Investigation of the 1+1 dimensional Thirring model using the method of matrix product states
Mari Carmen Banuls, Krzysztof Cichy, Ying-Jer Kao +3
We present preliminary results of a study on the non-thermal phase structure of the (1+1) dimensional massive Thirring model, employing the method of matrix product states. Through…
Sp(4) gauge theory on the lattice: towards SU(4)/Sp(4) composite Higgs (and beyond)
Ed Bennett, Deog Ki Hong, Jong-Wan Lee +4
The Sp(4) gauge theory with two Dirac fundamental flavours provides a candidate for the microscopic origin of composite-Higgs models based on the SU(4)/Sp(4) coset. We employ a com…
Finite Size Scaling of the Higgs-Yukawa Model near the Gaussian Fixed Point
David Y. -J. Chu, Karl Jansen, Bastian Knippschild +2
We study the scaling properties of Higgs-Yukawa models. Using the technique of Finite-Size Scaling, we are able to derive scaling functions that describe the observables of the mod…

Cynthia Y. -H. Huang, Issaku Kanamori, C. -J. David Lin +4
We present our investigation of SU(2) gauge theory with 8 flavours, and SU(3) gauge theory with 12 flavours. For the SU(2) case, at strong bare coupling, , the dist…

David Y. -J. Chu, Karl Jansen, Bastian Knippschild +3
We derive finite-size scaling formulae for four-dimensional Higgs-Yukawa models near the Gaussian fixed point. These formulae will play an essential role in future, detailed invest…

David Y. -J. Chu, Karl Jansen, Bastian Knippschild +2
We discuss the non-thermal phase structure of a chirally invariant Higgs-Yukawa model on the lattice in the presence of a higher dimensional -term. For the exploration of the…

Cynthia Y. -H. Huang, C. -J. David Lin, Kenji Ogawa +2
We present the investigation of the strong bare-coupling regime of SU(2) lattice gauge theory with 8 fermion flavors in the fundamental representation. The simulations are performe…

Prasad Hegde, George W. -S. Hou, Karl Jansen +5
We present new results of our ongoing project on the investigation of the phase structure of the Higgs-Yukawa model at small and large bare Yukawa couplings. The critical exponents…
Axial couplings of heavy hadrons from domain-wall lattice QCD
William Detmold, C. -J. David Lin, Stefan Meinel
We calculate matrix elements of the axial current for static-light mesons and baryons in lattice QCD with dynamical domain wall fermions. We use partially quenched heavy hadron chi…
