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…
