Emergent higher-form symmetry in Higgs phases with superfluidity
Yoshimasa Hidaka, Dan Kondo
We address emergent higher-form symmetry in Higgs phases with superfluidity. The emergent symmetry appears if a matter field is invariant under a transformation of a common subgrou…
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…
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…
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…

Kenji Fukushima, Yoshimasa Hidaka, Ho-Ung Yee
Superfluid vortices are quantum excitations carrying quantized amount of orbital angular momentum in a phase where global symmetry is spontaneously broken. We address a question of…

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…
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…

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…
Emergent discrete 3-form symmetry and domain walls
Yoshimasa Hidaka, Muneto Nitta, Ryo Yokokura
We show that axion models with the domain wall number in dimensions, i.e., periodic scalar field theories admitting axion domain walls, exhibit an emergent ${\mathb…
Spontaneous symmetry breaking and Nambu-Goldstone modes in open classical and quantum systems
Yoshimasa Hidaka, Yuki Minami
We discuss spontaneous symmetry breaking of open classical and quantum systems. When a continuous symmetry is spontaneously broken in an open system, a gapless excitation mode appe…
Topological order in a color-flavor locked phase of -dimensional gauge-Higgs system
Yoshimasa Hidaka, Yuji Hirono, Muneto Nitta +2
We study a -dimensional gauge theory with -flavor fundamental scalar fields, whose color-flavor locked (CFL) phase has topologically stable non-Abelian vortices. T…
Anomaly-induced transport phenomena from the imaginary-time formalism
Masaru Hongo, Yoshimasa Hidaka
A derivation of the anomaly-induced transport phenomena---the chiral magnetic/vortical effect---is revisited based on the imaginary-time formalism of quantum field theory. Consider…

Tomoya Hayata, Yoshimasa Hidaka
We study the Nambu-Goldstone (NG) modes associated with spontaneous breaking of the continuous time-translation symmetry. To discuss a quantum time-crystal with the spontaneously-b…
Non-equilibrium Chiral Magnetic/Vortical Effects in Viscous Fluids
Yoshimasa Hidaka, Di-Lun Yang
We utilize the chiral kinetic theory in a relaxation-time approximation to investigate the nonlinear anomalous responses of chiral fluids with viscous effects. Unlike the cases in…
Nonlinear Responses of Chiral Fluids from Kinetic Theory
Yoshimasa Hidaka, Shi Pu, Di-Lun Yang
The second-order nonlinear responses of inviscid chiral fluids near local equilibrium are investigated by applying the chiral kinetic theory (CKT) incorporating side-jump effects.…
Relativistic Chiral Kinetic Theory from Quantum Field Theories
Yoshimasa Hidaka, Shi Pu, Di-Lun Yang
The chiral kinetic theory of Weyl fermions with collisions in the presence of weak electric and magnetic fields is derived from quantum field theories. It is found that the side-ju…
Lefschetz-thimble analysis of the sign problem in one-site fermion model
Yuya Tanizaki, Yoshimasa Hidaka, Tomoya Hayata
The Lefschetz-thimble approach to path integrals is applied to a one-site model of electrons, i.e., the one-site Hubbard model. Since the one-site Hubbard model shows a non-analyti…

Yoshimasa Hidaka, Toshifumi Noumi, Gary Shiu
We discuss the effective field theory for spacetime symmetry breaking from the local symmetry point of view. By gauging spacetime symmetries, the identification of Nambu-Goldstone…

Tomoya Hayata, Yoshimasa Hidaka
We discuss the dispersion relations of Nambu-Goldstone (NG) modes associated with spontaneous breaking of internal symmetries at finite temperature and/or density. We show that the…
Broken spacetime symmetries and elastic variables
Tomoya Hayata, Yoshimasa Hidaka
We discuss spontaneous breaking of continuum symmetries, whose generators do explicitly depend on the spacetime coordinates. We clarify the relation between broken symmetries and e…

The counting rule for Nambu-Goldstone modes is discussed using Mori's projection operator method in nonrelativistic systems at zero and finite temperatures. We show that the number…
