Disorder Enhanced Thermalization in Interacting Many-Particle System
Chakradhar Rangi, Herbert F Fotso, Hanna Terletska +2
We introduce an extension of the non-equilibrium dynamical mean field theory to incorporate the effects of static random disorder in the dynamics of a many-particle system by integ…
Single- and two-particle finite size effects in interacting lattice systems
Sergei Iskakov, Hanna Terletska, Emanuel Gull
Simulations of extended quantum systems are typically performed by extrapolating results of a sequence of finite-system-size simulations to the thermodynamic limit. In the quantum…
One- and two-particle properties of the weakly interacting two-dimensional Hubbard model in proximity to the van Hove singularity
B. D. E. McNiven, Hanna Terletska, G. T. Andrews +1
We study the weak-coupling limit of the Hubbard model on a two-dimensional square lattice using a direct perturbative approach. Aided by symbolic computational tools…
Nonequilibrium DMFT+CPA for Correlated Disordered Systems
Eric Dohner, Hanna Terletska, Ka-Ming Tam +2
We present a solution for the nonequilibrium dynamics of an interacting disordered system. The approach adapts the combination of the equilibrium dynamical mean field theory (DMFT)…
Dynamical Cluster Approximation Study of Electron Localization in the Extended Hubbard Model
Hanna Terletska, Sergei Iskakov, Thomas Maier +1
We perform a detailed study of the phase transitions and mechanisms of electron localization in the extended Hubbard model using the dynamical cluster approximation on a $2\times 2…
Dynamical mean-field theory of the Anderson-Hubbard model with local and non-local disorder in tensor formulation
A. Weh, Y. Zhang, A. Östlin +7
To explore correlated electrons in the presence of local and non-local disorder, the Blackman-Esterling-Berk method for averaging over off-diagonal disorder is implemented into dyn…
