Pseudospin ferromagnetism in double-quantum-wire systems
D. -W. Wang, E. G. Mishchenko, E. Demler
We propose that a pseudospin ferromagnetic (i.e inter-wire coherent) state can exist in a system of two parallel wires of finite width in the presence of a perpendicular magnetic f…
Competing orders in thermally fluctuating superconductors in two dimensions
Subir Sachdev, Eugene Demler
We extend recent low temperature analyses of competing orders in the cuprate superconductors to the pseudogap regime where all orders are fluctuating. A universal continuum limit o…
Quantum phase transitions in the Bose-Fermi Kondo model
Gergely Zarand, Eugene Demler
We study quantum phase transitions in the Bose-Fermi Kondo problem, where a local spin is coupled to independent bosonic and fermionic degrees of freedom. Applying a second order e…
Competing orders in a magnetic field: spin and charge order in the cuprate superconductors
Ying Zhang, Eugene Demler, Subir Sachdev
We describe two-dimensional quantum spin fluctuations in a superconducting Abrikosov flux lattice induced by a magnetic field applied to a doped Mott insulator. Complete numerical…
Magnetic field tuning of charge and spin order in the cuprate superconductors
Anatoli Polkovnikov, Subir Sachdev, Matthias Vojta +1
Recent neutron scattering, nuclear magnetic resonance, and scanning tunneling microscopy experiments have yielded valuable new information on the interplay between charge and spin…
Quantitative Determination of a Microscopic Mechanism of High Tc Superconductivity
Eugene Demler, Shou-Cheng Zhang
Within the t-J model of copper-oxides, the condensation energy can be related to the change in the dynamical spin structure factor between the superconducting and the normal states…
