62. From effective field theories of higher-form symmetries to neutron stars and superfluids

Saso Grozdanov (University of Edinburgh, University of Ljubljana)

Talk

In this talk, I will review recent progress in formulating effective field theories for hydrodynamic-like states with higher-form symmetries. These symmetries are associated with the conservation of extended objects that constitute the fluid. One example is a plasma composed of one-dimensional strings, or magnetic flux lines, whose dynamics are described by magnetohydrodynamics. I will discuss...

16. Amortized Neural Posterior Estimation for Relativistic Mean-Field Constraints on the Neutron-Star Equation of State

Talk

We present an amortized (train-once-use-many) simulation-based inference framework for constraining the nuclear equation of state of neutron stars within density-dependent relativistic mean-field models. The aim is to validate Neural Posterior Estimation (NPE) as a fast alternative to conventional nested-sampling analyses, while preserving full Bayesian posterior quantification. We benchmark...

47. Hybrid star with the NJL model using a density-dependent vector coupling

Talk

Neutron stars are objects described by the quantum chromodynamics (QCD), which predict a deconfined quark phase for high densities. It is possible that quark matter can be reached in the core of neutron star surrounded by a hadronic phase. For an hybrid star, the two solar mass neutron star constraint requires a stiff equation of state (EoS) for intermediate densities that supports a soft core...
