Plaquette Resonating-Valence-Bond Ground State of CaVO
Kazuo Ueda, Hiroshi Kontani, Manfred Sigrist +1
A theoretical model is presented to explain the spin gap observed for CaVO. The underlying lattice of the 1/5-depleted square lattice favors a formation of plaquette resona…
Random Quantum Spin Chains: A Real-Space Renormalization Group Study
E. Westerberg, A. Furusaki, M. Sigrist +1
Quantum Heisenberg spin chains with random couplings and spin sizes are studied using a real-space renormalization group technique. These systems belong to a new universality class…
Theory of Underdoped Cuprates
Xiao-Gang Wen, Patrick A. Lee
We develop a slave-boson theory for the t-J model at finite doping which respects an SU(2) symmetry -- a symmetry previously known to be important at half filling. The mean field p…
Quantum Boltzmann equation of composite fermions interacting with a gauge field
Yong Baek Kim, Patrick A. Lee, Xiao-Gang Wen
We derive the quantum Boltzmann equation (QBE) of composite fermions at/near the state using the non-equilibrium Green's function technique. The lowest order perturbative…
Theory of the half-filled Landau level
N. Read
A recent theory of a compressible Fermi-liquid like state at Landau level filling factors or , even, is reviewed, with emphasis on the basic physical concepts.
Energy Gap Structure in Bilayer Oxide Superconductors
Kazuhiro Kuboki, Patrick A. Lee
We consider a model for bilayer superconductors where an interlayer pairing amplitude co-exists with intralayer pairing of symmetry. This model is…
