Random-strain-induced correlations in materials with intertwined nematic and magnetic orders
W. Joe Meese, Thomas Vojta, Rafael M. Fernandes
Electronic nematicity is rarely observed as an isolated instability of a correlated electron system. Instead, in iron pnictides and in certain cuprates and heavy-fermion materials,…
Stripe order, impurities, and symmetry breaking in a diluted frustrated magnet
Xuecheng Ye, Rajesh Narayanan, Thomas Vojta
We investigate the behavior of the frustrated - Ising model on a square lattice under the influence of random dilution and spatial anisotropies. Spinless impurities gener…
Tempered fractional Brownian motion on finite intervals
Thomas Vojta, Zachary Miller, Samuel Halladay
Diffusive transport in many complex systems features a crossover between anomalous diffusion at short times and normal diffusion at long times. This behavior can be mathematically…
Localization of the Higgs mode at the superfluid-Mott glass transition
Jack Crewse, Thomas Vojta
The amplitude (Higgs) mode near the two-dimensional superfluid-Mott glass quantum phase transition is studied. We map the Bose-Hubbard Hamiltonian of disordered interacting bosons…
Signatures of a Quantum Griffiths Phase close to an Electronic Nematic Quantum Phase Transition
Pascal Reiss, David Graf, Amir A. Haghighirad +2
In the vicinity of a quantum critical point, quenched disorder can lead to a quantum Griffiths phase, accompanied by an exotic power-law scaling with a continuously varying dynamic…
Green's functions on a renormalized lattice: An improved method for the integer quantum Hall transition
Martin Puschmann, Thomas Vojta
We introduce a performance-optimized method to simulate localization problems on bipartite tight-binding lattices. It combines an exact renormalization group step to reduce the spa…
