Thermalization dynamics close to a quantum phase transition
Dario Patanè, Alessandro Silva, Fernando Sols +1
We investigate the dissipative dynamics of a quantum critical system in contact with a thermal bath. In analogy with the standard protocol employed to analyze aging, we study the r…
Quantum frustration of dissipation by a spin bath
D. D. Bhaktavatsala Rao, Heiner Kohler, Fernando Sols
We investigate the evolution of a central spin coupled to a spin bath without internal dynamics. We compare the cases where the bath couples to one or two components of the spin. I…
Dirac-point engineering and topological phase transitions in honeycomb optical lattices
B. Wunsch, F. Guinea, F. Sols
We study the electronic structure and the phase diagram of non-interacting fermions confined to hexagonal optical lattices. In the first part, we compare the properties of Dirac po…
Controlled generation of coherent matter-currents using a periodic driving field
C. E. Creffield, F. Sols
We study the effect of a strong, oscillating driving field on the dynamics of ultracold bosons held in an optical lattice. Modeling the system as a Bose-Hubbard model, we show how…
Andreev reflection in bosonic condensates
I. Zapata, F. Sols
We study the bosonic analog of Andreev reflection at a normal-superfluid interface where the superfluid is a boson condensate. We model the normal region as a zone where nonlinear…
Interactions and magnetism in graphene boundary states
B. Wunsch, T. Stauber, F. Sols +1
We analyze interaction effects on boundary states of single layer graphene. Near a half filled band, both short and long-ranged interactions lead to a fully spin polarized configur…
