Renormalization group analysis of directed percolation process: Towards multiloop calculation of scaling functions
Michal Hnatič, Matej Kecer, Tomáš Lučivjanský +1
In this work, we employ a field-theoretic renormalization group approach to study a paradigmatic model of directed percolation. We focus on the perturbative calculation of the equa…
Random cubic graph embedded in a hypercube: Entanglement spectrum and many-body localization
Frantisek Slanina
The schematic model of interacting spins is introduced, which combines the symmetry of hypercube with the simplicity of random regular graph with degree three, i.e. the random cubi…
Jamming of active particles in narrow pores: Implications for ratchet effect and diffusion coefficient
Šimon Pajger, František Slanina
We study the behavior of colloidal active particles interacting via steric repulsion in various quasi-1D geometries. We mainly focus on active particles with high Péclet number. We…
1D fluids with repulsive nearest-neighbour interactions: Low-temperature anomalies
Igor Travěnec, Ladislav Šamaj
A limited number of 2D and 3D materials under a constant pressure contract in volume upon heating isobarically; this anomalous phenomenon is known as the negative thermal expansion…
Contact value theorem for electric double layers with modulated surface charge density
Ladislav Šamaj
The contact value theorem was originally derived for Coulomb fluids of mobile charged particles in thermal equilibrium, in the presence of interfaces carrying a {\em uniform} surfa…
Anomalous Kinetics of a Multi-Species Reaction-Diffusion System: Effect of Random Velocity Fluctuations
Michal Hnatič, Matej Kecer, Tomáš Lučivjanský
Reaction-diffusion systems, which consist of the reacting particles subject to diffusion process, constitute one of the common examples of non-linear statistical systems. In low sp…

We study random velocity effects on a two-species reaction-diffusion system consisting of three reaction processes . Using the…
Electric double layers with modulated surface charge density: Exact 2D results
Ladislav Šamaj
Electric double layers (EDL) with counterions only, say electrons with the elementary charge , in thermal equilibrium at the inverse temperature are considered. In particul…
Anisotropic deformation of the 6-state clock model: Tricritical-point classification
Maria Polackova, Andrej Gendiar
The two-dimensional -state clock models exhibit the Berezinskii-Kosterlitz-Thouless (BKT) transition for since they are a subset of the isotropic XY model. We examine t…
Towards lattice-gas description of low-temperature properties above the Haldane and cluster-based Haldane ground states of a mixed spin-(1,1/2) Heisenberg octahedral chain
Katarina Karlova, Jozef Strecka, Johannes Richter
The rich ground-state phase diagram of the mixed spin-(1,1/2) Heisenberg octahedral chain was previously elaborated from effective mixed-spin Heisenberg chains, which were derived…

Milan Žukovič, Georgii Kalagov
We study effects of competing pairwise higher-order interactions (HOI) with alternating signs and exponentially decreasing intensity on critical behavior of the XY model. It is fou…
