Localization pattern of a mobile impurity in the disordered Kitaev chain
A. V. Sadovnikov, A. N. Rubtsov
We study a mobile impurity coupled to a Kitaev chain with chemical-potential disorder and ask whether the impurity behavior distinguishes different regimes of the host system. Exac…
Quantized Collective Fluctuations in Correlated Fermion Systems
S. S. Onuchin, Ya. S. Lyakhova, L. D. Silakov +1
Collective excitations in fermionic systems play a crucial role in determining their physical properties. An important challenge is to develop efficient theoretical approaches for…
Sample space filling analysis for boson sampling validation
A. A. Mazanik, A. N. Rubtsov
Achieving a quantum computational advantage regime, and thus providing evidence against the extended Church-Turing thesis, remains one of the key challenges of modern science. Boso…
Mean Field Decoupling of Single Impurity Anderson Model through Auxiliary Majorana Fermions
Irakli Titvinidze, Julian Stobbe, Alexey N. Rubtsov +1
We present a method to study the time evolution of the single impurity Anderson model which exploits a mean field decoupling of the interacting impurity and the non-interacting bat…
Towards out of equilibrium impurity solver for the Dynamical Mean Field Theory
A. Karpov, G. Sultanov, E. Polyakov +1
The Dynamical Mean Field Theory (DMFT) is a powerful tool for calculating highly correlated systems (both bosonic and fermionic) in a state of thermodynamic equilibrium. However, i…
Diagrammatic routes to nonlocal correlations beyond dynamical mean field theory
G. Rohringer, H. Hafermann, A. Toschi +6
Strong electronic correlations pose one of the biggest challenges to solid state theory. We review recently developed methods that address this problem by starting with the local,…
