Spin polarization via decoherence in spin-orbit active media coupled to an electron reservoir
Luis A. González-Árraga, Bertrand Berche, Ernesto Medina
We study the spin polarization of mixed and entangled electron states in a four probe/beam splitter geometry with local Rashba and Dresselhaus interactions. A pair of maximally ent…
Classical Yang-Mills theory in condensed matter physics
Bertrand Berche, Ernesto Medina
Recently, gauge field theory approaches were extensively used in order to discuss the physical consequences of spin-orbit interactions in condensed matter physics. An SU(2)…
A thermodynamic counterpart of the Axelrod model of social influence: The one-dimensional case
Y. Gandica, E. Medina, I. Bonalde
We propose a thermodynamic version of the Axelrod model of social influence. In one-dimensional (1D) lattices, the thermodynamic model becomes a coupled Potts model with a bonding…
Spin superfluidity and spin-orbit gauge symmetry fixing
Bertrand Berche, Ernesto Medina, Alexander López
The Hamiltonian describing 2D electron gas, in a spin-orbit active medium, can be cast into a consistent non-Abelian gauge field theory leading to a proper definition of the spin c…
Chiral molecular films as electron polarizers and polarization modulators
Ernesto Medina, Floralba López, Mark Ratner +1
Recent experiments on electron scattering through molecular films have shown that chiral molecules can be efficient sources of polarized electrons even in the absence of heavy nucl…
