Calculation of density of states of transition metals: from bulk sample to nanocluster
Petr V. Borisyuk, Oleg S. Vasiliev, Yaroslav V. Zhumagulov +4
The technique is presented of restoring the electronic density of states of the valence band from data of X-ray photoelectron spectroscopy. The originality of the technique consist…
Momentum distribution and non-Fermi liquid behaviour in low-doped two-orbital model: finite-size cluster quantum Monte Carlo approach
Vladimir A. Kashurnikov, Andrey V. Krasavin, Yaroslav V. Zhumagulov
The two-dimensional two-orbital Hubbard model is studied with the use of finite-size cluster worldline quantum Monte Carlo algorithm. This model is widely used for simulation of th…
Numerical study of vortex system quantum melting
M. V. Zyubin, I. A. Rudnev, V. A. Kashurnikov
We report a numerical study of the vortex system in the two dimensional II-type superconductors. We have proposed a phenomenological model that takes into account quantum fluctuati…
Universal SSE algorithm for Heisenberg model and Bose Hubbard model with interaction
M. V. Zyubin, V. A. Kashurnikov
We propose universal SSE method for simulation of Heisenberg model with arbitrary spin and Bose Hubbard model with interaction. We report on the first calculations of soft-core bos…
Critical Temperature Shift in Weakly Interacting Bose Gas
Nikolay Prokof'ev, Boris Svistunov, V. A. Kashurnikov
With a high-performance Monte Carlo algorithm we study the interaction-induced shift of the critical point in weakly interacting three-dimensional -theory (which includes qu…
Quantum spin chains in a magnetic field
V. A. Kashurnikov, N. V. Prokof'ev, B. V. Svistunov +1
We demonstrate that the ``worm'' algorithm allows very effective and precise quantum Monte Carlo (QMC) simulations of spin systems in a magnetic field, and its auto-correlation tim…
