Dynamics of global and local vortices with orientational moduli
Minoru Eto, Adam Peterson, Fidel I. Schaposnik Massolo +1
The dynamics of both global and local vortices with non-Abelian orientational moduli is investigated in detail. Head-on collisions of these vortices are numerically simulated for p…
Fractional black -branes on orbifold
Muneto Nitta, Kunihito Uzawa
The recent discovery of an explicit solution of a black hole on the resolved orbifold makes it possible to investigate the existence of -branes on…
Second order chiral kinetic theory under gravity and antiparallel charge-energy flow
Tomoya Hayata, Yoshimasa Hidaka, Kazuya Mameda
We derive the chiral kinetic theory under the presence of a gravitational Riemann curvature. It is well-known that in the chiral kinetic theory there inevitably appears a redundant…
Confinement and moduli locking of Alice strings and monopoles
Muneto Nitta
We argue that strings (vortices) and monopoles are confined, when fields receiving nontrivial Aharonov-Bohm (AB) phases around a string develop vacuum expectation values (VEVs). We…
Orbifold black holes
Muneto Nitta, Kunihito Uzawa
We construct a regular black hole solution on the orbifold in the ()-dimensional Einstein-Maxwell theory. The event horizon is $S^{2n-1}/{\m…
Higher Derivative Supersymmetric Nonlinear Sigma Models on Hermitian Symmetric Spaces, and BPS States Therein
Muneto Nitta, Shin Sasaki
We formulate four-dimensional supersymmetric nonlinear sigma models on Hermitian symmetric spaces with higher derivative terms, free from the auxiliary field prob…
Exact WKB analysis of the vacuum pair production by time-dependent electric fields
Hidetoshi Taya, Toshiaki Fujimori, Tatsuhiro Misumi +2
We study the vacuum pair production by a time-dependent strong electric field based on the exact WKB analysis. We identify the generic structure of a Stokes graph for systems with…
Global 3-group symmetry and 't Hooft anomalies in axion electrodynamics
Yoshimasa Hidaka, Muneto Nitta, Ryo Yokokura
We investigate a higher-group structure of massless axion electrodynamics in dimensions. By using the background gauging method, we show that the higher-form symmetries nec…
The Volume of the Quiver Vortex Moduli Space
Kazutoshi Ohta, Norisuke Sakai
We study the moduli space volume of BPS vortices in quiver gauge theories on compact Riemann surfaces. The existence of BPS vortices imposes constraints on the quiver gauge theorie…
Topological mass generation in gapless systems
Naoki Yamamoto, Ryo Yokokura
Mass generation of gauge fields can be universally described by topological couplings in gapped systems, such as the Abelian Higgs model in dimensions and the Maxwell-Chern…
Topological structure of Nambu monopole in Two Higgs doublet models -- Fiber bundle, Dirac's quantization and dyon --
Minoru Eto, Yu Hamada, Muneto Nitta
We find a topologically non-trivial structure of the Nambu monopole in two Higgs doublet model (2HDM), which is a magnetic monopole attached by two topologically stable strings…
1/2-BPS vortex strings in supersymmetric gauge theories
Sven Bjarke Gudnason, Minoru Eto, Muneto Nitta
Strings in supersymmetric gauge theories with hypermultiplets are studied in the generic setting of an arbitrary Fayet-Iliopoulos triplet of para…
On exact-WKB analysis, resurgent structure, and quantization conditions
Naohisa Sueishi, Syo Kamata, Tatsuhiro Misumi +1
There are two well-known approaches to studying nonperturbative aspects of quantum mechanical systems: Saddle point analysis of the partition functions in Euclidean path integral f…
Counting Nambu-Goldstone modes of higher-form global symmetries
Yoshimasa Hidaka, Yuji Hirono, Ryo Yokokura
We discuss the counting of Nambu-Goldstone (NG) modes associated with the spontaneous breaking of higher-form global symmetries. Effective field theories of NG modes are developed…
Finite-Density Massless Two-Color QCD at Isospin Roberge-Weiss Point and 't Hooft Anomaly
Takuya Furusawa, Yuya Tanizaki, Etsuko Itou
We study the phase diagram of two-flavor massless two-color QCD (QCD) under the presence of quark chemical potentials and imaginary isospin chemical potentials. At the special…
The Casimir effect for nonlinear sigma models and the Mermin-Wagner-Hohenberg-Coleman theorem
Antonino Flachi, Vincenzo Vitagliano
The quantum vacuum (Casimir) energy arising from noninteracting massless quanta is known to induce a long-range force, while decays exponentially for massive fields and separations…
Deconfinement and CP-breaking at in Yang-Mills theories and a novel phase for SU(2)
Shi Chen, Kenji Fukushima, Hiromichi Nishimura +1
We discuss the deconfinement and the CP-breaking phase transitions at in Yang-Mills theories. The 't Hooft anomaly matching prohibits the confined phase with CP symmetry and…
Higher-form symmetries and 3-group in axion electrodynamics
Yoshimasa Hidaka, Muneto Nitta, Ryo Yokokura
We study higher-form symmetries in a low-energy effective theory of a massless axion coupled with a photon in dimensions. It is shown that the higher-form symmetries of thi…
Lattice model with twisted boundary condition: bions, adiabatic continuity and pseudo-entropy
Toshiaki Fujimori, Etsuko Itou, Tatsuhiro Misumi +2
We investigate the lattice sigma model on (large) (small) with the symmetric twisted boundary condition, where…
Implications of the weak gravity conjecture in anomalous quiver gauge theories
Yoshihiko Abe, Tetsutaro Higaki, Rei Takahashi
We argue a smallness of gauge couplings in abelian quiver gauge theories, taking the anomaly cancellation condition into account. In theories of our interest there exist chiral fer…
Exhausting all exact solutions of BPS domain wall networks in arbitrary dimensions
Minoru Eto, Masaki Kawaguchi, Muneto Nitta +1
We obtain full moduli parameters for generic non-planar BPS networks of domain walls in an extended Abelian-Higgs model with complex scalar fields, and exhaust all exact soluti…
Linking number of vortices as baryon number
Sven Bjarke Gudnason, Muneto Nitta
We show that the topological degree of a Skyrmion field is the same as the Hopf charge of the field under the Hopf map and thus equals the linking number of the preimages of two po…
Exact solutions of domain wall junctions in arbitrary dimensions
Minoru Eto, Masaki Kawaguchi, Muneto Nitta +1
Exact analytic solutions of static, stable, non-planar BPS domain wall junctions are obtained in extended Abelian-Higgs models in -dimensional spacetime. For specific choice…
