Bismut-Torsion-Parallel Hermitian Manifolds With Constant Chern Holomorphic Sectional Curvature
Haohao Wang
A well-known conjecture in complex geometry states that a compact Hermitian manifold with constant Chern holomorphic sectional curvature must be Kähler when the constant is nonzero…
Exact WKB analysis of inverted triple-well: resonance, PT-symmetry breaking, and resurgence
Syo Kamata, Tatsuhiro Misumi, Cihan PazarbaÅı +1
We study non-Hermitian quantum mechanics of an inverted triple-well potential within the exact WKB framework. For a single classical potential, different Siegert boundary condition…
One-pion exchange potential in a strong magnetic field
Daiki Miura, Masaru Hongo, Hidetoshi Taya +1
We derive the one-pion exchange potential (OPEP) in the presence of a homogeneous magnetic field using chiral perturbation theory with nonrelativistic nucleons. Our approach is app…
Schwinger effect in QCD and nuclear physics
Hidetoshi Taya
We provide a pedagogical review of the Schwinger effect, i.e., the non-perturbative production of particle and anti-particle pairs from the vacuum by strong fields, as well as rela…
Optimal collision-energy range for realizing macroscopic high-baryon-density matter
Hidetoshi Taya, Asanosuke Jinno, Masakiyo Kitazawa +1
We investigate the volume and lifetime of the high baryon-density matter created in heavy-ion collisions and estimate the optimal collision-energy range to realize the high baryon-…
Spacetime profile of electromagnetic fields in intermediate-energy heavy-ion collisions
Hidetoshi Taya
I numerically estimate the spacetime profile of the electromagnetic fields produced in intermediate-energy heavy-ion collisions at $\sqsNN=2.4\,\mathchar`-\,7.7\;{\rm GeV}$ for a w…
