We study the impact of finite-temperature effects in numerical-relativity simulations of binary neutron star mergers with microphysical equations of state and neutrino transport in which we vary the effective nucleon masses in a controlled way. We find that, as the specific heat is increased, the merger remnants become colder and more compact due to the reduced thermal pressure support. Using a full Bayesian analysis, we demonstrate that this effect will be measurable in the postmerger gravitational wave signal with next-generation observatories at signal-to-noise ratios of 15.

  1. Coherent State Path Integral Reveals Unexpected Vacuum Structure in Thermal Field Theory

    hep-th 2025-07 reject novelty 3.0 of 10

    A coherent-state derivation of the thermal partition function yields extra vacuum and mass-coupling terms that the authors claim are novel, though these terms reflect the chosen operator ordering.
