Screening in anisotropic superfluids and the superfluid density in underdoped cuprates
Matthew J. Case, Igor F. Herbut
We examine the nature of the collective excitations in a strongly anisotropic system of bosons interacting via Coulomb interaction. Such a system has often been used in the past to…
Chiral symmetry breaking in in presence of irrelevant interactions: a renormalization group study
Kamran Kaveh, Igor F. Herbut
Motivated by recent theoretical approaches to high temperature superconductivity, we study dynamical mass generation in three dimensional quantum electrodynamics ) i…
Effective theory of high-temperature superconductors
Igor F. Herbut
General field theory of a fluctuating d-wave superconductor is constructed and proposed as an effective description of superconducting cuprates at low energies. The theory is used…
Finite temperature superfluid density in very underdoped cuprates
Igor F. Herbut, Matthew J. Case
The combination of a large superconducting gap, low transition temperature, and quasi two-dimensionality in strongly underdoped high temperature superconductors severely constrains…
Theory of spin response in underdoped cuprates as strongly fluctuating d-wave superconductors
Igor F. Herbut, Dominic J. Lee
We study the spin dynamics in underdoped cuprates at low temperatures by considering them as quasi two dimensional d-wave superconductors (dSC) with strong phase fluctuations. An e…
Spin-charge separation and recombination in quantum disordered d-wave superconductors
Igor F. Herbut
Some of the results of this paper have been superseded in the meantime. See, cond-mat/0410557.
