Light-driven Lifshitz transitions in non-Hermitian multi-Weyl semimetals
Debashree Chowdhury, Ayan Banerjee, Awadhesh Narayan
Non-Hermitian topological systems are the newest additions to the growing field of topological matter. In this work, we report of the light-driven exceptional physics in a multi-We…
Electron Condensation in a Jellium Coupled to a Finite Photonic Cavity
Pritha Mondal, Subham Kumar Saha, Awadhesh Narayan +1
We describe the process of electron condensation into a localized state in a structureless jellium that is coupled to a finite cavity. It is shown that there exists a temperature T…
Giant orbital polarization of Ni in square planar environment
Prithwijit Mandal, Ranjan Kumar Patel, Dibyata Rout +7
Understanding the electronic behavior of Ni in a square planar environment of oxygen is the key to unravel the origin of the recently discovered superconductivity in the hol…
Machine learning non-Hermitian topological phases
Brajesh Narayan, Awadhesh Narayan
Non-Hermitian topological phases have gained widespread interest due to their unconventional properties, which have no Hermitian counterparts. In this work, we propose to use machi…
Floquet Engineering of Multifold Fermions
Rimika Jaiswal, Awadhesh Narayan
Using Floquet theory, we investigate the effect of light on triple fold fermions. We study a low energy model as well as a simplified tight binding model under illumination. We fin…
Theoretical investigation of twin boundaries in WO: Structure, properties and implications for superconductivity
Noé Mascello, Nicola A. Spaldin, Awadhesh Narayan +1
We present a theoretical study of the structure and functionality of ferroelastic domain walls in tungsten trioxide, WO. WO has a rich structural phase diagram, with the st…
