Complement to thermodynamics of dyonic Taub-NUT-AdS spacetime
Robert B. Mann, Leopoldo A. Pando Zayas, Miok Park
We examine the thermodynamics of Euclidean dyonic Taub-NUT/Bolt-AdS4 black holes for a variety of horizon geometries to understand how gauge field regularity conditions influence t…
Fisher information as a probe of spacetime structure: Relativistic quantum metrology in (A)dS
Haoxing Du, Robert B. Mann
Relativistic quantum metrology studies the maximal achievable precision for estimating a physical quantity when both quantum and relativistic effects are taken into account. We stu…
Schrödinger's cat for de Sitter spacetime
Joshua Foo, Robert B. Mann, Magdalena Zych
Quantum gravity is expected to contain descriptions of semiclassical spacetime geometries in quantum superpositions. To date, no framework for modelling such superpositions has bee…
Analog Particle Production Model for General Classes of Taub-NUT Black Holes
Joshua Foo, Michael R. R. Good, Robert B. Mann
We derive a correspondence between the Hawking radiation spectra emitted from general classes of Taub-NUT black holes with that induced by the relativistic motion of an accelerated…
Unruh-DeWitt Detector Differentiation of Black Holes and Exotic Compact Objects
Bob Holdom, Robert B. Mann, Chen Zhang
We study the response of a static Unruh-DeWitt detector outside an exotic compact object (ECO) with a general reflective boundary condition in 3+1 dimensions. The horizonless ECO,…
Testing Short Distance Anisotropy in Space
Robert B. Mann, Idrus Husin, Hrishikesh Patel +3
The isotropy of space is not a logical requirement but rather is an empirical question; indeed there is suggestive evidence that universe might be anisotropic. A plausible source o…
Analytically Approximation Solution to Higher Derivative Gravity
S. N. Sajadi, Robert B. Mann, N. Riazi +1
We obtain analytical approximate black hole solutions for higher derivative gravity in the presence of Maxwell electromagnetic source. We construct near horizon and asymptotic solu…
Entanglement Amplification from Rotating Black Holes
Matthew P. G. Robbins, Laura J. Henderson, Robert B. Mann
The quantum vacuum has long been known to be characterized by field correlations between spacetime points. These correlations can be swapped with a pair of particle detectors, mode…
Holographic complexity of rotating black holes
Abdulrahim Al Balushi, Robie A. Hennigar, Hari K. Kunduri +1
Within the framework of the "complexity equals action" and "complexity equals volume" conjectures, we study the properties of holographic complexity for rotating black holes. We fo…
Range of novel black hole phase transitions via massive gravity: Triple points and N-fold reentrant phase transitions
A. Dehghani, S. H. Hendi, R. B. Mann
Massive gravities in anti-de Sitter spacetime can be viewed as effective dual field theories of different phases of condensed matter systems with broken translational symmetry such…
Quantum Detection of Inertial Frame Dragging
Wan Cong, Jiri Bicak, David Kubiznak +1
A relativistic theory of gravity like general relativity produces phenomena differing fundamentally from Newton's theory. An example, analogous to electromagnetic induction, is gra…
Unified Interacting Quark Matter and its Astrophysical Implications
Chen Zhang, Robert B. Mann
We investigate interacting quark matter (IQM), including the perturbative QCD correction and color superconductivity, for both up-down quark matter (QM) and strange quark matte…
Wigner negativity in spin- systems
Jack Davis, Meenu Kumari, Robert B. Mann +1
The nonclassicality of simple spin systems as measured by Wigner negativity is studied on a spherical phase space. Several SU(2)-covariant states with common qubit representations…
Holographic Complexity and Thermodynamic Volume
Abdulrahim Al Balushi, Robie A. Hennigar, Hari K. Kunduri +1
We study the holographic complexity conjectures for rotating black holes, uncovering a relationship between the complexity of formation and the thermodynamic volume of the black ho…

We investigate the thermodynamic properties of 3+1 dimensional black holes in asymptotically de Sitter spacetimes, conformally coupled to a real scalar field. We use a Euclidean ac…
Null Hypersurfaces in Kerr-Newman-AdS Black Hole and Super-Entropic Black Hole Spacetimes
Michael T. N. Imseis, Abdulrahim Al Balushi, Robert B. Mann
A three-dimensional light-like foliation of a spacetime geometry is one particular way of studying its light cone structure and has important applications in numerical relativity.…
Note on the thermodynamic stability of a black ring at quantum scales
Robert B. Mann, Behnam Pourhassan, Prabir Rudra
In this paper, the thermodynamic properties of a thin black ring in AdS space-time is explored when the size of the ring is comparable to quantum scales. The angular momentum to ma…
Small free field inflation in higher curvature gravity
Jose D. Edelstein, Robert B. Mann, David Vázquez Rodríguez +1
Within General Relativity, a minimally coupled scalar field governed by a quadratic potential is able to produce an accelerated expansion of the universe provided its value and exc…

Lower-dimensional Gauss-Bonnet Gravity and BTZ Black Holes
Robie A. Hennigar, David Kubiznak, Robert B. Mann +1
We consider the limit of Gauss-Bonnet gravity. We find two distinct but similar versions of the theory and obtain black hole solutions for each. For one theory the solutio…
