Quantum Critical Phase and Lifshitz Transition in an Extended Periodic Anderson Model
M. S. Laad, S. Koley, A Taraphder
We study the quantum phase transition in -electron systems as a quantum Lifshitz transition driven by selective Mott localization in a realistic extended Anderson lattice model.…
An extended Falicov-Kimball model on a triangular lattice
Umesh K. Yadav, T. Maitra, Ishwar Singh +1
The combined effect of frustration and correlation in electrons is a matter of considerable interest of late. In this context a Falicov-Kimball model on a triangular lattice with t…
Preformed excitonic liquid route to a charge density wave in 2H-TaSe
A. Taraphder, S. Koley, N. S. Vidhyadhiraja +1
Recent experiments on 2H-TaSe contradict the long-held view of the charge density wave arising from a nested band structure. An intrinsically strong coupling view, involving a…
On the question of metallicity and ferromagnetism in charge ordered insulating Nd0.5Sr0.5MnO3 nanoparticles
S. Kundu, T. K. Nath, A. K. Nigam +2
The fascinating phenomenon of destabilization of charge/orbital order in Nd0.5Sr0.5MnO3 with the reduction of grain size is critically investigated. Based on our magnetic and trans…
Field dependent dynamics in the metallic regime of the half-filled Hubbard model
D. Parihari, N. S. Vidhyadhiraja, A. Taraphder
A systematic study of the effect of magnetic field (h) on Hubbard model has been carried out at half filling within dynamical mean field theory. In agreement with previous studies,…
Ground state phase diagram of a spinless, extended Falicov-Kimball model on the triangular lattice
Umesh K. Yadav, T. Maitra, Ishwar Singh +1
Correlated systems with hexagonal layered structures have come to fore with renewed interest in Cobaltates, transition-metal dichalcogenides and GdI2. While superconductivity, unus…
