Anomalous Quantum Criticality at a Continuous Metal-Insulator Transition
M. S. Laad, Prosenjit Haldar
The Falicov-Kimball model (FKM) is long known to be the simplest model of correlated fermions exhibiting a novel Mott-like quantum critical point (QCP) assocaited with a {\it conti…
Quantum critical scaling of the conductivity tensor at the metal-insulator transition in NbTiN
D. Hazra, Prosenjit Haldar, M. S. Laad +12
In contrast to the Landau paradigm, a metal-insulator transition (MIT), driven purely by competition between itinerance and localization and unaccompanied by any conventional (e.g,…
Quench, thermalization and residual entropy across a non-Fermi liquid to Fermi liquid transition
Arijit Haldar, Prosenjit Haldar, Surajit Bera +2
We study the thermalization, after sudden and slow quenches, of an interacting model having a quantum phase transition from a Sachdev-Ye-Kitaev (SYK) non-Fermi liquid (NFL) to a Fe…
Universal dielectric response across a continuous metal-insulator transition
Prosenjit Haldar, M. S. Laad, S. R. Hassan
A wide range of disordered materials, including disordered correlated systems, show "Universal Dielectric Response" (UDR), followed by a superlinear power-law increase in their opt…
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…
