Quantum-Geometric Meissner Effect in Magnetized Color Superconductors
Kazuya Mameda, Noriyuki Sogabe
We find a quantum-geometric Meissner response in magnetized two-flavor color-superconducting (2SC) quark matter. Landau quantization quenches the transverse quasiparticle dispersio…
Anomaly-Induced Phenomena with Massive Fermions: Higher-Landau-Level Dominance from Spatially Modulated Electric Fields
Koichi Hattori, Kazuya Mameda, Takeru Uchiyama +1
We investigate the axial Ward identity for massive fermions under a constant magnetic field at arbitrary strength, maintaining an arbitrary spacetime configuration of a perturbativ…
Baryonic vortices in rotating nuclear matter
Kazuya Mameda, Muneto Nitta, Zebin Qiu
We investigate baryonic vortices as topological excitations in rotating nuclear matter within the framework of chiral perturbation theory. We identify two distinct configurations:…
Susceptibilities of rotating quark matter in Fourier-Bessel basis
Mamiya Kawaguchi, Kazuya Mameda
We analyze various two-point correlation functions of fermionic bilinears in a rotating finite-size cylinder at finite temperatures, with a focus on susceptibility functions. Due t…
FRG analysis for a relativistic BEC in arbitrary spatial dimensions
Fumio Terazaki, Kazuya Mameda
A relativistic Bose-Einstein condensate (BEC) is studied within the complex scalar field theory using the functional renormalization group (FRG) under the local potential approxima…
Preponderant Orbital Polarization in Relativistic Magnetovortical Matter
Kenji Fukushima, Koichi Hattori, Kazuya Mameda
We establish thermodynamic stability and gauge invariance in the magnetovortical matter of Dirac fermions under the coexistent rotation and strong magnetic field. The corresponding…
Relativistic BEC extracted from a complex FRG flow equation
Fumio Terazaki, Kazuya Mameda, Katsuhiko Suzuki
Based on the functional renormalization group (FRG) under the local potential approximation, we analyze the Bose-Einstein condensation (BEC) in the relativistic complex scalar theo…
Deconfinement transition in the revolving bag model
Kazuya Mameda, Keiya Takizawa
Based on the bag model, we revisit the deconfinement phase transition under rotation. On top of the usual rotational energy for noninteracting particles, we perturbatively analyze…
Covariant Spin Kinetic Theory I: Collisionless Limit
Yu-Chen Liu, Kazuya Mameda, Xu-Guang Huang
We develop a covariant kinetic theory for massive fermions in curved spacetime and external electromagnetic field based on quantum field theory. We derive four coupled semi-classic…
Surface Magnetic Catalysis
Hao-Lei Chen, Kenji Fukushima, Xu-Guang Huang +1
We study fermions in a magnetic field in a finite size cylinder. With the boundary condition for the fermion flux, we show that the energy spectra and the wave-functions are modifi…
Boundary effects and gapped dispersion in rotating fermionic matter
Shu Ebihara, Kenji Fukushima, Kazuya Mameda
We discuss the importance of boundary effects on fermionic matter in a rotating frame. By explicit calculations at zero temperature we show that the scalar condensate of fermion an…
Analogy between rotation and density for Dirac fermions in a magnetic field
Hao-Lei Chen, Kenji Fukushima, Xu-Guang Huang +1
We analyse the energy spectra of Dirac fermions in the presence of rotation and magnetic field. We find that the Landau degeneracy is resolved by rotation. A drastic change in the…
QCD -vacua from the chiral limit to the quenched limit
Kazuya Mameda
We investigate the dependence of the QCD vacuum structure on the -angle and quark mass, using the Di-Vecchia--Veneziano model. Although the Di-Vecchia--Veneziano model is a chir…
Wess-Zumino-Witten action and photons from the Chiral Magnetic Effect
Kenji Fukushima, Kazuya Mameda
We revisit the Chiral Magnetic Effect (CME) using the chiral Lagrangian. We demonstrate that the electric-current formula of the CME is derived immediately from the contact part of…
