Moment of Inertia of an Interacting Bose Gas

Aleksandar Gecic, Victor E. Ambrus, Kenji Fukushima

The response of many-body quantum systems to rotation can be characterized by the moment of inertia. For a classical gas, the moment of inertia can be expressed as the integral of…

Local Spin Polarization in Anisotropic Gubser Flow: Suppression Mechanism and Formulation Dependence

Kenji Fukushima, Shi Pu, Dong-Lin Wang

We analytically study the longitudinal spin polarization in relativistic heavy-ion collisions using a perturbed Gubser flow solution. In the large-system-size limit, we derive anal…

Polarized Nucleon as a Topological Dipole

Kenji Fukushima, Tomoya Uji

We show that a polarized nucleon generically carries a dipole distribution of topological charge density. This topological dipole follows robustly from the definition of the topolo…

Magnetic-type Love number differentiating quark stars from neutron stars

Kenji Fukushima, Josuke Minamiguchi, Tomoya Uji

The quark star (QS) is a hypothetical and yet undiscovered stellar object, and its existence would mark a paradigm shift in research on nuclear and quark matter. Although compactne…

Pseudogauge ambiguity in the distributions of energy density, pressure, and shear force inside the nucleon

Kenji Fukushima, Tomoya Uji

We study the spatial distributions of pressure, energy density, and shear forces inside the nucleon within the two-flavor Skyrme model including vector mesons. This framework has t…

A New State of Matter between the Hadronic Phase and the Quark-Gluon Plasma?

Yuki Fujimoto, Kenji Fukushima, Yoshimasa Hidaka +1

Lattice-QCD simulations and theoretical arguments hint at the existence of an intermediate phase of strongly interacting matter between a confined hadron gas and a deconfined Quark…
