Pinned Bilayer Wigner Crystals with Pseudospin Magnetism
Yong P. Chen
We study a model of \textit{pinned} bilayer Wigner crystals (WC) and focus on the effects of interlayer coherence (IC) on pinning. We consider both a pseudospin ferromagnetic WC (F…
Ferromagnetism of the Hubbard Model at Strong Coupling in the Hartree-Fock Approximation
Volker Bach, Elliott H. Lieb, Marcos V. Travaglia
As a contribution to the study of Hartree-Fock theory we prove rigorously that the Hartree-Fock approximation to the ground state of the d-dimensional Hubbard model leads to satura…
Flux expulsion and greedy bosons: frustrated magnets at large N
O. Tchernyshyov, R. Moessner, S. L. Sondhi
We investigate the Sp(N) mean-field theory for frustrated quantum magnets. First, we establish some general properties of its solutions; in particular, for small spin we propose si…
Evidence for Two Different Solid Phases of Two Dimensional Electrons in High Magnetic Fields
Yong P. Chen, R. M. Lewis, L. W. Engel +5
We have performed RF spectroscopy on very high quality two dimensional electron systems in the high magnetic field insulating phase, usually associated with a Wigner solid (WS) pin…
Dependence of spin susceptibility of a two-dimensional electron system on the valley degree of freedom
Y. P. Shkolnikov, K. Vakili, E. P. De Poortere +1
We report measurements of the spin susceptibility, , in an AlAs two-dimensional electron system where, via the application of in-plane stress, we transfer elec…
Formation of Electronic Nematic Phase in Interacting Systems
Igor Khavkine, Chung-Hou Chung, Vadim Oganesyan +1
We study the formation of an electronic nematic phase characterized by a broken point-group symmetry in interacting fermion systems within the weak coupling theory. As a function o…
