Effects of quasiparticle ambipolarity on the Nernst effect in underdoped cuprate superconductors
Sumanta Tewari, Chuanwei Zhang
We consider the Nernst effect in the normal state of the underdoped cuprate superconductors, where recent quantum oscillation experiments have indicated the existence of Fermi surf…
Realizing the strongly correlated -Mott state in a fermionic cold atom optical lattice
Michael R. Peterson, Chuanwei Zhang, Sumanta Tewari +1
We show that a new state of matter, the d-wave Mott-insulator state (d-Mott state) (introduced recently by [H. Yao, W. F. Tsai, and S. A. Kivelson, Phys. Rev. B 76, 161104 (2007)])…
Time-reversal symmetry breaking by a density-wave state in underdoped cuprate superconductors
Sumanta Tewari, Chuanwei Zhang, Victor M. Yakovenko +1
It was proposed that the density-wave state (DDW) may be responsible for the pseudogap behavior in the underdoped cuprates. Here we show that the admixture of a smal…
Goldstone modes and electromagnon fluctuations in the conical cycloid state of a multiferroic
Sumanta Tewari, Chuanwei Zhang, John Toner +1
Using a phenomenological Ginzburg-Landau theory for the magnetic conical cycloid state of a multiferroic, which has been recently reported in the cubic spinel CoCrO, we…
Testable signatures of quantum non-locality in a two-dimensional chiral p-wave superconductor
Sumanta Tewari, Chuanwei Zhang, S. Das Sarma +2
A class of topological excitations -- the odd-winding-number vortices -- in a spinless 2D chiral p-wave superconductor trap Majorana fermion states in the vortex cores…
Probing -Spin Correlations in Optical Lattices
Chuanwei Zhang, V. W. Scarola, S. Das Sarma
We propose a technique to measure multi-spin correlation functions of arbitrary range as determined by the ground states of spinful cold atoms in optical lattices. We show that an…
