Microscopic theory for electrocaloric effects in planar double layer systems
Rajeev Kumar, Jyoti P. Mahalik, Evgheni Strelcov +4
We present a field theory approach to study changes in local temperature due to an applied electric field (the electrocaloric effect) in electrolyte solutions. Steric effects and a…
Enhanced phase segregation induced by dipolar interactions in polymer blends
Rajeev Kumar, Bobby G. Sumpter, M. Muthukumar
We present a generalized theory for studying phase separation in blends of polymers containing dipoles on their backbone. The theory is used to construct co-existence curves and to…
Photocarrier relaxation in two-dimensional semiconductors
Daichi Kozawa, Rajeev Kumar, Alexandra Carvalho +8
Two-dimensional (2D) crystals of semiconducting transition metal dichalcogenides (TMD) absorb a large fraction of incident photons in the visible frequencies despite being atomical…
Novel discrete symmetries in the general N = 2 supersymmetric quantum mechanical model
R. Kumar, R. P. Malik
In addition to the usual supersymmetric (SUSY) continuous symmetry transformations for the general N = 2 SUSY quantum mechanical model, we show the existence of a set of novel disc…
Abelian p-Form (p = 1, 2, 3) Gauge Theories as the Field Theoretic Models for the Hodge Theory
R. Kumar, S. Krishna, A. Shukla +1
Taking the simple examples of an Abelian 1-form gauge theory in two (1 + 1)-dimensions, a 2-form gauge theory in four (3 + 1)-dimensions and a 3-form gauge theory in six (5 + 1)-di…
Dual-BRST symmetry: 6D Abelian 3-form gauge theory
R. Kumar, S. Krishna, A. Shukla +1
Within the framework of Becchi-Rouet-Stora-Tyutin (BRST) formalism, we demonstrate the existence of the novel off-shell nilpotent (anti-)dual-BRST symmetries in the context of a si…
