The performance of the TA4 surface detector array: 4.3 years of the first-half expansion

Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126

The Telescope Array (TA) experiment aims to reveal the origin of ultra-high-energy cosmic rays (UHECRs) by observing air showers using surface detectors (SDs), which spread over an…

Tripling Fluctuations and Peaked Sound Speed in Fermionic Matter

Hiroyuki Tajima, Kei Iida, Toru Kojo +1

A crossover involving three-fermion clusters is relevant to the hadron-quark crossover, which, if occurring in a neutron star, could naturally reproduce the dense-matter equation o…

Modified dilepton production rate from charged pion-pair annihilation in the inhomogeneous chiral condensed phase

Kentaro Hayashi, Yasuhiko Tsue

We investigate the dilepton production rates from annihilation processes of charged pion pairs with modified pion dispersion relations in the inhomogeneous chiral condensed phase.…

Non-relativistic trace anomaly and equation of state in dense fermionic matter

Hiroyuki Tajima, Kei Iida, Haozhao Liang

We theoretically investigate a non-relativistic trace anomaly and its impact on the low-temperature equation of state in spatially one-dimensional three-component fermionic systems…

Intersections of ultracold atomic polarons and nuclear clusters: How is a chart of nuclides modified in dilute neutron matter?

Hiroyuki Tajima, Hajime Moriya, Wataru Horiuchi +2

Neutron star observations, as well as experiments on neutron-rich nuclei, used to motivate one to look at degenerate nuclear matter from its extreme, namely, pure neutron matter. A…

Polaronic Proton and Diproton Clustering in Neutron-Rich Matter

Hiroyuki Tajima, Hajime Moriya, Wataru Horiuchi +2

We show that strong spin-triplet neutron-proton interaction causes polaronic protons to occur in neutron matter at subnuclear densities and nonzero temperature. As the neutron dens…
