Collective excitations in magnetic topological insulators and axion dark matter search
Koji Ishiwata, Kentaro Nomura
We investigate collective excitations in magnetic topological insulators (TIs) and their impact on axion detection. In the three-dimensional TI model with the Hubbard term, the eff…

Perturbative limits on axion-SU(2) gauge dynamics during inflation from the energy density of spin-2 particles
Koji Ishiwata, Eiichiro Komatsu
We investigate the conditions under which the perturbative treatment of the backreaction of spin-2 particles on the dynamics of an axion-SU(2) gauge field system breaks down during…

Supermassive black holes from inflation constrained by dark matter substructure
Shin'ichiro Ando, Shyam Balaji, Malcolm Fairbairn +2
Recent James Webb Space Telescope observations of high-redshift massive galaxy candidates have initiated renewed interest in the important mystery around the formation and evolutio…
