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…
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…
'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…
