Enhanced crystal-field splitting and orbital-selective coherence induced by strong correlations in

…, AI Lichtenstein, AN Rubtsov, T Saha-Dasgupta… - Physical Review B, 2007 - APS
We present a study of the paramagnetic metallic and insulating phases of vanadium sesquioxide
by means of the N th order muffin-tin orbital implementation of density functional theory …

Orbital-selective superconductivity in a two-band model of infinite-layer nickelates

…, T Das, I Dasgupta, T Saha-Dasgupta - Physical Review B, 2020 - APS
In the present Rapid Communication, we explore superconductivity in Nd Ni O 2 and La Ni
O 2 employing a first-principles derived low-energy model Hamiltonian, consisting of two …

Multistep approach to microscopic models for frustrated quantum magnets: The case of the natural mineral azurite

…, H Kandpal, R Valentí, H Das, T Saha-Dasgupta… - Physical Review Letters, 2011 - APS
The natural mineral azurite Cu 3 (CO 3) 2 (OH) 2 is a frustrated magnet displaying unusual
and controversially discussed magnetic behavior. Motivated by the lack of a unified …

XY magnetism, Kitaev exchange, and long-range frustration in the honeycomb cobaltates

S Das, S Voleti, T Saha-Dasgupta, A Paramekanti - Physical Review B, 2021 - APS
The quest for Kitaev quantum spin liquids has led to great interest in honeycomb quantum
magnets with strong spin-orbit coupling. It has been recently proposed that even Mott …

Band-Structure Trend in Hole-Doped Cuprates and Correlation with

E Pavarini, I Dasgupta, T Saha-Dasgupta, O Jepsen… - Physical review …, 2001 - APS
By calculation and analysis of the bare conduction bands in a large number of hole-doped
high-temperature superconductors, we have identified the range of the intralayer hopping as …

Electronic structure of and quantum size effect in III-V and II-VI semiconducting nanocrystals using a realistic tight binding approach

R Viswanatha, S Sapra, T Saha-Dasgupta, DD Sarma - Physical Review B, 2005 - APS
We analyze the electronic structure of group III-V semiconductors obtained within full
potential linearized augmented plane wave (FP-LAPW) method and arrive at a realistic and …

Electronic Structure of

DD Sarma, P Mahadevan, T Saha-Dasgupta, S Ray… - Physical review …, 2000 - APS
We have analyzed the unusual electronic structure of Sr 2 FeMoO 6 combining ab initio and
model Hamiltonian approaches. Our results indicate that there are strong enhancements of …

Muffin-tin orbitals of arbitrary order

OK Andersen, T Saha-Dasgupta - Physical Review B, 2000 - APS
We have derived orbital basis sets from scattering theory. They are expressed as polynomial
approximations to the energy dependence of a set of partial waves, in quantized form. The …

Manipulating the mechanical properties of MXene: Effect of substitutional doping

…, T Das, D Nafday, L Boeri, T Saha-Dasgupta - Physical Review B, 2017 - APS
With the aim of manipulating the mechanical properties of the recently discussed two-dimensional
material MXene, we investigate the effect of alloying. We consider substitutional …

Double perovskites with 3d and 4d/5d transition metals: compounds with promises

T Saha-Dasgupta - Materials Research Express, 2020 - iopscience.iop.org
Double perovskites, which can host two different transition metal cations at the B-sites of its
perovskite derived structure, provide the possibility to explore the interplay of localized 3d …
