No sliding in time
Kirill Shtengel, Chetan Nayak, Waheb Bishara +1
In this letter, we analyse the following apparent paradox: As has been recently proved by Hastings (cond-mat/0305505), under a general set of conditions, if a local Hamiltonian has…
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…
An extended Hubbard model with ring exchange: a route to a non-Abelian topological phase
Michael Freedman, Chetan Nayak, Kirill Shtengel
We propose an extended Hubbard model on a 2D Kagome lattice with an additional ring-exchange term. The particles can be either bosons or spinless fermions . At a special filling fr…
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…
Non-Abelian topological phases in an extended Hubbard model
Michael Freedman, Chetan Nayak, Kirill Shtengel
We describe four closely related Hubbard-like models (models A, B, C and D) of particles that can hop on a 2D Kagome lattice interacting via Coulomb repulsion. The particles can be…
