Compressibility as a probe of quantum phase transitions in topological superconductors
David Nozadze, Nandini Trivedi
The non-Abelian statistics of Majorana fermions, their role in topological quantum computation, and the possibility of realizing them in condensed matter systems, has attracted con…
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…
Quantum Griffiths singularities in ferromagnetic metals
David Nozadze, Thomas Vojta
We present a theory of the quantum Griffiths phases associated with the ferromagnetic quantum phase transition in disordered metals. For Ising spin symmetry, we study the dynamics…
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…
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…
