Multipolar static tidal response of Schwarzschild black holes in cubic gravity: a metric-action derivation of tidal running
Edilberto O. Silva
Static tidal Love numbers of four-dimensional Schwarzschild black holes vanish in general relativity, whereas higher-curvature interactions can generate a nontrivial response. We i…
Geometry-induced Casimir response in a helicoidal spacetime
Edilberto O. Silva
We investigate the Casimir response of a massive scalar field in a torsionless helicoidal spacetime with Levi-Civita connection. The background is ultrastatic and curved, with scal…
Dirac oscillator in a helically twisted spacetime with axial torsion
Matheus D. Moro, Fabiano M. Andrade, Faizuddin Ahmed +1
We investigate the Dirac oscillator in a helically twisted spacetime endowed with a uniform axial torsion. Starting from an orthonormal coframe, we compute the Levi--Civita spin co…
Fixed-quadrupole static tidal response of Schwarzschild black holes in a cubic Weyl effective field theory
Edilberto O. Silva
Static Love numbers of four-dimensional Schwarzschild black holes vanish in general relativity. We study how the fixed-quadrupole static tidal solution is modified by the parity-ev…
Source-driven torsional optical activity in geometrically chiral media
Edilberto O. Silva
We develop an effective field-theoretical model for source-driven electromagnetic waves in a geometrically chiral optical medium described by a uniform axial torsion. Starting from…
Dark-Soliton Branch Blocking in Transonic Bose--Einstein Condensate Flows
Edilberto O. Silva
Acoustic horizons in Bose--Einstein condensates are usually characterized through long-wavelength Bogoliubov phonons. We study a nonlinear counterpart: whether a one-dimensional da…
