Benchmark results in the 2D lattice Thirring model with a chemical potential
Venkitesh Ayyar, Shailesh Chandrasekharan, Jarno Rantaharju
We study the two dimensional lattice Thirring model in the presence of a fermion chemical po- tential. Our model is asymptotically free, contains massive fermions that mimic a bary…
Confinement study of an SU(4) gauge theory with fermions in multiple representations
Venkitesh Ayyar, Daniel Hackett, William Jay +1
We discuss the phase diagnostics used in our finite-temperature study of an SU(4) gauge theory with dynamical fermions in both the fundamental and two-index antisymmetric represent…
Spectroscopy of SU(4) composite Higgs theory with two distinct fermion representations
Venkitesh Ayyar, Thomas DeGrand, Maarten Golterman +5
We have simulated the SU(4) lattice gauge theory coupled to dynamical fermions in the fundamental and two-index antisymmetric (sextet) representations simultaneously. Such theories…
Chiral Transition of SU(4) Gauge Theory with Fermions in Multiple Representations
Venkitesh Ayyar, Thomas DeGrand, Daniel C. Hackett +4
We report preliminary results on the finite temperature behavior of SU(4) gauge theory with dynamical quarks in both the fundamental and two-index antisymmetric representations. Th…
Generating a non-perturbative mass gap using Feynman diagrams in an asymptotically free theory
Venkitesh Ayyar, Shailesh Chandrasekharan
Using the example of a two dimensional four-fermion lattice field theory we demonstrate that Feynman diagrams can generate a mass gap when massless fermions interact via a marginal…
