The generalized t-V model in one dimension
Marcin Szyniszewski, Evgeni Burovski
We develop a systematic strong coupling approach for studying an extended t-V model with interactions of a finite range. Our technique is not based on the Bethe ansatz and is appli…
Bound state formation and nature of the excitonic insulator phase in the extended Falicov-Kimball model
D. Ihle, M. Pfafferott, E. Burovski +2
Motivated by the possibility of pressure-induced exciton condensation in intermediate-valence Tm[Se,Te] compounds we study the Falicov-Kimball model extended by a finite f-hole val…
Critical Temperature Curve in the BEC-BCS Crossover
Evgeni Burovski, Evgeny Kozik, Nikolay Prokof'ev +2
The strongly-correlated regime of the BCS-BEC crossover can be realized by diluting a system of two-component fermions with a short-range attractive interaction. We investigate thi…
Exact treatment of exciton-polaron formation by Diagrammatic Monte Carlo
Evgeni Burovski, Holger Fehske, Andrei S. Mishchenko
We develop an approximation-free Diagrammatic Monte Carlo technique to study fermionic particles interacting with each other simultaneously through both an attractive Coulomb poten…
Diagrammatic Quantum Monte Carlo for Two-Body Problem: Exciton
E. A. Burovski, A. S. Mishchenko, N. V. Prokof'ev +1
We present a novel method for precise numerical solution of the irreducible two-body problem and apply it to excitons in solids. The approach is based on the Monte Carlo simulation…
