A New Type of Lattice Gauge Theory through Self-adjoint Extensions
A. Banerjee, D. Banerjee, G. Kanwar +3
A generalization of Wilsonian lattice gauge theory may be obtained by considering the possible self-adjoint extensions of the electric field operator in the Hamiltonian formalism.…
Improved lattice method for determining entanglement measures in SU(N) gauge theories
Tobias Rindlisbacher, Niko Jokela, Arttu Pönni +2
The determination of entanglement measures in SU(N) gauge theories is a non-trivial task. With the so-called "replica trick", a family of entanglement measures, known as "Rényi ent…
Infinite-range correlations in 1D systems with continuous symmetry
Tobias Rindlisbacher
O(N)-symmetric lattice scalar fields are considered, coupled to a chemical potential and source terms. At the example of N=2, it is shown that such systems can even in (0+1) dimens…
Safety versus triviality on the lattice
Viljami Leino, Tobias Rindlisbacher, Kari Rummukainen +2
We present the first numerical study of the ultraviolet dynamics of non-asymptotically free gauge-fermion theories at large number of matter fields. As testbed theories we consider…
A Worm Algorithm for the Lattice CP(N-1) Model
Tobias Rindlisbacher, Philippe de Forcrand
The CP(N-1) model in 2D is an interesting toy model for 4D QCD as it possesses confinement, asymptotic freedom and a non-trivial vacuum structure. Due to the lower dimensionality a…
