Universal $1 0^{20}$ Hz stochastic gravitational waves from photon spheres of black holes

Kaishu Saito, Jiro Soda, Hirotaka Yoshino

We show that photon spheres of supermassive black holes generate high-frequency stochastic gravitational waves through the photon-graviton conversion. Remarkably, the frequency is…

$O (d, d; Z)$ invariant Fierz-Pauli massive gravity

Toshifumi Noumi, Kaishu Saito, Jiro Soda +1

We consider an $O (d, d; Z)$ invariant massive deformation of double field theory at the level of free theory. We study Kaluza-Klein reduction on $R^{1, n - 1} \times T^{d}$ and…

The matrix regularization for Riemann surfaces with magnetic fluxes

Hiroyuki Adachi, Goro Ishiki, Takaki Matsumoto +1

We consider the matrix regularization of fields on a Riemann surface which couple to gauge fields with a nonvanishing magnetic flux. We show that such fields are described as recta…
