Broadening of a nonequilibrium phase transition by extended structural defects

Thomas Vojta

We study the effects of quenched extended impurities on nonequilibrium phase transitions in the directed percolation universality class. We show that these impurities have a dramat…

Exotic vs. conventional scaling and universality in a disordered bilayer quantum Heisenberg antiferromagnet

Rastko Sknepnek, Thomas Vojta, Matthias Vojta

We present large-scale Monte-Carlo simulations of a two-dimensional (2d) bilayer quantum Heisenberg antiferromagnet with random dimer dilution. In contrast to the exotic scaling sc…
