Kaluza-Klein Gravitons in a Higher Curvature Warped Geometry : A New Perspective
Abhirup Karmakar, Isika Mandal, Soumitra SenGupta
Kaluza-Klein (KK) Gravitons are the direct collider imprints of the higher dimensional bulk physics in our four dimensional universe, arising from the compactification of an extra…

Tachyonic (In)stability in Randall-Sundrum Braneworld Scenarios
Abhirup Karmakar, Soumitra SenGupta
Low-energy effective theories provide a natural description of four-dimensional physics in higher-dimensional geometries, where the imprint of the bulk geometry appears as paramete…

Relativistic Dynamics and Electron Transport in Isolated Chiral Molecules
Sushant Kumar Behera, Ruggero Sala, Abhirup Roy Karmakar +3
The Chirality-Induced Spin Selectivity (CISS) effect describes the ability of chiral molecules and crystals to transmit spin-polarized currents, a phenomenon first identified in 19…
