Scaling limit of the staggered six-vertex model with invariant boundary conditions
Holger Frahm, Sascha Gehrmann, Gleb A. Kotousov
We study the scaling limit of a statistical system, which is a special case of the integrable inhomogeneous six-vertex model. It possesses invarianc…
Asymptotic Symmetries of SU(2) Yang-Mills-Higgs Theory in Hamiltonian Formulation
Lena Janshen, Domenico Giulini
We investigate the asymptotic symmetry group of a SU(2)-Yang-Mills theory coupled to a Higgs field in the Hamiltonian formulation. This extends previous work on the asymptotic stru…
Effective action and black hole solutions in asymptotically safe quantum gravity
Jan M. Pawlowski, Jan Tränkle
We derive the quantum effective action and the respective quantum equations of motion from multi-graviton correlation functions in asymptotically safe quantum gravity. The fully mo…
A Casimir operator for a Calogero algebra
Francisco Correa, Gonzalo Leal, Olaf Lechtenfeld +1
We investigate the nonlinear algebra generated by the 9 functionally independent permutation-symmetric operators in the three-particle rational quantum Calogero model. Decoup…
quantum chains with quantum group invariant boundaries
Holger Frahm, Márcio J. martins
Based on the finite-size analysis of the spectrum of the quantum group invariant deformation of the superspin chain we identify the operator content of the conformal fie…
The spin chain and its finite-size spectrum
Holger Frahm, Sascha Gehrmann, Rafael I. Nepomechie +1
Using the analytic Bethe ansatz, we initiate a study of the scaling limit of the quasi-periodic spin chain. Supported by a detailed symmetry analysis, we determine the…
