seminar by Dr. Marko Milivojević /NanoLab, QTP Center, Faculty of Physics, University of Belgrade, Serbia February 20, 2020 at 13:30 in SJ1S24, Jesenna 5, 040 01 Košice Three-spin interactions in three-qubit systems at thermal equilibrium can be used for simple and efficient creation of maximally entangled states. We do not require set of gates to achieve this goal; rather, maximal thermal entanglement naturally arises by…

seminar by prof. Lubos Mitas / North Carolina State University July 15, 2019 at 10:30 in SA1A1 (P1) lecture hall, Institute of Physics, Park Angelinum 9, Košice I will present a short introduction into the electronic structure quantum Monte Carlo (QMC) based on sampling of particles coordinates. These methods typically employ fixed-node approximations to deal with the fermion signs. I will show  examples of current…

In our works we apply quantum field methods developed initially to describe interactions between elementary particles to the problems of statistical physics, namely to the fully developed hydrodynamic turbulence. The general feature of such models of statistical physics like critical behaviour and turbulence is presence of strong fluctuations, and, therefore, the presence of divergences in perturbation theory and absence of small perturbation parameter. In this…
