Modification of smeared phase transitions by spatial disorder correlations
David Nozadze, Christopher Svoboda, Fawaz Hrahsheh +1
Phase transitions in disordered systems can be smeared if rare spatial regions develop true static order while the bulk system is in the disordered phase. Here, we study the effect…
Disordered bosons in one dimension: from weak to strong randomness criticality
Fawaz Hrahsheh, Thomas Vojta
We investigate the superfluid-insulator quantum phase transition of one-dimensional bosons with off-diagonal disorder by means of large-scale Monte-Carlo simulations. For weak diso…
Rounding of a first-order quantum phase transition to a strong-coupling critical point
Fawaz Hrahsheh, José A. Hoyos, Thomas Vojta
We investigate the effects of quenched disorder on first-order quantum phase transitions on the example of the -color quantum Ashkin-Teller model. By means of a strong-disorder…
Anomalous elasticity in a disordered layered XY model
Fawaz Hrahsheh, Thomas Vojta
We investigate the effects of layered quenched disorder on the behavior of planar magnets, superfluids, and superconductors by performing large-scale Monte-Carlo simulations of a t…
