Contour Integral Representations for the Characters of Logarithmic CFTs
Arjun Bagchi, Turbasu Biswas, Debashis Ghoshal
We propose a contour integral representation for the one-point correlators at genus one of the primaries of a family of rational logarithmic conformal field theories.
Canonical representation for electrons and its application to the Hubbard model
Brijesh Kumar
A new representation for electrons is introduced, in which the electron operators are written in terms of a spinless fermion and the Pauli operators. This representation is canonic…
Observation of Ultra-narrow Electromagnetically Induced Transparency and Slow Light using Purely Electronic Spins in a Hot Atomic Vapor
F. Goldfarb, J. Ghosh, M. David +6
Electromagnetically induced transparency (EIT) is observed in gaseous 4He at room temperature. Ultra-narrow (less than 10 kHz) EIT windows are obtained for the first time for purel…
Glassy Aging with Modified Kohlrausch-Williams-Watts Form
Bhaskar Sen Gupta, Shankar P. Das
In this report we address the question whether aging in the non equilibrium glassy state is controlled by the equilibrium alpha-relaxation process which occur at temperatures above…
