Spin Conductance in one-dimensional Spin-Phonon systems
Kim Louis, Xenophon Zotos
We present results for the spin conductance of the one dimensional spin-1/2 Heisenberg and XY model coupled to phonons. We apply an approach based on the Stochastic Series Expansio…
Quantum Monte Carlo simulation for the spin-drag conductance of the Hubbard model
K. Louis, C. Gros
In the situation of two electro-statically coupled conductors a current in one conductor may induce a current in the other one. We will study this phenomenon, called Coulomb drag,…
Stochastic Cluster Series expansion for quantum spin systems
Kim Louis, C. Gros
In this paper we develop a cluster-variant of the Stochastic Series expansion method (SCSE). For certain systems with longer-range interactions the SCSE is considerably more effici…
Quantum Monte Carlo simulation for the conductance of one-dimensional quantum spin systems
Kim Louis, Claudius Gros
Recently, the stochastic series expansion (SSE) has been proposed as a powerful MC-method, which allows simulations at low for quantum-spin systems. We show that the SSE allows…
Diverging magnetothermal response in the one-dimensional Heisenberg chain
Kim Louis, C. Gros
A current of magnetic moments will flow in the spin-1/2 Heisenberg chain in the presence of an external magnetic field and a temperature gradient along the chain. We show…
Fermi surface renormalization in Hubbard ladders
Kim Louis, J. V. Alvarez, Claudius Gros
We derive the one-loop renormalization equations for the shift in the Fermi-wavevectors for one-dimensional interacting models with four Fermi-points (two left and two right movers…
