  • Novel Lattice Formulation of 2D Chiral Gauge Theory via Bosonization Reviewed

    Okuto Morikawa, Soma Onoda, Hiroshi Suzuki

    PoS   LATTICE2024   363   2025.1

     More details

    Language:English   Publishing type:Research paper (international conference proceedings)  

    Recently, lattice formulations of 2D Abelian chiral gauge theory have been
    constructed based on Abelian bosonization. It is remarkable about these 2D
    lattice formulations that they reproduce the same gauge anomaly structure as
    the continuum theory, even at a finite lattice spacing. In this talk, we
    propose yet another lattice formulation based on the ``excision method''
    introduced recently in Ref.~\cite{Abe:2023uan}. This approach respects the
    admissibility condition, which is a constraint on the smoothness of lattice
    field configurations; it usually prohibits magnetically charged objects, that
    is, vector-charged objects in fermion theories. We show that such objects can
    be defined in the excision method as a lattice defect called a ``hole,'' and
    discuss the selection rules for charged objects.

    We present the lattice simulation of the renormalization group flow in the
    $3$-dimensional $O(N)$ linear sigma model. This model possesses a nontrivial
    infrared fixed point, called Wilson--Fisher fixed point. Arguing that the
    parameter space of running coupling constants can be spanned by expectation
    values of operators evolved by the gradient flow, we exemplify a scaling
    behavior analysis based on the gradient flow in the large $N$ approximation at
    criticality. Then, we work out the numerical simulation of the theory with
    finite $N$. Depicting the renormalization group flow along the gradient flow,
    we confirm the existence of the Wilson--Fisher fixed point non-perturbatively.

  • Action of the Axial U(1) Non-Invertible Symmetry on the’t Hooft Line Operator: A Lattice Gauge Theory Study Reviewed

    We study how the symmetry operator of the axial U(1) non-invertible symmetry acts on the’t Hooft line operator in the U(1) gauge theory by employing the modified Villain-type lattice formulation. We model the axial anomaly by a compact scalar boson, the “QED axion”. For the gauge invariance, the simple’t Hooft line operator, which is defined by a line integral of the dual U(1) gauge potential, must be “dressed” by the scalar and U(1) gauge fields. A careful consideration on the basis of the anomalous Ward–Takahashi identity containing the’t Hooft operator with the dressing factor and a precise definition of the symmetry operator on the lattice shows that the symmetry operator leaves no effect when it sweeps out a’t Hooft loop operator. This result appears inequivalent with the phenomenon concluded in the continuum theory. In an appendix, we demonstrate that the half-space gauging of the magnetic ZN 1-form symmetry, when formulated in an appropriate lattice framework, leads to the same conclusion as above. A similar result is obtained for the axion string operator.

    2005.6

     More details

    We present a manifestly gauge-invariant description of Chern numbers associated with the Berry connection defined on a discretized Brillouin zone. It provides an efficient method of computing (spin) Hall conductances without specifying gauge-fixing conditions. We demonstrate that it correctly reproduces quantized Hall conductances even on a coarsely discretized Brillouin zone. A gauge-dependent integer-valued field, which plays a key role in the formulation, is evaluated in several gauges. An extension to the non-Abelian Berry connection is also given.
