Three dimensional noncommutative bosonization
Rabin Banerjee, Subir Ghosh, T. Shreecharan
We consider the extension of the 2+1-dimensional bosonization process in Non-Commutative (NC) spacetime. We show that the large mass limit of the effective action obtained by integ…
Hawking radiation in GHS blackhole, Effective action and Covariant Boundary condition
Sunandan Gangopadhyay
We exploit the expression for the anomalous (chiral) effective action to obtain the Hawking radiation from the GHS (stringy) blackhole falling in the class of the most general sphe…
Quantum Cloning, Bell's Inequality and Teleportation
S. Adhikari, N. Ganguly, Indranil Chakrabarty +1
We analyze a possibility of using the two qubit output state from Buzek-Hillery quantum copying machine (not necessarily universal quantum cloning machine) as a teleportation chann…
Dynamics of cascade three-level system interacting with the classical and quantized field
Mihir Ranjan Nath, Surajit Sen, Gautam Gangopadhyay
We study the exact solutions of the cascade three-level atom interacting with a single mode classical and quantized field with different initial conditions of the atom. For the sem…
Strings in pp-wave background and background B-field from membrane and its symplectic quantization
Sunandan Gangopadhyay
The symplectic quantization technique is applied to open free membrane and strings in pp-wave background and background gauge field obtained by compactifying the open membrane in t…
Dynamical Transitions of a Driven Ising Interface
Manish K. Sahai, Surajit Sengupta
We study the structure of an interface in a three dimensional Ising system created by an external non-uniform field . changes sign over a two dimensional plane of…
