Thermodynamic Geometry and Extremal Black Holes in String Theory
Tapobrata Sarkar, Gautam Sengupta, Bhupendra Nath Tiwari
We study a generalisation of thermodynamic geometry to degenerate quantum ground states at zero temperatures exemplified by charged extremal black holes in type II string theories.…

Some Aspects of Scattering in (Non) Commutative Gauge Theories
Zafar Ahmed, Tapobrata Sarkar
We study almost-forward scattering in the context of usual and non-commutative QED. We study the semi-classical behaviour of particles undergoing this scattering process in the two…

The asymptotic behaviour of in the double scaling limit
Tapobrata Sarkar, Rahul Basu
In the kinematic region of small and large in deep inelastic scattering, presently being explored by HERA, we present an analysis of the evolution of the longitudinal str…
