Coulomb interactions and delocalization in quantum Hall constrictions
Leonid P. Pryadko, Efrat Shimshoni, Assa Auerbach
We study a geometry-dependent effect of long-range Coulomb interactions on quantum Hall (QH) tunneling junctions. In an X-shaped geometry, duality relates junctions with opening an…
Superconductivity and Quantum Spin Disorder in Cuprates
Moshe Havilio, Assa Auerbach
A fundamental connection between superconductivity and quantum spin fluctuations in underdoped cuprates, is revealed. A variational calculation shows that {\em Cooper pair hopping}…
Projected SO(5) Models
Shou-Cheng Zhang, Jiang-Ping Hu, Enrico Arrigoni +2
We construct a class of projected SO(5) models where the Gutzwiller constraint of no-double-occupancy is implemented exactly. We introduce the concept of projected SO(5) symmetry w…
