Dark magnetohydrodynamics: Black hole accretion in superradiant dark photon clouds
Shuo Xin, Elias R. Most
Black holes threaded by massive vector fields can be subject to a superradiant instability, growing a cloud of massive vector particles around it. In this work, we consider what ha…

On the Origin of Acoustic Spin and Elastic Spin: Uncovering Hidden Wave Spin of Scalar Fields with Higher-Order Derivative Lagrangian
Shuo Xin, Jie Ren
Scalar field should have no spin angular momentum according to conventional understandings in classical field theory. Yet, recent studies demonstrate the undoubted existence of wav…
