Tardos fingerprinting is better than we thought
B. Skoric, T. U. Vladimirova, M. Celik +1
We review the fingerprinting scheme by Tardos and show that it has a much better performance than suggested by the proofs in Tardos' original paper. In particular, the length of th…
Asymptotically exact solutions of Harper equation
A. G. Abanov, J. C. Talstra, P. B. Wiegmann
We present asymptotically exact solutions of an incommensurate Harper equation---one-dimensional Schroedinger equation of one particle on a lattice in a cosine potential. The wave…
Hierarchical Structure of Azbel-Hofstader Problem: Strings and loose ends of Bethe Ansatz
A. G. Abanov, J. C. Talstra, P. B. Wiegmann
We present numerical evidence that solutions of the Bethe Ansatz equations for a Bloch particle in an incommensurate magnetic field (Azbel-Hofstadter or AH model), consist of compl…
An Order Parameter for the Mott-Hubbard Transition in One Dimension
S. P. Strong, J. C. Talstra
We propose an order parameter for the one dimensional Mott-Hubbard transition and provide numerical evidence and general theoretical arguments for the correctness of our proposal.…
A Creation Operator for Spinons in One Dimension
S. P. Strong, J. C. Talstra
We propose a definition for a creation operator for the spinon, the fractional statistics elementary excitation of the Haldane-Shastry model, and give numerical and analytical evid…
Period doubling in the 2D Antiferromagnet. New gauge-fields and their anomalies
A. G. Abanov, J. C. Talstra
We construct an effective gauge field theory model describing a 2D quantum antiferromagnet in the flux phase ground state. Due to period doubling the number of gauge fields is four…
