Resurgence and semiclassical expansion in two-dimensional large- sigma models
Hiromichi Nishimura, Toshiaki Fujimori, Tatsuhiro Misumi +2
The resurgence structure of the 2d sigma model at large is studied with a focus on an IR momentum cutoff scale that regularizes IR singularities in the semiclassical…
Negative string tension of higher-charge Schwinger model via digital quantum simulation
Masazumi Honda, Etsuko Itou, Yuta Kikuchi +1
We study some properties of generalized global symmetry for the charge- Schwinger model in the Hamiltonian formalism, which is the -dimensional quantum electrodynamics wi…
Exact-WKB analysis for SUSY and quantum deformed potentials: Quantum mechanics with Grassmann fields and Wess-Zumino terms
Syo Kamata, Tatsuhiro Misumi, Naohisa Sueishi +1
Quantum deformed potentials arise naturally in quantum mechanical systems of one bosonic coordinate coupled to Grassmann valued fermionic coordinates, or to a topological Wes…
Supersymmetric Gauge Theory on the Graph
Kazutoshi Ohta, So Matsuura
We consider two-dimensional N=(2,2) supersymmetric gauge theory on discretized Riemann surfaces. We find that the discretized theory can be efficiently described by using graph the…
One-loop effective action of the model at large
Antonino Flachi, Guglielmo Fucci
In this note we consider a non-linear, large- sigma model on a finite size interval with periodic boundary conditions, at finite temperature and chemical po…
Deriving dilaton potential in improved holographic QCD from meson spectrum
Koji Hashimoto, Keisuke Ohashi, Takayuki Sumimoto
We derive an explicit form of the dilaton potential in improved holographic QCD (IHQCD) from the experimental data of the meson spectrum. For this purpose we make use of the em…
Global 4-group symmetry and 't Hooft anomalies in topological axion electrodynamics
Yoshimasa Hidaka, Muneto Nitta, Ryo Yokokura
We study higher-form global symmetries and a higher-group structure of a low-energy limit of -dimensional axion electrodynamics in a gapped phase described by a topological…
Fractional Skyrmion molecules in a model
Yutaka Akagi, Yuki Amari, Sven Bjarke Gudnason +2
We study fractional Skyrmions in a baby Skyrme model with a generalization of the easy-plane potential. By numerical methods, we find stable, metastable, and unstab…
4D effective action from non-Abelian DBI action with magnetic flux background
Yoshihiko Abe, Tetsutaro Higaki, Tatsuo Kobayashi +2
We study a systematic derivation of four dimensional supersymmetric effective theory from ten dimensional non-Abelian Dirac-Born-Infeld action compactified on a six…
Topological axion electrodynamics and 4-group symmetry
Yoshimasa Hidaka, Muneto Nitta, Ryo Yokokura
We study higher-form symmetries and a higher group in the low energy limit of a -dimensional axion electrodynamics with a massive axion and a massive photon. A topological f…
Bosons on a rotating ring with free boundary conditions
Olindo Corradini, Antonino Flachi, Giacomo Marmorini +2
We consider a system of interacting non-relativistic bosons confined to a one-dimensional ring in the presence of a synthetic gauge field induced by a rotating barrier. Interaction…
The moduli space of non-Abelian vortices in Yang-Mills-Chern-Simons-Higgs theory
Sven Bjarke Gudnason, Minoru Eto
We determine the dimension of the moduli space of non-Abelian vortices in Yang-Mills-Chern-Simons-Higgs theory in 2+1 dimensions for gauge groups $G=({\rm U}(1)\times G')/\mathbb{Z…
Positive magnetoresistance induced by hydrodynamic fluctuations in chiral media
Noriyuki Sogabe, Naoki Yamamoto, Yi Yin
We analyze the combined effects of hydrodynamic fluctuations and chiral magnetic effect (CME) for a chiral medium in the presence of a background magnetic field. Based on the recen…
SM gauge fields localized on non-Abelian vortices in 6 dimensions
Masato Arai, Filip Blaschke, Minoru Eto +2
A brane-world GUT model with global non-Abelian vortices is constructed in six-dimensional spacetime. We find a solution with a vortex associated to separated from…
Quantum phase transition and Resurgence: Lessons from 3d SQED
Toshiaki Fujimori, Masazumi Honda, Syo Kamata +3
We study a resurgence structure of a quantum field theory with a phase transition to uncover relations between resurgence and phase transitions. In particular, we focus on three-di…
Helical magnetic effect and the chiral anomaly
Naoki Yamamoto, Di-Lun Yang
In the presence of the fluid helicity , the magnetic field induces an electric current of the form $\boldsymbol{j} = C_{\rm HME} (\boldsymbol{v}…
New effect in wave-packet scattering of quantum fields
Kenzo Ishikawa, Kenji Nishiwaki, Kin-ya Oda
We report calculations of a wave-packet amplitude of the two-body scattering , which leads to the measured probability in realistic experiments. We elucidate the dec…
