Intrinsic Orbital Nernst Effect in Real Photonic Bands
Tao Zhu
We predict an intrinsic orbital Nernst effect in reciprocal photonic lattices with real Bloch modes. In the collisionless regime, a thermal gradient generates a transverse angular-…
Ab initio design of enhanced and sign-reversible spin Hall and spin Nernst conductivity in skutterudite materials
Saikat Debnath, Babu Baijnath Prasad, Shishir Kumar Pandey
The search for novel materials capable of robust spin-current generation remains an active area of research. Here, we investigate the intrinsic spin Hall and spin Nernst effects in…
Pitfalls of Exchange-Correlation Functionals in Descriptions of Magnetism: Cautionary Tale of the FeRh Alloy
Shishir Kumar Pandey, Saikat Debnath, Zhanghao Zhouyina +1
The magnetic ground state of FeRh is highly sensitive towards the lattice constant. This, in addition to partially filled d-shells of Fe and Rh, posed a significant challenge for D…
Structural distortions in monolayers of binary semiconductors
Poonam Kumari, Saikat Debnath, Priya Mahadevan
We examine the structural properties of free standing II-VI and III-V semiconductors at the monolayer limit within first principle density functional theory calculations. A non-pol…
A high Neel temperature 5 oxide: NaOsO
S. Middey, Saikat Debnath, Priya Mahadevan +1
The origin of a high Neel temperature in a 5 oxide, NaOsO, has been analyzed within the mean-field limit of a multiband Hubbard model and compared with the analogous 4 ox…
Ultra-narrow and widely tunable Mn^(2+) Emission from Single Nanocrystals of ZnS-CdS alloy
Abhijit Hazarika, Arunasish Layek, Suman De +5
Extensively studied Mn-doped semiconductor nanocrystals have invariably exhibited photoluminescence (PL) over a narrow energy window of width <= 149 meV in the orange-red region an…
