Orbital Magnetism in the Cuprates
Sudip Chakravarty, Hae-Young Kee, Chetan Nayak
The pseudogap phase of the cuprate superconductors is argued to be characterized by a hidden broken symmetry of d-wave character in the particle-hole channel that leads to staggere…
Electrical and Thermal Transport by Nodal Quasiparticles in the DDW State
Xiao Yang, Chetan Nayak
We compute the electrical and thermal conductivities and Hall conductivities of the -density wave (DDW) state in the low-temperature impurity-scattering-dominated regime for low…
On the Current Carried by `Neutral' Quasiparticles
Chetan Nayak, Kirill Shtengel, Dror Orgad +2
The current should be proportional to the momentum in a Galilean-invariant system of particles of fixed charge-to-mass ratio, such as an electron liquid in jellium. However, strong…
Fractionalization patterns in strongly correlated electron systems: Spin-charge separation and beyond
Eugene Demler, Chetan Nayak, Hae-Young Kee +2
We discuss possible patterns of electron fractionalization in strongly interacting electron systems. A popular possibility is one in which the charge of the electron has been liber…
Neutron Scattering Signature of d-density Wave Order in the Cuprates
Sudip Chakravarty, Hae-Young Kee, Chetan Nayak
An ordered -density wave (DDW) state has been proposed as an explanation of the pseudogap phase in underdoped high-temperature superconductors. The staggered currents associated…
Spin and Current Correlation Functions in the \bf d-density Wave State of the Cuprates
Sumanta Tewari, Hae-Young Kee, Chetan Nayak +1
We calculate the spin-spin and current-current correlation functions in states exhibiting d_{{x^2}-{y^2}}-density wave (DDW) order, d_{{x^2}-{y^2}} superconducting order (DSC), or…
