Ferroelastic exciton splitting in hybrid perovskite nanowalls
Afreen, J. Delgado-Alvarez, H. Krishna Mishra +9
Hybrid metal-halide perovskites are soft semiconductors in which electronic excitations are strongly influenced by lattice distortions and structural phase transitions. An importan…
Spin orientation -- a subtle interplay between strain and multipole Coulomb interactions
Subhra Sen Gupta, Shinjini Paul, Suman Mandal +2
We address the technologically important issue of the spin orientation on a correlated magnetic surface and how to manipulate it. We consider a prototypical strongly correlated sys…
Detection of nontrivial topology driven by charge density wave in a semi-Dirac metal
Rafiqul Alam, Prasun Boyal, Shubhankar Roy +6
The presence of electron correlations in a system with topological order can lead to exotic ground states. Considering single crystals of LaAgSb2 which has a square net crystal str…
Hole doping in a negative charge transfer insulator
Ranjan Kumar Patel, Krishnendu Patra, Shashank Kumar Ojha +7
NiO is a negative charge transfer energy system and exhibits a temperature-driven metal-insulator transition (MIT), which is also accompanied by a bond disproportionation (…
Microscopic Origin Of Room Temperature Ferromagnetism in a Double Perovskite SrFeReO: a first principle and model Hamiltonian study
Shishir K. Pandey, Ashis K. Nandy, Poonam Kumari +1
The puzzling observation of room temperature ferromagnetism in double perovskites (ABBO), despite having the magnetic lattice of B-ions diluted by non-magnetic B-ions…
Diffusion Monte Carlo Study on Relative Stabilities of Boron Nitride Polymorphs
Yutaka Nikaido, Tom Ichibha, Kenta Hongo +5
Although Boron nitride (BN) is a well-known compound widely used for engineering and scientific purposes, the phase stability of its polymorphs, one of its most fundamental propert…
