Electric-field induced trends of exchange interactions in transition-metal trilayers
Moinak Ghosh, Stefan Heinze, Souvik Paul
Using density functional theory, we have performed a systematic study of the Heisenberg pairwise exchange interaction and the beyond Heisenberg multi-spin higher-order exchange int…
Electric-field driven stability control of skyrmions in an ultrathin transition-metal film
Souvik Paul, Stefan Heinze
To realize future spintronic applications with magnetic skyrmions -- topologically nontrivial swirling spin structures -- it is essential to achieve efficient writing and deleting…
Effect of magnetic field on jet transport coefficient
Debjani Banerjee, Prottoy Das, Souvik Paul +4
We report the estimation of jet transport coefficient, for quark- and gluon-initiated jets using a simple quasi-particle model in absence and presence of magnetic field.…
Stacking-dependent spin interactions in Pd/Fe bilayers on Re(0001)
W. Li, S. Paul, K. von Bergmann +2
Using spin-polarized scanning tunneling microscopy and density functional theory, we have studied the magnetic properties of Pd/Fe atomic bilayers on Re(0001). Two kinds of magneti…
Collisional time and shear relaxation time for interacting QGP
Ankit Anand, Souvik Paul, Sarthak Satapathy +1
We have studied the collisional time and relaxation time of a QGP(Quark-Gluon Plasma) by parameterizing them by temperature. From this parameterization we have obtained the decay r…
Mapping QGP interaction through its temperature dependent degeneracy factor
Ranjesh Kumar, Ankit Anand, Souvik Paul +2
We have parameterized the degeneracy factor in terms of temperature and using this we have tried to compare and study the LQCD(Lattice Quantum Chromodynamics) data with our data.
Role of interaction on electrical conductivity of QGP in presence of magnetic field
Ankita Mishra, Souvik Paul, Jayanta Dey +2
Effect of quantum chromodynamics (QCD) interaction in quark-gluon plasma on electrical conductivity is studied, where lattice quantum chromodynamics (LQCD) results are mapped throu…

Souvik Paul, Ankita Mishra, Jayanta Dey +2
Fluidity of quark-gluon plasma (QGP) is studied where interaction between quark and gluon is mapped through fugacity in particle distribution function using lattice quantum chromod…
Role of higher-order exchange interactions for skyrmion stability
Souvik Paul, Soumyajyoti Haldar, Stephan von Malottki +1
Transition-metal interfaces and multilayers are a very promising class of systems to realize nanometer-sized, stable magnetic skyrmions for future spintronic devices. For room temp…
Tailoring magnetic interactions in atomic bilayers of Rh and Fe on Re(0001)
Souvik Paul, Stefan Heinze
Using density functional theory, we investigate the interplay between the stacking order and sequence of bilayers composed of an Fe and a Rh layer on the Re(0001) and their magneti…

Jayanta Dey, Sarthak Satapathy, Ankita Mishra +2
We have attempted to build a parametric based simplified and analytical model to map the interaction of quarks and gluons in presence of magnetic field, which has been constrained…
Playing Quantum Monty Hall Game in a Quantum Computer
Souvik Paul, Bikash K. Behera, Prasanta K. Panigrahi
Here, we present the quantum version of a very famous statistical decision problem, whose classical version is counter-intuitive to many. The Monty Hall game can be phrased as a tw…
