Local spin description of fermions on a lattice
Adam Wyrzykowski
A local transformation from fermionic operators to spin matrices is proposed and studied in this work. For this purpose, a system of fermions on a lattice is considered and one app…
Constraints of kinematic bosonization in two and higher dimensions
Arkadiusz Bochniak, Blazej Ruba, Jacek Wosiek +1
Contrary to the common wisdom, local bosonizations of fermionic systems exist in higher dimensions. Interestingly, resulting bosonic variables must satisfy local constraints of a g…
Analysis of the Breakdown of Exponential Decays of Resonances
Adam Wyrzykowski
In the paper, a simple model of alpha decay with Dirac delta potential is studied. The model leads to breakdown of the exponential decay and to power law behavior at asymptotic tim…
Satisfying positivity requirement in the Beyond Complex Langevin approach
Adam Wyrzykowski, Błażej Ruba
The problem of finding a positive distribution, which corresponds to a given complex density, is studied. By the requirement that the moments of the positive distribution and of th…
Explicit positive representation for weights on
Błażej Ruba, Adam Wyrzykowski
It is an old idea to replace averages of observables with respect to a complex weight by expectation values with respect to a genuine probability measure on complexified space. Thi…
