Subtleties of Non-Abelian Gauge Theories in Cold-Atomic Lattices
Peter Orland
I point out two of the subtleties referred to in the title. The first is that gauge-invariant magnetic systems may realized under general circumstances, as suggested by a simple th…
Exact Correlators in the 't Hooft Limit of the Principal Chiral Model
Peter Orland
The properties of (N X N)-matrix-valued-field theories, in the limit N goes to infinity, are harder to obtain than those for isovector-valued field theories. This is because we kno…
Applying Integrability to Gauge Theories
Peter Orland
Lattice Yang-Mills theories in any dimension may be regarded as coupled 1+1-dimensional integrable field theories. These integrable systems decouple at large center-of-mass energie…
Lattice QCD-2+1
Peter Orland
We consider a 2+1-dimensional SU(N) lattice gauge theory in an axial gauge with the link field U in the 1-direction set to one. The term in the Hamiltonian containing the square of…
Griffiths Inequalities for some O(n) Classical Spin Models with
Peter Orland
The first and second Griffiths inequalities are proved for some classical O()-invariant spin models (including Euclidean quantum field theories) for any . The proof assumes a…
