Connecting lattice and relativistic models via conformal field theory
H. E. Boos, V. E. Korepin, F. A. Smirnov
We consider the quantum group invariant XXZ-model. In infrared limit it describes Conformal Field Theory with modified energy-momentum tensor. The correlation functions are related…
Universality of Entropy Scaling in 1D Gap-less Models
Vladimir Korepin
We consider critical models in one dimension. We study the ground state in thermodynamic limit [infinite lattice]. Following Bennett, Bernstein, Popescu, and Schumacher, we use the…
Correlation Functions in Spin Chains and Information Theory
B. -Q. Jin, V. E. Korepin
Antiferromagnetic spin chains play an important role in condensed matter physics and statistical mechanics. Recently XXX spin chain was discussed in relation to the information the…
New formulae for solutions of quantum Knizhnik-Zamolodchikov equations on level -4 and correlation functions
Hermann Boos, Vladimir Korepin, Feodor Smirnov
This paper is continuation of our previous papers hep-th/0209246 and hep-th/0304077 . We discuss in more detail a new form of solution to the quantum Knizhnik-Zamolodchikov equatio…
Quantum Spin Chain, Toeplitz Determinants and Fisher-Hartwig Conjecture
B. -Q. Jin, V. E. Korepin
We consider one-dimensional quantum spin chain, which is called XX model, XX0 model or isotropic XY model in a transverse magnetic field. We study the model on the infinite lattice…
New formulae for solutions of quantum Knizhnik-Zamolodchikov equations on level -4
Hermann Boos, Vladimir Korepin, Feodor Smirnov
We present a new form of solution to the quantum Knizhnik-Zamolodchikov equation on level -4 in a special case corresponding to the Heisenberg XXX spin chain. Our form is equivalen…
