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…
Finite-temperature correlations in a quantum spin chain near saturation
Dominic Blosser, Noam Kestin, Kirill Yu. Povarov +4
Inelastic neutron-scattering and finite-temperature density matrix renormalization group (DMRG) calculations are used to investigate the spin excitation spectrum of the Hei…
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 quenches in one-dimensional gapless systems: Does bosonization work?
Emanuele Coira, Federico Becca, Alberto Parola
We present a comparison between the bosonization results for quantum quenches and exact diagonalizations in microscopic models of interacting spinless fermions in a one-dimensional…
