Incommensurate DDW order
Ivailo Dimov, Chetan Nayak
We consider various incommensurate (IC) order parameters for electrons on a square lattice which reduce to -density wave (DDW) order when the ordering wavevector ${\bf…
Proposal to stabilize and detect half-quantum vortices in strontium ruthenate thin films: Non-Abelian braiding statistics of vortex matter in a superconductor
Sankar Das Sarma, Chetan Nayak, Sumanta Tewari
We propose a simple way to stabilize half-quantum vortices in superconducting strontium ruthenate, assuming the order parameter is of chiral symmetry, as is suggested…
Downward shift of infrared conductivity spectral weight at the DDW transition: role of anisotropy
Rouzbeh Gerami, Chetan Nayak
We consider the motion of conductivity spectral weight at a finite-temperature phase transition at which density-wave (DDW) order develops. We show that there is a sh…
Fourier Transformed Scanning Tunneling Peaks in the -density wave phase
Cristina Bena, Sudip Chakravarty, Jiangping Hu +1
In this brief note we repeat an earlier calculation of the Fourier transformed scanning tunneling spectra of the -density wave (DDW) phase using a different band structure, whic…
Quasiparticle scattering and local density of states in the d-density wave phase
Cristina Bena, Sudip Chakravarty, Jiangping Hu +1
We study the effects of single-impurity scattering on the local density of states in the high- cuprates. We compare the quasiparticle interference patterns in three different…
Infrared Hall angle in the -density wave state: a comparison of theory and experiment
Sumanta Tewari, Sudip Chakravarty, John Ove Fjaerestad +2
Infrared Hall measurements in the pseudogap phase of the high- cuprates are addressed within the framework of the ordered -density wave state. The zero-temperature Hall fre…
