Kalb-Ramond field interactions in a braneworld scenario
Ayan Chatterjee, Parthasarathi Majumdar
Electromagnetic and (linearized) gravitational interactions of the Kalb-Ramond (KR) field, derived from an underlying ten dimensional heterotic string in the zero slope limit, are…
Parity-violating Kalb-Ramond-Maxwell interactions and CMB anisotropy in a braneworld
Debaprasad Maity, Parthasarathi Majumdar, Soumitra SenGupta
Following up on a recent paper by two of us (DM and SS), demonstrating the large enhancement in observable optical activity in radiation from high redshift sources arising from the…
Black hole entropy: classical and quantum aspects
Parthasarathi Majumdar
An elementary introduction is given to the problem of black hole entropy as formulated by Bekenstein and Hawking, based on the so-called Laws of Black Hole Mechanics. Wheeler's `It…
Black hole entropy: certain quantum features
Parthasarathi Majumdar
The issue of black hole entropy is reexamined within a finite lattice framework along the lines of Wheeler, 't Hooft and Susskind, with an additional criterion to identify physical…
Does black hole radiance break supersymmetry ?
Parthasarathi Majumdar
Arguments presented in an earlier paper, demonstrating the breakdown of global supersymmetry in Hawking radiation from a generic four dimensional black hole with infalling massless…
Black Hole Radiance and Supersymmetry
Parthasarathi Majumdar
Starting with free massless scalar and spinor fields described by a globally N=1 supersymmetric action, infalling on a Schwarzschild black hole, the outgoing Hawking radiation is s…
