Phenomenology of wavelike vector dark matter nonminimally coupled to gravity
Hong-Yi Zhang, Siyang Ling
We study three astrophysical/cosmological consequences of nonminimal couplings to gravity in wavelike vector dark matter. In the nonrelativistic limit, the nonminimal coupling with…
Beyond Schrödinger-Poisson: Nonrelativistic Effective Field Theory for Scalar Dark Matter
Borna Salehian, Hong-Yi Zhang, Mustafa A. Amin +2
Massive scalar fields provide excellent dark matter candidates, whose dynamics are often explored analytically and numerically using nonrelativistic Schrödinger-Poisson (SP) equati…
Gravitational effects on oscillon lifetimes
Hong-Yi Zhang
Many scalar field theories with attractive self-interactions support exceptionally long-lived, spatially localized and time-periodic field configurations called oscillons. A detail…
Classical Decay Rates of Oscillons
Hong-Yi Zhang, Mustafa A. Amin, Edmund J. Copeland +2
Oscillons are extremely long-lived, spatially-localized field configurations in real-valued scalar field theories that slowly lose energy via radiation of scalar waves. Before thei…
