C-BerryANC: A first-principle C++ code to calculate Berry Curvature dependent anomalous Nernst conductivity in any material

Vivek Pandey, Sudhir K. Pandey

The anomalous Nernst conductivity (ANC) is a key transport property in magnetic and topological materials, arising from the Berry curvature () of electronic bands. It…

: An python 3 code to calculate Berry Curvature dependent Anomalous Hall Conductivity in any material

Vivek Pandey, Sudhir K. Pandey

The anomalous Hall conductivity (AHC) in materials has long been a topic of debate. Studies reveal that AHC originates from the Berry curvature () of Bloch states. Ac…

An ab-initio study of nodal-arcs, axial strain's effect on nodal-lines & Weyl nodes and Weyl-contributed Seebeck coefficient in TaAs class of Weyl semimetals

Vivek Pandey, Sudhir K. Pandey

This work verifies the existence of dispersive \textit{nodal-arcs} and their evolution into Weyl nodes under the effect of spin-orbit coupling (SOC) in NbAs & NbP. The obtained fea…

Existence of nodal-arc and its evolution into Weyl-nodes in the presence of spin-orbit coupling in TaAs & TaP

Vivek Pandey, Sudhir K. Pandey

In this work, we report the existence of nodal-arc, which acts as the building block of all the nodal-rings in TaAs & TaP. This nodal-arc is found to be capable of generating all t…

Fundamental speed limits on entanglement dynamics of bipartite quantum systems

Vivek Pandey, Swapnil Bhowmick, Brij Mohan +2

The speed limits on entanglement are defined as the maximal rate at which entanglement can be generated or degraded in a physical process. We derive the speed limits on entanglemen…

Speed limits on correlations in bipartite quantum systems

Vivek Pandey, Divyansh Shrimali, Brij Mohan +2

Quantum speed limit is bound on the minimum time a quantum system requires to evolve from an initial state to final state under a given dynamical process. It sheds light on how fas…
