Orbital Ordering in FeMnVO: A First Principles Study
Dibyendu Dey, T. Maitra, A. Taraphder
Long range orbital order has been investigated in FeMnVO as a function of doping (x) using first principles density functional theory calculations including the…
Exciton condensation in an extended spinless Falicov Kimball model in the presence of orbital magnetic fields
S. Pradhan, A. Taraphder
An extended, spinless Falicov-Kimball model in the presence of perpendicular magnetic field is investigated employing Hartree-Fock self-consistent mean-field theory in two dimensio…
Mott transitions and Novel Orders in Multi-Orbital Models: The Relevance of Structural "Double Exchange"
Mukul S. Laad, S. Koley, A. Taraphder
In real transition-metal oxides, the so-called GdFeO3 octahedral tilt is long known to be a relevant control parameter influencing the range of orbital and magnetic ordered states…
Quantum critical dynamics of a magnetic impurity in a semiconducting host
Nagamalleswararao Dasari, Swagata Acharya, A. Taraphder +3
We have investigated the finite temperature dynamics of the singlet to doublet continuous quantum phase transition in the gapped Anderson impurity model using hybridization expansi…
Fermiology in a Local Quantum Critical Metal
Mukul S. Laad, S. Koley, A. Taraphder
Recent experimental work has brought the twin issues of the origin of non-Lifshitz-Kosevich scaling in de Haas van Alphen (dHvA) and its precise relation to anomalously broad non-q…
Orbital Effects of Strong Magnetic Field on a 2-D Holstein Polaron
S. Pradhan, Monodeep Chakraborty, A. Taraphder
We investigate the orbital effects of strong external magnetic field on the ground state properties of a two dimensional holstein polaron, employing variational approaches based on…
Emergent Quantum Coherence from Instabilities of a Perturbed Fractionalized Spin Liquid
Swagata Acharya, M. S. Laad, A. Taraphder
Effects of perturbations on topologically ordered (TO) states with fractionalized excitations is very intriguing. While small perturbations are not expected to affect a robust TO,…
