Near-adiabatic parameter changes in correlated systems: Influence of the ramp protocol on the excitation energy
Martin Eckstein, Marcus Kollar
We study the excitation energy for slow changes of the hopping parameter in the Falicov-Kimball model with nonequilibrium dynamical mean-field theory. The excitation energy vanishe…

Phase separation in the particle-hole asymmetric Hubbard model
M. Eckstein, M. Kollar, M. Potthoff +1
The paramagnetic phase diagram of the Hubbard model with nearest-neighbor (NN) and next-nearest-neighbor (NNN) hopping on the Bethe lattice is computed at half-filling and in the w…
