A top-down view of the classical limit of quantum mechanics
(World Scientific, 2016)
At present there is a consensus about the fact that the emergence of the classical world from the underlying quantum reality involves the physical phenomenon of decoherence, which is usually studied in the version proposed ...
Decoherence and loss of entanglement in acoustic black holes
(American Physical Society, 2012-06)
We study the process of decoherence in acoustic black holes. We focus on the ion trap model proposed by Horstmann et al., but the formalism is general to any experimental implementation. For that particular setup, we compute ...
Weak-coupling study of decoherence of a qubit in disordered magnetic environments
(American Physical Society, 2009-12)
We study the decoherence of a qubit weakly coupled to frustrated spin baths. We focus on spin baths described by the classical Ising spin glass and the quantum random transverse Ising model which are known to have complex ...
Decoherence and intertheory relations in quantum realismDecoherencia y relaciones interteóricas en el realismo cuántico
(Universidad Nacional de QuilmesUniversidad Nacional de Tres de Febrero, 2019-04-01)
The complex relation between quantum mechanics and classical mechanics is crucial in the philosophy of modern physics, and it cuts across current quantum physics. This paper is divided in two parts. In the first part I ...
Remanent quantum correlations in dissipative qubits
(Elsevier Science, 2013-08-02)
Starting from the exact evolution of a Markovian dissipative quantum walk, a non-Markovian decoherence of two qubits interacting with a phonon thermal bath has been investigated analytically using quantum information tools. ...
Dynamics and decoherence in nonideal Thouless quantum motors
(American Physical Society, 2017-04-15)
Different proposals for adiabatic quantum motors (AQMs) driven by DC currents have recently attracted considerable interest. However, the systems studied are often based on simplified models with highly ideal conditions ...
Quantum correlations and coherence between two particles interacting with a thermal bath
(IOP Publishing, 2017-05)
Quantum correlations and coherence generated between two free spinless particles in the lattice, interacting with a common quantum phonon bath, are studied. The reduced density matrix is solved using the Markov approach. ...
The effect of random coupling coefficients on decoherence
(World Scientific, 2010-03)
The aim of this letter is to analyze the effect on decoherence of the randomness of the coupling coefficients involved in the interaction Hamiltonian. By studying the spin-bath model with computer simulations, we show that ...
Is the decoherence of a system the result of its interaction with the environment?
(World Scientific, 2010-11)
According to a usual reading, decoherence is a process resulting from the interaction between a small system and its large environment where information and energy are dissipated. The particular models treated in the ...
Decoherence in composite quantum open systems: The effectiveness of unstable degrees of freedom
(World Scientific, 2006-12)
The effect induced by an environment on a composite quantum system is studied. The model considers the composite system as comprised by a subsystem A coupled to a subsystem B which is also coupled to an external environment. ...
