“…The squeezing effect and SBBC are connected to the in-medium mass modification of bosons through a Bogoliubov transformation. This transformation establishes a connection between the creation (annihilation) operators of quasiparticles within the medium and their corresponding free particles [1][2][3][4][5][6][7][8][9]. The investigations of the SBBC may offer a fresh perspective for understanding the dynamic and thermal characteristics of the particle source.…”

“…The interactions between bosons and the source medium in high-energy heavy-ion collisions can cause a squeezing effect, resulting in a squeezed back-to-back correlation (SBBC) between boson and anti-boson in the particle-emitting source [1][2][3][4][5][6][7][8][9]. The squeezing effect and SBBC are connected to the in-medium mass modification of bosons through a Bogoliubov transformation.…”

This paper is devoted to studying the following fractional L 2 -critical nonlinear Schrödinger equation≥ 0 is an external potential. We obtain normalized L 2 -norm solutions of the above equation by solving the associated constraint minimization problem (1.4). It shows that there is a threshold a * > 0 such that (1.4) has minimizers for 0 < a < a * , and minimizers do not exist for any a > a * . For the case of a = a * , it gives a fact that the existence and non-existence of minimizers depend strongly on the value of V (0). Especially for V (0) = 0, we prove that minimizers occur blow-up behavior and the mass of minimizers concentrates at the origin as a ր a * . Applying implicit function theorem, the uniqueness of minimizers is also proved for a > 0 small enough.

We explore the squeezed back-to-back correlation (SBBC) and investigate how the squeezing effect influences the Hanbury-Brown–Twiss (HBT) interferometry using an expanding Gaussian source with nonzero width. The SBBC and HBT of D0 and ϕ mesons with finite in-medium widths are studied. The expanding flow of the source may enhance the SBBC strength of D0D¯0 and ϕϕ in the low momentum region but suppress the SBBC in the larger momentum region. The squeezing effect suppresses the influence of flow on the HBT radii, which is significant for two identical bosons with large pair momentum or with large mass. Due to the squeezing effect, the relationship between the HBT radii and the pair momentum exhibits nonflow behavior for the D0D0 pair. Likewise, nonflow behavior also appears in the HBT radii of ϕϕ with large pair momentum. This phenomenon may bring new insights for studying the squeezing effect.
