Lattice chiral non-Abelian gauge symmetry via bosonization

Soma Onoda

A central issue in lattice formulations of chiral gauge theories is how the anomaly cancellation mechanism of the continuum theory can be realized at finite lattice spacing. In the…

Eigenstate Thermalization Hypothesis with projective representation

Soma Onoda, Osamu Fukushima, Ryusuke Hamazaki +1

The Eigenstate Thermalization Hypothesis (ETH) provides a sufficient condition for thermalization of isolated quantum systems. While the standard ETH is formulated in the absence o…

Geometric phase from encircling an exceptional point of a quantum resonance in the complex-scaling method

Okuto Morikawa, Shoya Ogawa, Soma Onoda

Non-Hermitian operators are now routinely used to describe few-mode systems such as optical resonators and superconducting qubits, and exceptional points (EPs) are defective spectr…

't Hooft line in 4D lattice gauge theory and a microscopic description of dyon's statistics

Soma Onoda

In lattice gauge theory with compact gauge field variables, an introduction of the gauge field topology requires the assumption that lattice field configurations are sufficiently s…

Novel Lattice Formulation of 2D Chiral Gauge Theory via Bosonization

Okuto Morikawa, Soma Onoda, Hiroshi Suzuki

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…

Axion QED as a Lattice Gauge Theory and Non-Invertible Symmetry

Yamato Honda, Soma Onoda, Hiroshi Suzuki

We investigate the non-invertible symmetry associated with chiral symmetry in axion quantum electrodynamics (QED) using the modified Villain formulation. In axion QED, it is known…
