Finite temperature dynamical correlations for the dimerized spin-1/2 chain
Emanuele Coira, Peter Barmettler, Thierry Giamarchi +1
We use the density matrix renormalization group method (DMRG) to compute the frequency and momentum resolved spin-spin correlation functions of a dimerized spin-1/2 chain under a m…
Temperature dependence of the NMR spin-lattice relaxation rate for spin-1/2 chains
E. Coira, P. Barmettler, T. Giamarchi +1
We use recent developments in the framework of time dependent matrix product state method (t-MPS) to compute the NMR relaxation rate for spin-1/2 chains under magnetic fiel…
Quantum gases in optical lattices
Peter Barmettler, Corinna Kollath
The experimental realization of correlated quantum phases with ultracold gases in optical lattices and their theoretical understanding has witnessed remarkable progress during the…
Impact of local integrals of motion to metastable non-equilibrium states
Peter Barmettler, Corinna Kollath
We analyse the stationary behaviour of correlations in a strongly correlated Bose gas out of equilibrium. The dynamics are triggered by a quench of the interaction starting from th…
Competition of spin and charge excitations in the Hubbard model
Bruno Sciolla, Akiyuki Tokuno, Shun Uchino +3
Motivated by recent experiments with ultracold fermionic atoms in optical lattices, we study finite temperature magnetic correlations, as singlet and triplet correlations, and the…
Nonequilibrium dynamical cluster theory
Naoto Tsuji, Peter Barmettler, Hideo Aoki +1
We study the effect of spatially nonlocal correlations on the nonequilibrium dynamics of interacting fermions by constructing the nonequilibrium dynamical cluster theory, a cluster…
