Monte Carlo simulations of a disordered superconductor-metal quantum phase transition
Ahmed K. Ibrahim, Thomas Vojta
We investigate the quantum phase transitions of a disordered nanowire from superconducting to metallic behavior by employing extensive Monte Carlo simulations. To this end, we map…
Monte Carlo simulations of the disordered three-color quantum Ashkin-Teller chain
Ahmed K. Ibrahim, Thomas Vojta
We investigate the zero-temperature quantum phase transitions of the disordered three-color quantum Ashkin-Teller spin chain by means of large-scale Monte Carlo simulations. We fin…
Emerging critical behavior at a first-order phase transition rounded by disorder
Ahmed K. Ibrahim, Thomas Vojta
We investigate the two-dimensional four-color Ashkin-Teller model by means of large-scale Monte-Carlo simulations. We demonstrate that the first-order phase transition of the clean…
Enhanced rare region effects in the contact process with long-range correlated disorder
Ahmed K. Ibrahim, Hatem Barghathi, Thomas Vojta
We investigate the nonequilibrium phase transition in the disordered contact process in the presence of long-range spatial disorder correlations. These correlations greatly increas…
