Non-Markovian transients in transport across chiral quantum wires using space-time non-equilibrium Green functions
Nikhil Danny Babu, Girish S. Setlur
We study a system of two non-interacting quantum wires with fermions of opposite chirality with a point contact junction at the origin across which tunneling can take place when an…

Ponderous impurities in a Luttinger liquid
Joy Prakash Das, Girish S. Setlur
In this work, analytical expressions for the Green function of a Luttinger liquid are derived with one and two mobile impurities (heavy particles) using a combination of bosonizati…

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…
