Phase transition of the six-state clock model observed from the entanglement entropy
Roman Krčmár, Andrej Gendiar, Tomotoshi Nishino
The Berezinskii-Kosterlitz-Thouless (BKT) transitions of the six-state clock model on the square lattice are investigated by means of the corner-transfer matrix renormalization gro…
Quasi-universality in mixed counterions systems
M. Trulsson, L. Samaj, E. Trizac
The screening of plate-plate interactions by counterions is an age-old problem. We revisit this classic question when counterions exhibit a distribution of charges. While it is exp…
1-out-of-2 Oblivious transfer using flawed Bit-string quantum protocol

Critical properties of the eight-vertex model in a field
Roman Krčmár, Ladislav Šamaj
The general eight-vertex model on a square lattice is studied numerically by using the Corner Transfer Matrix Renormalization Group method. The method is tested on the symmetric (z…
The interference effects of multi-channel pion-pion scattering contributions to the final states of - and -meson family decays
Yu. S. Surovtsev, P. Bydžovský, T. Gutsche +3
It is shown that the basic shape of dipion mass distributions in the two-pion transitions of both charmonia and bottomonia states are explained by an unified mechanism based on the…
