Generalizations of some integrals over the unitary group
B. Schlittgen, T. Wettig
Using the character expansion method, we generalize several well-known integrals over the unitary group to the case where general complex matrices appear in the integrand. These in…
The Color-Flavor Transformation and Lattice QCD
B. Schlittgen, T. Wettig
We present the color-flavor transformation for gauge group SU(N_c) and discuss its application to lattice QCD.
Quantum Link Models with Many Rishon Flavors and with Many Colors
O. Baer, R. Brower, B. Schlittgen +1
Quantum link models are a novel formulation of gauge theories in terms of discrete degrees of freedom. These degrees of freedom are described by quantum operators acting in a finit…
Low-Energy Effective Theories of Quantum Link and Quantum Spin Models
B. Schlittgen, U. -J. Wiese
Quantum spin and quantum link models provide an unconventional regularization of field theory in which classical fields arise via dimensional reduction of discrete variables. This…
Flop Transitions in Cuprate and Color Superconductors: From SO(5) to SO(10) Unification?
S. Chandrasekharan, V. Chudnovsky, B. Schlittgen +1
The phase diagrams of cuprate superconductors and of QCD at non-zero baryon chemical potential are qualitatively similar. The Neel phase of the cuprates corresponds to the chirally…
Quantum Spin Formulation of the Principal Chiral Model
B. Schlittgen, U. -J. Wiese
We formulate the two-dimensional principal chiral model as a quantum spin model, replacing the classical fields by quantum operators acting in a Hilbert space, and introducing an a…
