Bulk band inversion and surface Dirac cones in LaSb and LaBi : Prediction of a new topological heterostructure
Urmimala Dey, Monodeep Chakraborty, A. Taraphder +1
We perform \textit{ab initio} investigations of the bulk and surface band structures of LaSb and LaBi and resolve the existing disagreements about the topological property of LaSb,…
Metal-insulator transition in copper oxides induced by apex displacements
Swagata Acharya, Cedric Weber, Evgeny Plekhanov +3
High temperature superconductivity has been found in many kinds of compounds built from planes of Cu and O, separated by spacer layers. Understanding why critical temperatures are…
Planar Thermal Hall Effect in Weyl Semimetals
S. Nandy, A. Taraphder, Sumanta Tewari
Weyl semimetals are intriguing topological states of matter that support various anomalous magneto-transport phenomena. One such phenomenon is a negative longitudinal ($\mathbf{\na…
Holstein polarons and triplet bipolarons with NNN hopping
Monodeep Chakraborty, A. Taraphder, Mona Berciu
We study the ground state of 1D Holstein single polaron with next nearest neighbour electron hopping (NNN), employing a variational approximation based on exact diagonalization. Ou…
Berry phase theory of planar Hall effect in Topological Insulators
S. Nandy, A. Taraphder, Sumanta Tewari
Negative longitudinal magnetoresistance, in the presence of an external magnetic field parallel to the direction of an applied current, has recently been experimentally verified in…
Slave Rotor Approach to Exciton Condensation in a Two-band System
Subhasree Pradhan, A. Taraphder
Slave rotor mean field (SRMF) theory is employed to study exciton formation in the extended Falicov-Kimball Model (EFKM). In this theory, charge and spin (or orbital) degrees are t…
