The modular Dirac equation
C. Rugina
We introduce a new equation we dubbed the modular Dirac equation to see and reconstruct a spin 1/2 particle at the center of a nearly spacetime in the entanglement wedge re…
The Counterfactual Photoelectric Effect
A. Ludu, J. A. Morris, C. Rugina
We explore a counterfactual protocol for energy transfer. A modified version of a Mach-Zehnder interferometer dissociates a photon's position and energy into separate channels, res…
Non-compact manifolds with Killing spinors
C. Rugina, A. Ludu
We present a result for non-compact manifolds with invertible Dirac operator, where we link the presence of a massless Killing spinor, with a harmonic, closed conformal Killing-Yan…
Hidden symmetries and Killing spinor of 5-dimensional minimal gauged supergravity solutions
Christina Rugina
We investigate the hidden symmetries and existence of Killing spinors of D=5 minimal gauged supergravity solutions which admit a Killing-Maxwell system in the sense of Carter, such…
General Wahlquist Metrics in All Dimensions
Kazuki Hinoue, Tsuyoshi Houri, Christina Rugina +1
It is shown that the Wahlquist metric, which is a stationary, axially symmetric perfect fluid solution with , admits a rank-2 generalized closed conformal Killi…
Almost-BPS solutions in multi-center Taub-NUT
C. Rugina, A. Ludu
Microstates of colinear black holes embedded in a multi-center Taub-NUT spacetime are sought in 4 dimensions. A set of coupled ordinary partial differential equations are obtained…
Comments on the hidden symmetries of the spinning point particle in Kerr-Newman, D = 5 minimal gauged supergravity and higher dimensional spacetimes with Killing-Yano torsion
C. Rugina
We investigate the hidden symmetries of the Kerr-Newman, of the D=5 minimal gauged supergravity which admits a Killing-Maxwell system in the sense of Carter and of higher dimension…
Goryachev-Chaplygin, Kovalevskaya, and Brdička-Eardley-Nappi-Witten pp-waves spacetimes with higher rank Stäckel-Killing tensors
G. W. Gibbons, C. Rugina
Hidden symmetries of the Goryachev-Chaplygin and Kovalevskaya gyrostats spacetimes, as well as the Brdička-Eardley-Nappi-Witten pp-waves are studied. We find out that these spaceti…
