Bosonic dark matter particles with hypothetical ultralight mass down to the order of a trillionth of an electronvolt have a de Borgolie wavelength in galactic length scales. The manifested quantum wave nature in astrophysical length scale suppresses and stabilizes the formation of small-scale structures with the uncertainty principle, and it is called fuzzy dark matter, which can be described...
The Born rule describes the probability of obtaining a specific outcome when measuring an observable of a given quantum system. As it has an intrinsic frequentist meaning, the Born rule only holds when it is possible to consider, at least in principle, many replicas of the system under examination. Hence, its use becomes delicate when dealing with systems for which having any copy is...
The equation of state (EoS) of dense nuclear matter is a basic ingredient for modeling a variety of astrophysical phenomena related to neutron stars (NSs), as core-collapse supernovae and binary neutron star (BNS) mergers. Determining the correct EoS which describes NSs is thus a fundamental problem of nuclear physics, particle physics and astrophysics, and major efforts have been made during...
Bosons of sufficiently low mass—termed 'ultralight' bosons—exhibit wavelike behaviour with wavelengths of the order of kpc, and can be described by a single coherent wavefunction. For this reason, this dark matter candidate is named 'fuzzy dark matter' (FDM). The presence of oscillations in the soliton cores within FDM simulations has been noted previously [1-3]; studies have been published on...
