Quantum phase transition of the sub-Ohmic rotor model
Manal Al-Ali, Thomas Vojta
We investigate the behavior of an -component quantum rotor coupled to a bosonic dissipative bath having a sub-Ohmic spectral density with . With increasi…
Non-Fermi liquid transport and "universal" ratios in quantum Griffiths phases
David Nozadze, Thomas Vojta
We use the semi-classical Boltzmann equation to investigate transport properties such as electrical resistivity, thermal resistivity, thermopower, and the Peltier coefficient of di…
Infinite-randomness criticality in a randomly layered Heisenberg magnet
Fawaz Hrahsheh, Hatem Barghathi, Thomas Vojta
We study the ferromagnetic phase transition in a randomly layered Heisenberg magnet using large-scale Monte-Carlo simulations. Our results provide numerical evidence for the infini…
Transport properties in antiferromagnetic quantum Griffiths phases
David Nozadze, Thomas Vojta
We study the electrical resistivity in the quantum Griffiths phase associated with the antiferromagnetic quantum phase transition in a metal. The resistivity is calculated by means…
Composition-tuned smeared phase transitions
Fawaz Hrahsheh, David Nozadze, Thomas Vojta
Phase transitions in random systems are smeared if individual spatial regions can order independently of the bulk system. In this paper, we study such smeared phase transitions (bo…
