Hybrid quantum-classical systems: statistics, entropy, microcanonical ensemble and its connection to the canonical ensemble
J. L. Alonso, C. Bouthelier-Madre, A. Castro +2
We describe in detail a mathematical framework in which statistical ensembles of hybrid classical-quantum systems can be properly described. We show how a maximum entropy principle…
About the computation of finite temperatureensemble averages of hybrid quantum-classicalsystems with Molecular Dynamics
J. L. Alonso, C. Bouthelier, A. Castro +2
Molecular or condensed matter systems are often well approximated by hybrid quantum-classical models: the electrons retain their quantum character, whereas the ions are considered…
Entropy and canonical ensemble of hybrid quantum classical systems
J. L. Alonso, C. Bouthelier, A. Castro +2
In this work we generalize and combine Gibbs and von Neumann approaches to build, for the first time, a rigorous definition of entropy for hybrid quantum-classical systems. The res…
Experimental evidence of spin-orbit torque from metallic interfaces
A. Anadón, R. Guerrero, J. A. Jover-Galtier +6
Spin currents can modify the magnetic state of ferromagnetic ultrathin films through spin-orbit torque. They may be generated by means of spin-orbit interaction by either bulk or i…
Ehrenfest statistical dynamics in chemistry: study of decoherence effects
J. L. Alonso, P. Bruscolini, A. Castro +3
In previous works, we introduced a geometric route to define our Ehrenfest Statistical Dynamics (ESD) and we proved that, for a simple toy-model, the resulting ESD does not preserv…
Tensorial dynamics on the space of quantum states
J. F. Cariñena, J. Clemente-Gallardo, J. A. Jover-Galtier +1
A geometric description of the space of states of a finite-dimensional quantum system and of the Markovian evolution associated with the Kossakowski-Lindblad operator is presented.…
Tangent bundle geometry from dynamics: application to the Kepler problem
J. F. Cariñena, J. Clemente-Gallardo, J. A. Jover-Galtier +1
In this paper we consider a manifold with a dynamical vector field and inquire about the possible tangent bundle structures which would turn the starting vector field into a second…
Lie systems and Schrödinger equations
J. F. Cariñena, J. Clemente-Gallardo, J. A. Jover-Galtier +1
We prove that -dependent Schrödinger equations on finite-dimensional Hilbert spaces determined by -dependent Hermitian Hamiltonian operators can be described through Lie syst…
Comment on "Correlated electron-nuclear dynamics: Exact factorization of the molecular wavefunction" [J. Chem. Phys. 137, 22A530 (2012)]
J. L. Alonso, J. Clemente-Gallardo, P. Echenique-Robba +1
In spite of the relevance of the proposal introduced in the recent work A. Abedi, N. T. Maitra and E. K. U. Gross, J. Chem. Phys. 137, 22A530, 2012, there is an important ingredien…
