Order by Disorder and by Doping in Quantum Hall Valley Ferromagnets
Akshay Kumar, S. A. Parameswaran, S. L. Sondhi
We examine the Si(111) multi-valley quantum Hall system and show that it exhibits an exceptionally rich interplay of broken symmetries and quantum Hall ordering already near intege…
Order and disorder in SU(N) simplex solid antiferromagnets
Yury Yu. Kiselev, S. A. Parameswaran, Daniel P. Arovas
We study the structure of quantum ground states of simplex solid models, which are generalizations of the valence bond construction for quantum antiferromagnets originally proposed…
Quantum revivals and many-body localization
R. Vasseur, S. A. Parameswaran, J. E. Moore
We show that the magnetization of a single `qubit' spin weakly coupled to an otherwise isolated disordered spin chain exhibits periodic revivals in the localized regime, and retain…
