Anomalous scaling of conductivity in integrable fermion systems
P. Prelovsek, S. El Shawish, X. Zotos +1
We analyze the high-temperature conductivity in one-dimensional integrable models of interacting fermions: the t-V model (anisotropic Heisenberg spin chain) and the Hubbard model,…
Finite Temperature Dynamical Correlations using the Microcanonical Ensemble and the Lanczos Algorithm
M. W. Long, P. Prelovsek, S. El Shawish +2
We show how to generalise the zero temperature Lanczos method for calculating dynamical correlation functions to finite temperatures. The key is the microcanonical ensemble, which…
Reactive Hall response
X. Zotos, F. Naef, M. Long +1
The zero temperature Hall constant R_H, described by reactive (nondissipative) conductivities, is analyzed within linear response theory. It is found that in a certain limit, R_H i…
Hole-hole correlations in the limit of the Hubbard model and the stability of the Nagaoka state
M. Long, X. Zotos
We use exact diagonalisation in order to study the infinite - limit of the two dimensional Hubbard model. As well as looking at single-particle correlations, such as $n_{{\bf k…
