Symmetry Breaking in an Extended O(2) Model

Autor: Hostetler, Leon, Sakai, Ryo, Zhang, Jin, Bazavov, Alexei, Meurice, Yannick

Publikováno v: Phys. Rev. D 109, 054514 (2024)

Motivated by attempts to quantum simulate lattice models with continuous Abelian symmetries using discrete approximations, we study an extended-O(2) model in two dimensions that differs from the ordinary O(2) model by the addition of an explicit symm

We study the correlator of temporal Wilson lines at non-zero temperature in 2+1 flavor lattice QCD with the aim to define the heavy quark-antiquark potential at non-zero temperature. For temperatures $153~{\rm MeV} \leq T \leq 352~{\rm MeV}$ the spec

Autor: Bazavov, Alexei, DeTar, Carleton, El-Khadra, Aida X., Gámiz, Elvira, Gelzer, Zechariah, Gottlieb, Steven, Jay, William I., Jeong, Hwancheol, Kronfeld, Andreas S., Li, Ruizi, Lytle, Andrew T., Mackenzie, Paul B., Neil, Ethan T., Primer, Thomas, Simone, James N., Sugar, Robert L., Toussaint, Doug, Van de Water, Ruth S., Vaquero, Alejandro

We present lattice-QCD calculations of the hadronic form factors for the semileptonic decays $D\to\pi\ell\nu$, $D\to K\ell\nu$, and $D_s\to K\ell\nu$. Our calculation uses the highly improved staggered quark (HISQ) action for all valence and sea quar

Symmetry Breaking in an Extended-O(2) Model

Autor: Hostetler, Leon, Sakai, Ryo, Zhang, Jin, Unmuth-Yockey, Judah, Bazavov, Alexei, Meurice, Yannick

Publikováno v: PoS(LATTICE2022)014

Motivated by attempts to quantum simulate lattice models with continuous Abelian symmetries using discrete approximations, we consider an extended-O(2) model that differs from the ordinary O(2) model by an explicit symmetry breaking term. Its couplin
