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…
Strange-like Metallicity in a Toy Model with Selective-Mottness
M. S. Laad, S. R. Hassan
The interplay between band and atomic aspects in materials with co-existing wide-band and flat-band states, or wide-band and effectively dispersionless electronic states is increas…
Intricately Entangled Spin and Charge Diffusion and the Coherence-Incoherence Crossover in the High-Dimensional Hubbard Model
Gopal Prakash, S. R. Hassan, M. S. Laad +2
Correlation-driven metal-insulator transitions and temperature-driven quantum-coherent-to-incoherent crossovers in correlated electron systems underpin the doping, temperature and…
A Tale of Two Quantum Compass Models
Soumya Sur, M. S. Laad, Arya Subramonian +1
We investigate two variants of quantum compass models (QCMs). The first, an orbital-only honeycomb QCM, is shown to exhibit a quantum phase transition (QPT) from a - to -or…
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,…
Fascinating interplay between Charge Density Wave Order and magnetic field in Non-magnetic Rare-Earth Tritelluride LaTe
Arnab Pariari, Sudipta Koley, Shubhankar Roy +4
Charge density wave (CDW) states in solids bear an intimate connection to underlying fermiology. Modification of the latter by a suitable perturbation provides an attractive handle…
