Emergent Pair Density Wave and Incoherent Metallic State in a Strongly Correlated Doped System
Soham Maiti, Nandan Pakhira, A. Taraphder
We investigate the dynamical emergence of a state driven by the interplay between antiferromagnetism (AFM) and singlet -wave superconductivity (SC) within a slave-rotor mean-fie…
Electronic properties of magnetic semiconductor : a first principles study
Apurba Sarkar, Joydeep Chatterjee, Arghya Taraphder +1
Geometrically frustrated magnetic semiconductor has potential applications as photo-catalyst, in photochemical cells and multi-ferroic devices. Electronic band…
Role of strong correlation and spin-orbit coupling in : a first principle study
Ismail Sk, Joydeep Chatterjee, A. Taraphder +1
The recent observation of magnetization plateaus in rare-earth metallic tetraborides has drawn a lot of attention to this class of materials. In this work, we investigate the elect…
Role of work function distribution on field emission effects
Nandan Pakhira, Rajib Mahato
Field emission effect is the emission of electrons from a cold metallic surface in the presence of an electric field. The emission current exponentially depends on the work functio…
Role of spin-orbit coupling effects in rare-earth metallic tetra-borides : a first principle study
Ismail Sk, Nandan Pakhira
We have investigated the electronic structure of rare-earth tetraborides, , using first-principle electronic structure methods (DFT) implemented in Quantum Espress…
X-Ray Photoemission Spectroscopy in the Falicov-Kimball model
Nandan Pakhira, A. M. Shvaika, J. K. Freericks
We calculate the finite temperature X-ray photoemission spectroscopy for the Falicov-Kimball model using a Weiner-Hopf sum equation approach. In the metallic state, the core-hole s…
Electronic structure of metallic tetra-boride : An LDA+DMFT study
Nandan Pakhira, Jyoti Krishna, S. Nandy +2
Recent experimental observations of magnetization plateau in metallic tetraboride have created a lot of interest in these class of materials. Hysteretic longitud…
Shear viscosity of strongly interacting fermionic quantum fluids
Nandan Pakhira, Ross H. McKenzie
Eighty years ago Eyring proposed that the shear viscosity of a liquid, , has a quantum limit where is the density of the fluid. Using holographic duality a…
Absence of a quantum limit to charge diffusion in bad metals
Nandan Pakhira, Ross H. McKenzie
Good metals are characterised by diffusive transport of coherent quasi-particle states and the resistivity is much less than the Mott-Ioffe-Regel (MIR) limit, , w…
Resonant inelastic X-ray scattering in a Mott insulator
Nandan Pakhira, J. K. Freericks, A. M. Shvaika
We calculate the resonant inelastic X-ray scattering (RIXS) response in a Mott insulator which is described by the Falicov-Kimball model. The model can be solved exactly within the…
Unusual doping and temperature dependence of photoemission spectra from manganites
Prabuddha Sanyal, Subhra Sen Gupta, Nandan Pakhira +3
A recent, major, puzzle in the core-level photoemission spectra of doped manganites is the observation of a 1-2 eV wide shoulder with intensity varying with temperature T as the sq…
