Journal ArticleDOI
Squeezed strings and Yangian symmetry of the Heisenberg chain with long-range interaction.
Z. N. C. Ha,Frederick D. Haldane +1 more
TL;DR: The exact and complete set of highest-weight eigenstates of the finite-size SU(n) Heisenberg chain with inverse-square exchange (ISE) are constructed using the occupation-number representation of the ``strings,'' which can be considered as the unbroken resonating-valence bonds.
Journal ArticleDOI
“Solidification” in a soluble model of bosons on a one-dimensional lattice: The “Boson-Hubbard chain”
TL;DR: In this paper, the 1-D Bose gas was put on a lattice, becoming aboson-Hubbard model, and it remains soluble by the Bethe ansatz.
Book
Localization, wave-function topology, and the integer quantized Hall effect
TL;DR: In this article, the motion of the zeros of the wave function under smooth changes of the boundary conditions is used to characterize the behavior of the one-electron states and distinguish between localized and extended states.
Journal ArticleDOI
Disorder-driven collapse of the mobility gap and transition to an insulator in the fractional quantum Hall effect.
TL;DR: The topologically invariant Chern number is calculated, which is the only quantity known at present to distinguish unambiguously between insulating and current carrying states in an interacting system and is found to agree with experimental value semiquantitatively.
Journal ArticleDOI
Probing the geometry of the Laughlin state
Sonika Johri,Zlatko Papic,Peter Schmitteckert,Peter Schmitteckert,Ravindra N. Bhatt,Frederick D. Haldane +5 more
TL;DR: In this paper, the authors perform extensive numerical studies of the geometric degree of freedom for the simplest example of fractional quantumHall states, i.e., filling v = 1/3 Laughlin state, by perturbing the system by a smooth, spatially dependent metric deformation and measure the response of the Hall fluid, finding it to be proportional to the Gaussian curvature of the metric.
