Can high-energy physics be simulated by low-energy, non-relativistic, many-body systems
such as ultracold atoms? Such ultracold atomic systems lack the type of symmetries and …

The development of Relativistic Quantum Field Theory started in 1932 as a natural
extension of Quantum Mechanics to the relativistic domain [1]. The work of Feynman in the …

We show that $2 $ d adjoint QCD, an $ SU (N) $ gauge theory with one massless adjoint
Majorana fermion, has a variety of mixed't Hooft anomalies. The anomalies are derived …

A bstract We study the domain walls in hot 4-D SU (N) super Yang-Mills theory and QCD
(adj), with nf Weyl flavors. We find that the k-wall worldvolume theory is 2-D QCD with gauge …

QFTs with local topological operators feature unusual sectors called" universes," which are
separated by infinite-tension domain walls. We show that such systems have relevant …

Providing a new perspective on quantum field theory, this book gives a pedagogical
exposition of non-perturbative methods in relativistic quantum field theory and introduces the …

A bstract We study the vacuum structure of N f flavour two-dimensional QED with an arbitrary
integer charge k. We find that the axial symmetry is spontaneously broken from\({\mathbb …

A bstract We study worldsheet theory of confining strings in two-dimensional massive adjoint
QCD. Similarly to confining strings in higher dimensions this theory exhibits a non-trivial S …

We study the spectrum of (1+ 1)-dimensional large N QCD coupled to an adjoint Majorana
fermion of mass m. As m→ 0 this model makes a transition from confinement to screening …

In a numerical Monte Carlo simulation of SU (2) Yang-Mills theory with light dynamical
gluinos the low energy features of the dynamics as confinement and bound state mass …
