Renormalization Group Approach to Strong-Coupled Superconductors
S. -W. Tsai, A. H. Castro Neto, R. Shankar +1
We develop an asymptotically exact renormalization group (RG) approach that treats electron-electron and electron-phonon interactions on equal footing. The approach allows an unbia…
Spiral orientational order in quantum Hall skyrmion lattices
Sumithra Sankararaman, R. Shankar
We investigate the existence of spiral ordering in the planar spin orientation of skyrmions localised on a face centered rectangular lattice (FCRL). We use the non-linear sigma mod…
Luttinger revisted-the renormalization group approach
R. Shankar
Luttinger's contributions abound in different parts of many-body physics. Here I review the ones that appear when one uses the Renormalization Group (RG) to study the subject: the…
Gauge Invariant Bosonization of Quantum Hall Systems and Skyrmions : Kinematics
Sreedhar B. Dutta, R. Shankar
We develop a systematic semiclassical approximation scheme for quantum Hall skyrmions near filling factors , which is exact in the long wavelength limit. We cons…
