajima-Zwanzig non-Markovian equ…
Computing the distance between quantum channels: Usefulness of the Fano representation
Giuliano Benenti, Giuliano Strini
The diamond norm measures the distance between two quantum channels. From an operational vewpoint, this norm measures how well we can distinguish between two channels by applying t…
The role of chaos in quantum communication through a dynamical dephasing channel
Gabriela Barreto Lemos, Giuliano Benenti
In this article we treat the subject of chaotic environments with few degrees of freedom in quantum communication by investigating a conservative dynamical map as a model of a deph…
Dielectric black holes induced by a refractive index perturbation and the Hawking effect
F. Belgiorno, S. L. Cacciatori, G. Ortenzi +3
We consider a 4D model for photon production induced by a %superluminal refractive index perturbation in a dielectric medium. We show that, in this model, we can infer the presence…
Quantum master equation for collisional dynamics of massive particles with internal degrees of freedom
Andrea Smirne, Bassano Vacchini
We address the microscopic derivation of a quantum master equation in Lindblad form for the dynamics of a massive test particle with internal degrees of freedom interacting through…
Exact master equations for the non-Markovian decay of a qubit
Bassano Vacchini, Heinz-Peter Breuer
Exact master equations describing the decay of a two-state system into a structured reservoir are constructed. Employing the exact solution for the model we determine analytical ex…
