Anomalous tunneling as a low-energy theorem for Nambu-Goldstone modes
Keisuke Fujii, Daichi Kagamihara, Masaru Hongo
Anomalous tunneling refers to the phenomenon in which the transmission coefficient through a potential barrier approaches unity as the energy of an incident particle or quasipartic…
Interaction between nuclear clusters and superfluid phonons in the neutron-star inner crust
Masayuki Matsuo, Arata Nishiwaki, Toshiyuki Okihashi +1
The interaction between lattice vibrations of nuclear clusters and superfluid phonons associated with neutron superfluidity plays an important role in the dynamics of the neutron-s…
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…
Enhancement of photon emission rate near QCD critical point
Yukinao Akamatsu, Masayuki Asakawa, Masaru Hongo +2
We compute photon emission rate enhancement near the QCD critical point using an effective theory of dynamic critical phenomena and derive a universal photon spectrum. The emission…
Complex-valued in-medium potential between heavy impurities in ultracold atoms
Yukinao Akamatsu, Shimpei Endo, Keisuke Fujii +1
We formulate the induced potential in a finite temperature cold atomic medium between two heavy impurities, or polarons, which is shown to be \textit{complex-valued} in general. Th…
Effective field theory for weakly bound two-neutron halo nuclei: corrections from neutron-neutron effective range
Davi B. Costa, Masaru Hongo, Dam Thanh Son
Using an effective field-theoretical approach, we investigate the properties of weakly bound two-neutron halo nuclei (also known as Borromean nuclei) that do not support a low-ener…
