Conformal field theory for inhomogeneous one-dimensional quantum systems: the example of non-interacting Fermi gases
(Stichting SciPost, 2017-02-13)
Inhomogeneous Fermi and quantum spin systems on lattices
(AMER INST PHYSICSMELVILLE, 2012)
We study the thermodynamic properties of a certain type of space-inhomogeneous Fermi and quantum spin systems on lattices. We are particularly interested in the case where the space scale of the inhomogeneities stays ...
Entanglement in spatially inhomogeneous many-fermion systems
(AMER PHYSICAL SOC, 2008)
We investigate entanglement of strongly interacting fermions in spatially inhomogeneous environments. To quantify entanglement in the presence of spatial inhomogeneity, we propose a local-density approximation (LDA) to the ...
Casimir energy due to inhomogeneous thin plates
(American Physical Society, 2020-02-18)
We study the Casimir energy due to a quantum real scalar field coupled to two planar, infinite, zerowidth, parallel mirrors with nonhomogeneous properties. These properties are represented, in the model we use, by scalar ...
Electronic transitions in quantum dots and rings induced by inhomogeneous off-centered light beams
(IOP Publishing, 2010-11)
We theoretically investigate the effect of inhomogeneous light beams with (twisted light) and without (plane-wave light) orbital angular momentum on semiconductor-based nanostructures, when the symmetry axes of the beam ...
Entanglement and control operations in Heisenberg 3-D interactions of two qubits
(Revista Mexicana de Física, 2010)
Orbital and spin dynamics of intraband electrons in quantum rings driven by twisted light
(Optical Society of America, 2011-11)
We theoretically investigate the effect that twisted light has on the orbital and spin dynamics of electrons in quantum rings possessing sizable Rashba spin-orbit interaction. The system Hamiltonian for such a strongly ...
Quantum irreversible decoherence behaviour in open quantum systems with few degrees of freedom: Application to 1H NMR reversion experiments in nematic liquid crystals
(American Institute of Physics, 2013-10)
An experimental study of NMR spin decoherence in nematic liquid crystals is presented. Decoherence dynamics can be put in evidence by means of refocusing experiments of the dipolar interactions. The experimental technique ...
Rabi oscillations in two-level semiconductor systems
(Pergamon-elsevier Science LtdOxfordInglaterra, 2005)
Long-time tails and anomalous slowing down in the relaxation of spatially inhomogeneous excitations in quantum spin chains
(American Physical SocCollege PkEUA, 2002)
