Quantum confinement effects on the optical phonons of CdTe quantum dots
(Academic Press LtdLondonInglaterra, 1998)
Discord and information deficit in the xx chain
(American Physical Society, 2013-07)
We examine the quantum correlations of spin pairs in the cyclic XX spin-1/2 chain in a transverse field through the analysis of the quantum discord, the geometric discord, and the information deficit. It is shown that while ...
Decoherence induced by a phase-damping reservoir
(Amer Physical SocCollege PkEUA, 2006)
Quantum gravity and the holographic dark energy cosmology
(2016-04-01)
The holographic dark energy model is obtained from a cosmological constant generated by generic quantum gravity effects giving a minimum length. By contrast, the usual bound for the energy density to be limited by the ...
SHAPIRO EFFECT IN INDUCTIVE QUANTUM CIRCUITS WITH CHARGE DISCRETENESS
(Universidad de Tarapacá., 2006)
A FLUORESCENCE QUENCHING METHOD FOR DETERMINATION OF COPPER IONS WITH CDTE QUANTUM DOTS
(Sociedad Chilena de Química, 2009)
Quantum chameleons
(2019-05-15)
We initiate a quantum treatment of chameleonlike particles, deriving classical and quantum forces directly from the path integral. It is found that the quantum force can potentially dominate the classical one by many orders ...
Quantum coherence and speed limit in the mean-field Dicke model of superradiance
(2020-11-16)
Dicke superrandiance is a cooperative phenomenon which arises from the collective coupling of an ensemble of atoms to the electromagnetic radiation. Here we discuss the quantifying of quantum coherence for the Dicke model ...
The Ground State Energy per Site of the Quantum and Classical Edwards-Anderson Spin Glass in the Thermodynamic Limit
(SPRINGERNEW YORK, 2012)
We derive general rigorous lower bounds for the average ground state energy per site e ((d)) of the quantum and classical Edwards-Anderson spin-glass model in dimensions d=2 and d=3 in the thermodynamic limit. For the ...
Entanglement and the speed of evolution of two interacting qubits
(IOP Publishing, 2013-02)
The time needed by a quantum system to reach a state fully distinguishable from the original one provides a natural way of determining how fast the corresponding dynamical evolution is. This orthogonality time admits a ...
