The measurement of low-energy cosmic anti-deuterons may reveal the existence of exotic processes such as dark-matter annihilation, since the production rate of these ions through ordinary secondary processes is very low. However, the lack of experimental data at low energies, where both the anti-deuteron production and inelastic cross sections are very poorly known, prevents precise...
Masses and radii of neutron stars and the recent data from LIGO suggest that
the sound velocity is greater than or of the order of 1/3 at densities a few times that of nuclear matter. We show that this arises naturally if nuclear matter is Quarkyonic. Quarkyonic matter has a shell in the Fermi surface of nuclear matter
and Fermi sea of quarks. We discuss how this shell might arise dynamically
Quark-hadron continuity has been well understood for three-flavor symmetric nuclear and quark matter, which is however a theoretically over-idealized environment. In this talk we clarify how quark-hadron continuity can be applied to neutron matter in the realistic neutron star environment. Our key observation is that neutron matter can be smoothly connected to the two-flavor...
Merging binaries of neutron stars are not only strong sources of gravitational waves, but also have the potential of revealing states of matter at densities and temperatures not accessible in laboratories. A crucial and longstanding question in this context is whether quarks are deconfined as a result of the dramatic increase in density and temperature following the merger. We present the...
Sharing and transfer of chirality between gauge fields and fermion plays a crucial role for understanding the dynamics of anomalous transport phenomena such as the Chiral Megnetic Effect. We present a first principles study of the chirality transfer between gauge fields and fermions based on classical-statistical real-time lattice simulations. We demonstrate that a chirality imbalance in the...
