Pseudo-Critical Dynamics in First-Order Transitions [PDF]
Progress of Theoretical Physics, 1979 Simple arguments are presented about critical-like phenomena associated with first-order phase transitions in systems described by non-conserved order parameters. A mean field theory gives a type of critical phenomena near the spinodal point, which is determined by a "pseudo-free-energy" and a "pseudo-order-parameter".

Filtered pseudo-scalar dark matter and gravitational waves from first order phase transition [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Abstract If dark matter (DM) acquires mass during a first order phase transition, there will be a filtering-out effect when DM enters the expanding bubble. In this paper we study the filtering-out effect for a pseudo-scalar DM, whose mass may partially come from a first order phase transition in the hidden sector.

Non-Hermitian von Roos Hamiltonian's $\eta$-weak-pseudo-Hermiticity, isospectrality and exact solvability [PDF]
, 2007 A complexified von Roos Hamiltonian is considered and a Hermitian first-order intertwining differential operator is used to obtain the related position dependent mass $\eta$-weak-pseudo-Hermitian Hamiltonians. Using a Liouvillean-type change of variables,
