Monte Carlo study of the critical properties of the three-dimensional 120-degree model
Sandro Wenzel, Andreas M. Laeuchli
We report on large scale finite-temperature Monte Carlo simulations of the classical or orbital-only model on the simple cubic lattice in three dimensions with a…
Selectively increasing the diversity of GAN-generated samples
Jan DubiÅski, Kamil Deja, Sandro Wenzel +2
Generative Adversarial Networks (GANs) are powerful models able to synthesize data samples closely resembling the distribution of real data, yet the diversity of those generated sa…
Kertesz Line in the Three-Dimensional Compact U(1) Lattice Higgs Model
Sandro Wenzel, Elmar Bittner, Wolfhard Janke +2
The three-dimensional lattice Higgs model with compact U(1) gauge symmetry and unit charge is investigated by means of Monte Carlo simulations. The full model with fluctuating Higg…
Re-examining the directional-ordering transition in the compass model with screw-periodic boundary conditions
Sandro Wenzel, Wolfhard Janke, Andreas M. Laeuchli
We study the directional-ordering transition in the two-dimensional classical and quantum compass models on the square lattice by means of Monte Carlo simulations. An improved algo…
Finite-Temperature Néel Ordering of Fluctuations in a Plaquette Orbital Model
Sandro Wenzel, Wolfhard Janke
We present a pseudospin model which should be experimentally accessible using solid-state devices and, being a variation on the compass model, adds to the toolbox for the protectio…
Evidence of columnar order in the fully frustrated transverse field Ising model on the square lattice
Sandro Wenzel, Tommaso Coletta, Sergey E. Korshunov +1
Using extensive classical and quantum Monte Carlo simulations, we investigate the ground-state phase diagram of the fully frustrated transverse field Ising model on the square latt…
