Renormalization group study of the Kondo problem at a junction of several Luttinger wires
V. Ravi Chandra, Sumathi Rao, Diptiman Sen
We study a system consisting of a junction of N quantum wires, where the junction is characterized by a scalar S-matrix, and an impurity spin is coupled to the electrons close to t…
A multi-channel fixed point for a Kondo spin coupled to a junction of Luttinger liquids
V. Ravi Chandra, Sumathi Rao, Diptiman Sen
We study a system of an impurity spin coupled to a junction of several Tomonaga-Luttinger liquids using a renormalization group scheme. For the decoupled S-matrix at the junction,…
Intra-night Optical Variability of Luminous Radio Quiet QSOs
A. C. Gupta, U. C. Joshi
In the present paper we report the detection of intra-night variability in some of the RQQSOs and one LDQ. To study intra-night variability, we carried out photometric monitoring o…
A Novel Non-Fermi Liquid Ground State in One Dimension
Girish S. Setlur, HRI
We propose a new non-Fermi liquid ground state in one dimension that is not of the Luttinger type. It is the ground state of fermions interacting via a long range repulsive interac…
