Schrödinger Symmetry in Spherically-symmetric Static Mini-superspaces with Matter Fields
Taishi Sano, Yuki Yokokura
Schrödinger symmetry has been shown to emerge in a ``fluid limit" from the full superspace to several mini-superspace models. To investigate one aspect of the robustness of this em…

Vector Horndeski black holes in nonlinear electrodynamics
Che-Yu Chen, Antonio De Felice, Shinji Tsujikawa +1
On a spherically symmetric and static background, we study the existence of linearly stable black hole (BH) solutions in nonlinear electrodynamics (NED) with a Horndeski vector-ten…

Complex scaling calculation of phase shifts for positron collisions with positive ions
Taishi Sano, Takuma Yamashita, Yasushi Kino
We present phase-shift calculations for positron collisions with positive ions using a complex scaling method (CSM). Based on the findings of this study [R. Suzuki, T. Myo, and K.…
