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…
Prethermalization and wave condensation in a nonlinear disordered Floquet system
Prosenjit Haldar, Sen Mu, Bertrand Georgeot +3
Periodically-driven quantum systems make it possible to reach stationary states with new emerging properties. However, this process is notoriously difficult in the presence of inte…
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…
