A learning by confusion approach to characterize phase transitions
Monika Richter-Laskowska, Marcin Kurpas, Maciej Maśka
Recently, the learning by confusion (LBC) approach has been proposed as a machine learning tool to determine the critical temperature Tc of phase transitions without any prior know…
Unconventional topological transitions in a self-organized magnetic ladder
Maciej M. Maśka, Nicholas Sedlmayr, Aksel Kobiałka +1
It is commonly assumed that topological phase transitions in topological superconductors are accompanied by a closing of the topological gap or a change of the symmetry of the syst…
Dimerization-induced topological superconductivity in a Rashba nanowire
Aksel Kobiałka, Nicholas Sedlmayr, Maciej M. Maśka +1
We analyze influence of a dimerization on the topological phases of the Rashba nanowire proximitized to a superconducting substrate. We find that periodic alternations of the hoppi…
A machine learning approach to the Berezinskii-Kosterlitz-Thouless transition in classical and quantum models
M. Richter-Laskowska, H. Khan, N. Trivedi +1
The Berezinskii-Kosterlitz-Thouless transition is a very specific phase transition where all thermodynamic quantities are smooth. Therefore, it is difficult to determine the critic…
Temperature-driven BCS-BEC crossover in a coupled boson-fermion system
Maciej M. Maśka, Nandini Trivedi
We propose a simple bose-fermi model in two dimensions, with a coupling that converts pairs of opposite spin fermions into localized bosons and vice versa. We show that tracing out…
and molecules with an ab initio optimization of wave functions in correlated state: Electron-proton couplings and intermolecular microscopic parameters
Andrzej P. Kądzielawa, Agata Bielas, Marcello Acquarone +3
The hydrogen molecules and are analyzed with electronic correlations taken into account between the electrons exactly. The optimal single-particle Slater orbit…
Efficiency for preforming molecules from mixtures of light Fermi and heavy Bose atoms in optical lattices: the strong-coupling-expansion method
Anzi Hu, J. K. Freericks, M. M. Maśka +1
We discuss the application of a strong-coupling expansion (perturbation theory in the hopping) for studying light-Fermi-heavy-Bose (like K-Rb) mixtures in optical lat…
