Correlation lengths of the repulsive one-dimensional Bose gas
Ovidiu I. Patu, Andreas Klumper
We investigate the large-distance asymptotic behavior of the static density-density and field-field correlation functions in the one-dimensional Bose gas at finite temperature. The…
Universal integrability objects
H. Boos, F. Göhmann, A. Klümper +2
We discuss the main points of the quantum group approach in the theory of quantum integrable systems and illustrate them for the case of the quantum group $U_q(\mathcal L(\mathfrak…
Finite temperature correlation functions from discrete functional equations
Britta Aufgebauer, Andreas Klümper
We present a new approach to the static finite temperature correlation functions of the Heisenberg chain based on functional equations. An inhomogeneous generalization of the n-sit…
Universal R-matrix and functional relations
H. Boos, F. Göhmann, A. Klümper +2
We collect and systematize general definitions and facts on the application of quantum groups to the construction of functional relations in the theory of integrable systems. As an…
On the absorption of microwaves by the one-dimensional spin-1/2 Heisenberg-Ising magnet
M. Brockmann, F. Göhmann, M. Karbach +2
We analyze the absorption of microwaves by the Heisenberg-Ising chain combining exact calculations, based on the integrability of the model, with numerical calculations. Within lin…
Entanglement spectra of q-deformed higher spin VBS states
Raul A. Santos, Francis N. C. Paraan, Vladimir E. Korepin +1
We calculate the reduced density matrix of a block of integer spin-S's in a q-deformed valence-bond-solid (VBS) state. This matrix is diagonalized exactly for an infinitely long bl…
Universal probes for antiferromagnetic correlations and entropy in cold fermions on optical lattices
E. V. Gorelik, D. Rost, T. Paiva +3
We determine antiferromagnetic (AF) signatures in the half-filled Hubbard model at strong coupling on a cubic lattice and in lower dimensions. Upon cooling, the transition from the…
