Thermal transport across a continuous metal-insulator transition
P. Haldar, M. S. Laad, S. R. Hassan
The celebrated Wiedemann-Franz (WF) law is believed to be robust in metals as long as interactions between electrons preserve their fermion-quasiparticle character. We study therma…
Quantum critical magneto-transport at a continuous metal-insulator transition
P. Haldar, M. S. Laad, S. R. Hassan +2
In contrast to the seminal weak localization prediction of a non-critical Hall constant () at the Anderson metal-insulator transition (MIT), in quite a few real diso…
Quantum critical transport at a continuous metal-insulator transition
P. Haldar, M. S. Laad, S. R. Hassan
In contrast to the first-order correlation-driven Mott metal-insulator transition (MIT), contin- uous disorder-driven transitions are intrinsically quantum critical. Here, we inves…
Real-space cluster dynamical mean-field approach to the Falicov-Kimball model: An alloy-analogy approach
P. Haldar, M. S. Laad, S. R. Hassan
It is long known that the best single-site coherent potential approximation (CPA) falls short of describing Anderson localization (AL). Here, we study a binary alloy disorder (or e…
