Dynamical and thermodynamic crossovers in the supercritical region of a holographic superfluid model
arxiv(2024)
摘要
Many physical systems, including classical fluids, present in their phase
diagram the competition between two phases that are separated by a line of
first-order phase transitions which terminates at a so-called critical point.
Despite several proposals, in the supercritical region beyond the critical
point, whether the two phases can still be distinguished and by which criterion
remain open questions. In this work, we study the thermodynamics and linear
dynamics of a holographic superfluid model with nonlinear potential terms in
the supercritical region. We identify the presence of a dynamical crossover,
akin to the liquid-like to gas-like Frenkel transition in supercritical fluids,
and we define other separation lines of thermodynamic origin based on higher
order derivatives of the free energy with respect to the charge density. Our
results highlight the universal dynamical and thermodynamic features of
supercritical systems from nuclear matter and classical fluids to superfluid
systems.
