Shadows and Thin-Disk Images of Kerr-Newman Black Holes in a Bertotti-Robinson Magnetic Field
Xi Wan, Haiyu Wang, Zhenyu Zhang +2
In this paper, we investigate the optical properties of Kerr-Newman-Bertotti-Robinson (KN-BR) black holes. We use the separability of null geodesics to analyze unstable spherical p…
Critical Behavior of Photon Rings in Kerr-Bertotti-Robinson Spacetime
Xi Wan, Zhenyu Zhang, Fang-Stars Wei +2
In this work, we investigate the critical behavior of photon rings in the Kerr-Bertotti-Robinson spacetime, describing a rotating black hole immersed in a background magnetic field…
Geodesics and Shadows in the Kerr-Bertotti-Robinson Black Hole Spacetime
Xinyu Wang, Yehui Hou, Xi Wan +2
In this work, we investigate geodesics and black hole shadows in the Kerr-Bertotti-Robinson spacetime. We show that the equations of motion for null geodesics are separable and adm…
Algebraic synthesis of time-optimal unitaries in SU(2) with alternating controls
Clarice D. Aiello, Michele Allegra, Boerge Hemmerling +2
We present an algebraic framework to study the time-optimal synthesis of arbitrary unitaries in SU(2), when the control set is restricted to rotations around two non-parallel axes…
