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…
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…
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…
Effect of oxygen vacancy on structural, electronic and magnetic properties of La-based oxide interfaces
Urmimala Dey, Swastika Chatterjee, A. Taraphder
Disorder, primarily in the form of oxygen vacancies, cation stoichiometry and atomic inter-diffusion, appear to play vital roles in the electronic and transport properties of the m…
Hidden Fermi Liquidity and Topological Criticality in the Finite Temperature Kitaev Model
Subhasree Pradhan, M. S. Laad, Avijeet Ray +2
The fate of exotic spin liquid states with fractionalized excitations at finite temperature () is of great interest, since signatures of fractionalization manifest in finite-tem…
Suppression of Hall number due to charge density wave order in high- cuprates
Gargee Sharma, S. Nandy, A. Taraphder +1
Understanding the pseudogap phase in hole-doped high temperature cuprate superconductors remains a central challenge in condensed matter physics. From a host of recent experiments…
