Long-time fermionic quantum transport with controlled full-state error using an adaptive reservoir-mode window
Mikhail Umanskii, Nataliya Arefyeva, Georgy Sultanov +2
Real-time simulations of interacting nanostructures coupled to fermionic reservoirs can require a growing number of environmental degrees of freedom to retain long-lived correlatio…
Pseudogap formation in the moderate correlated layered attractive Hubbard model
A. V. Belov, A. N. Rubtsov, B. Krippa
We consider the layered attractive Hubbard model with a moderate interaction strength at quarter filling. The Green's function, self-energy, and density of states are calculated fo…
Fluctuating local field method for the disordered Ising model
Daria Kuznetsova, Grigory V. Astretsov, Alexey N. Rubtsov
We present a method for computing thermal properties of classical spin clusters with arbitrarily chosen interactions between spins. For such systems, instability channels are \text…
Classical modelling of a bosonic sampler with photon collisions
M. Umanskii, A. N. Rubtsov
When the problem of boson sampling was first proposed, it was assumed that little or no photon collisions occur. However, modern experimental realizations rely on setups where coll…
Fluctuating local field approach to free energy of 1D molecules with strong collective electronic correlations
Yana S. Lyakhova, Evgeny A. Stepanov, Alexey N. Rubtsov
The impact of leading collective electronic fluctuations on a free energy of a prototype 1D model for molecular systems is considered within the recently developed Fluctuating Loca…
Proton fraction in neutron star matter: Dynamical mean-field approach
Maxim Velikanov, Alexey N. Rubtsov, Boris Krippa
Dynamical mean field theory (DMFT) is used to study neutron matter, both with and without admixture of the proton fraction. The system is approximated by the lattice Habbard model.…
