Testing the mean field theory of scalar field dark matter
Andrew Eberhardt, Alvaro Zamora, Michael Kopp +1
Scalar field dark matter offers an interesting alternative to the traditional WIMP dark matter picture. Astrophysical and cosmological simulations are useful to constraining the ma…
When quantum corrections alter the predictions of classical field theory for scalar field dark matter
Andrew Eberhardt, Michael Kopp, Tom Abel
We investigate the timescale on which quantum corrections alter the predictions of classical field theory for scalar field dark matter. This is accomplished by including second ord…
Diffusion evolution of a pore in bounded particle in a hydrogen atmosphere
M. I. Kopp, P. N. Ostapchuk, V. V. Yanovsky
The problem of the diffusion evolution of a pore filled with molecular hydrogen in a spherical granule in a hydrogen medium is solved. The initial position of the pore is displaced…
Field moment expansion method for interacting Bosonic systems
Andrew Eberhardt, Michael Kopp, Alvaro Zamora +1
We introduce a numerical method and python package, https://github.com/andillio/CHiMES, that simulates quantum systems initially well approximated by mean field theory using a seco…
Nonclassicality of axion-like dark matter through gravitational self-interactions
Michael Kopp, Vasileios Fragkos, Igor Pikovski
Axion-like particles (ALPs) are promising dark matter candidates. They are typically described by a classical field, motivated by large phase space occupation numbers. Here we show…
Generation of magnetic fields by thermomagnetic effects in a nonuniformly rotating layer of an electrically conductive fluid
M. I. Kopp, K. N. Kulik, A. V. Tur +1
In this paper, the generation of magnetic fields in a nonuniformly rotating layer of finite thickness of an electrically conducting fluid by thermomagnetic (TM) instability. This i…
