Quantum algorithm for collisionless Boltzmann simulation of self-gravitating systems
Soichiro Yamazaki, Fumio Uchida, Kotaro Fujisawa +2
The collisionless Boltzmann equation (CBE) is a fundamental equation that governs the dynamics of a broad range of astrophysical systems from space plasma to star clusters and gala…
New description of the scaling evolution of the cosmological magneto-hydrodynamic system
Fumio Uchida, Motoko Fujiwara, Kohei Kamada +1
We present a new description of cosmological evolution of the primordial magnetic field under the condition that it is non-helical and its energy density is larger than the kinetic…
Baryon isocurvature constraints on the primordial hypermagnetic fields
Kohei Kamada, Fumio Uchida, Jun'ichi Yokoyama
It has been pointed out that hypermagnetic helicity decay at the electroweak symmetry breaking may have produced the observed baryon asymmetry of the Universe through the chiral an…
