Effects of chaotic dynamics on quantum friction
(American Physical Society, 2019-04-22)
By means of studying the evolution equation for the Wigner distributions of quantum dissipative systems we derive the quantum corrections to the classical Liouville dynamics, taking into account the standard quantum friction ...
Signatures of classical structures in the leading eigenstates of quantum dissipative systems
(American Physical Society, 2017-09)
By analyzing a paradigmatic example of the theory of dissipative systems - the classical and quantum dissipative standard map - we are able to explain the main features of the decay to the quantum equilibrium state. The ...
Classical to quantum correspondence in dissipative directed transport
(American Physical Society, 2015-11)
We compare the quantum and classical properties of the (quantum) isoperiodic stable structures [(Q)ISSs],which organize the parameter space of a paradigmatic dissipative ratchet model, i.e., the dissipative modifiedkicked ...
General theory of measurement with two copies of a quantum state
(American Physical Society, 2009-07)
We analyze the results of the most general measurement on two copies of a quantum state. We show that by using two copies of a quantum state it is possible to achieve an exponential improvement with respect to known methods ...
Quantum state transfer in a XX chain with impurities
(IOP Publishing, 2011-01)
One spin excitation states are involved in the transmission of quantum states and entanglement through a quantum spin chain, the localization properties of these states are crucial to achieve the transfer of information ...
Entropy, fidelity, and double orthogonality for resonance states in two-electron quantum dots
(American Physical Society, 2010-04)
Resonance states of a two-electron quantum dots are studied using a variational expansion with both real basis-set functions and complex scaling methods. The two-electron entanglement (linear entropy) is calculated as a ...
Correspondence behavior of classical and quantum dissipative directed transport via thermal noise
(American Physical Society, 2016-04)
We systematically study several classical-quantum correspondence properties of the dissipative modifiedkicked rotator, a paradigmatic ratchet model. We explore the behavior of the asymptotic currents for finite effvalues ...
Relevant out-of-Time-order correlator operators: footprints of the classical dynamics
(American Physical Society, 2020-11)
The out-of-time-order correlator (OTOC) has recently become relevant in different areas where it has been linked to scrambling of quantum information and entanglement. It has also been proposed as a good indicator of quantum ...
Three-dimensional classical and quantum stable structures of dissipative systems
(American Physical Society, 2019-01)
We study the properties of classical and quantum stable structures in a three-dimensional (3D) parameter space corresponding to the dissipative kicked top. This is a model system in quantum and classical chaos that gives ...
Quantum control landscape for a two-level system near the quantum speed limit
(IOP Publishing, 2018-08)
The core problem in optimal control theory applied to quantum systems is to determine the temporal shape of an applied field in order to maximize the expected value of some physical observable. The complexity of this ...
