Quantum Otto engine driven by quantum fields
Kensuke Gallock-Yoshimura, Vaishant Thakur, Robert B. Mann
We consider a quantum Otto engine using an Unruh-DeWitt particle detector model which interacts with a quantum scalar field in curved spacetime. We express a generic condition for…
Black hole solutions to Einstein-Bel-Robinson gravity
S. N. Sajadi, Robert B. Mann, H. Sheikhahmadi +1
In this paper, we study the physical properties of black holes in the framework of the recently proposed Einstien-Bel-Robinson gravity. We show that interestingly the theory propag…
Signatures of discretization in quantum black hole spectra
Joshua Foo, Robert B. Mann, Magdalena Zych
The quantum superposition principle states that quantum-mechanical systems such as atoms can be placed in a superposition of mass-energy eigenstates. Inspired by this idea and the…
Dynamic behaviours of black hole phase transitions near quadruple points
Jiayue Yang, Robert B. Mann
Treating the horizon radius as an order parameter in a thermal fluctuation, the free energy landscape model sheds light on the dynamic behaviour of black hole phase transitions. He…
Static spheres around spherically symmetric black hole spacetime
Shao-Wen Wei, Yu-Peng Zhang, Yu-Xiao Liu +1
Unique features of particle orbits produce novel signatures of gravitational observable phenomena, and are quite useful in testing compact astrophysical objects in general relativi…
Slowly Rotating Black Holes in Einsteinian Quartic Gravities
Gareth Arturo Marks, Robert B. Mann, Damian Sheppard
We study slowly rotating black hole solutions in the six independent theories of Einstein Quartic Gravity (EQG) in four dimensions. Unlike in the static case for which all six theo…
