Field digitization scaling in a ZNU(1)\mathbb{Z}_N \subset U(1) symmetric model

This paper proposes a "field digitization scaling" framework that treats the number of discrete field values NN as a renormalization group coupling, successfully applying it to relate the 2D classical clock model to the XY model and its quantum gauge theory counterpart to enable continuum limit analysis in quantum simulations.

Irreversibility and symmetry breaking in the creation and annihilation of defects in active living matter

This study reveals that defect creation and annihilation in diverse active living systems exhibit spatial symmetry breaking and irreversibility driven by a dualism between nematic structure and polar forces, challenging conventional active nematic theories and highlighting these processes as major sources of entropy production.

Cluster percolation in the three-dimensional ±J\pm J random-bond Ising model

Using extensive parallel-tempering Monte Carlo simulations, this study reveals that in the three-dimensional ±J\pm J random-bond Ising model, a secondary percolation transition involving two equal-density clusters occurs above the thermodynamic ordering points, with the subsequent divergence of these cluster densities serving as a distinct percolation signature for the ferromagnetic and spin-glass phase transitions.

On the generalized Keffer form of the Dzyaloshinskii constant: its consequences for the spin, momentum and polarization evolution

This paper reviews and extends the generalized Keffer form of the Dzyaloshinskii constant by combining three known contributions and suggesting a fourth, analyzing their macroscopic consequences for spin, momentum, and polarization evolution while also proposing an analogous form for the exchange integral in symmetric Heisenberg Hamiltonians.
