C-BerryTrans: A C++ code for first-principles calculation of Berry-curvature-driven anomalous Hall and Nernst conductivities
Vivek Pandey, Sudhir K. Pandey
We present \textit{C-BerryTrans}, a C++ code for \textit{ab-initio} calculations of Berry-curvature-driven AHC \textit{i.e.}, and ANC \textit{i.e.}, .…
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…
Investigating the effect of electronic correlation on transport properties and phononic states of Vanadium
Prakash Pandey, Vivek Pandey, Sudhir K. Pandey
In the present work, we have tried to investigate the importance of electronic correlation on transport properties and phononic states of Vanadium (V). The temperature-dependent el…
Entanglement Meter: Estimation of entanglement with single copy in Interferometer
Som Kanjilal, Vivek Pandey, Arun Kumar Pati
Efficient certification and quantification of high dimensional entanglement of composite systems are challenging both theoretically as well as experimentally. Here, we demonstrate…
Capacity of Entanglement for Non-local Hamiltonian
Divyansh Shrimali, Swapnil Bhowmick, Vivek Pandey +1
The notion of capacity of entanglement is the quantum information theoretic counterpart of the heat capacity which is defined as the second cumulant of the entanglement spectrum. G…
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…
PY-Nodes: An ab-initio python code for searching nodes in a material using Nelder-Mead's simplex approach
Vivek Pandey, Sudhir K. Pandey
With the discovery of topological semimetals, it has been found that the band touching points near the Fermi level are of great importance. They give rise to many exciting phenomen…
