Shift and spin vector: New topological quantum numbers for the Hall fluids.
  • Wen, Zee
  • Physics, Medicine
    Physical review letters
  • 10 August 1992
TLDR
The spin vectors are quantized and may be described picturesquely as a unification of electromagnetism and ``gravity'' in condensed-matter physics.
Classification of Abelian quantum Hall states and matrix formulation of topological fluids.
  • Wen, Zee
  • Physics, Medicine
    Physical review. B, Condensed matter
  • 15 July 1992
TLDR
It is shown that under certain mild assumptions the generalized hierarchy construction exhausts all possible Abelian fractional quantum Hall states and identifies and determines the topological quantity known as the shift.
Ground-state degeneracy of the fractional quantum Hall states in the presence of a random potential and on high-genus Riemann surfaces.
  • Wen, Niu
  • Physics, Medicine
    Physical review. B, Condensed matter
  • 1 May 1990
TLDR
The ground-state degeneracy provides a new quantum number in addition to the Hall conductance, characterizing different phases of the FQH systems, and the Ginzburg-Landau theory is a dual theory of the U(1) Chern-Simons topological theory.
Vacuum degeneracy of chiral spin states in compactified space.
  • Wen
  • Physics, Medicine
    Physical review. B, Condensed matter
  • 1 October 1989
TLDR
La dependance de la degenerescence du vide avec la topologie de l'espace reflete une espece de mise en ordre topologique dans l'etat de spin chiral.
Chiral Luttinger liquid and the edge excitations in the fractional quantum Hall states.
  • Wen
  • Physics, Medicine
    Physical review. B, Condensed matter
  • 15 June 1990
TLDR
The edge excitations are shown to form a new kind of state which is called the Chiral Luttinger Liquid (´LL), which clearly demonstrate the non-Fermi liquid behaviors of the FQH states.
Mean-field theory of spin-liquid states with finite energy gap and topological orders.
  • Wen
  • Physics, Medicine
    Physical review. B, Condensed matter
  • 1 August 1991
The mean-field theory of a T- and P-symmetric spin-liquid state is developed. The quasiparticle excitations in the spin-liquid state are shown to be spin-1/2 neutral fermions (the spinons) and charge
Chiral spin states and superconductivity.
  • Wen, Wilczek, Zee
  • Physics, Medicine
    Physical review. B, Condensed matter
  • 1 June 1989
TLDR
It is shown that several different order parameters can be used to characterize a type of P- and T-violating state for spin systems, that are called chiral-spin states, and speculated that superconducting states with unusual values of the flux quantum may exist.
Non-Abelian statistics in the fractional quantum Hall states.
  • Wen
  • Physics, Medicine
    Physical review letters
  • 11 February 1991
TLDR
The Fractional Quantum Hall states with non-Abelian statistics are studied and it is argued that the topological orders and the associated properties are robust against any kinds of small perturbations.
Sharp and smooth boundaries of quantum Hall liquids.
  • Chamon, Wen
  • Physics, Medicine
    Physical review. B, Condensed matter
  • 8 October 1993
TLDR
It is found that, for strong confining potentials, the edge of a $\nu=1$ liquid is described by the $Z_F=1 $ Fermi Liquid theory, even in the presence of interactions, a consequence of the chiral nature of the system.
Paired Hall state at half filling.
TLDR
Numerical experiments are presented, which provide evidence for several aspects of the theory, and the existence of a novel incompressible quantum liquid for spinless fermions at \ensuremath{\nu}=1/2 in the Hall effect is suggested.
