Universal diffusive decay of correlations in gapped one-dimensional systems
Akos Rapp, Gergely Zarand
We apply a semiclassical approach to express finite temperature dynamical correlation functions of gapped spin models analytically. We show that the approach of [A. Rapp, G. Zarand…
Trionic phase of ultracold fermions in an optical lattice: A variational study
Akos Rapp, Walter Hofstetter, Gergely Zarand
To investigate ultracold fermionic atoms of three internal states (colors) in an optical lattice, subject to strong attractive interaction, we study the attractive three-color Hubb…
Color Superfluidity and "Baryon" Formation in Ultracold Fermions
Akos Rapp, Gergely Zarand, Carsten Honerkamp +1
We study fermionic atoms of three different internal quantum states (colors) in an optical lattice, which are interacting through attractive on site interactions, U<0. Using a vari…
Dynamical correlations and quantum phase transition in the quantum Potts model
Akos Rapp, Gergely Zarand
We present a detailed study of the finite temperature dynamical properties of the quantum Potts model in one dimension.Quasiparticle excitations in this model have internal quantum…
