Intrinsic alignments of galaxies in the MassiveBlack-II simulation: analysis of two-point statistics [PDF]

, 2015
The intrinsic alignment of galaxies with the large-scale density field is an important astrophysical contaminant in upcoming weak lensing surveys. We present detailed measurements of the galaxy intrinsic alignments and associated ellipticity-direction ...

Static Observers in Curved Spaces and Non-inertial Frames in Minkowski Spacetime [PDF]

, 2010
Static observers in curved spacetimes may interpret their proper acceleration as the opposite of a local gravitational field (in the Newtonian sense).

Covariant Generalisation of Codazzi-Raychaudhuri and Area Change Equations for Relativistic Branes [PDF]

, 1997
In this paper we derive the generalisations of Gauss-Codazzi, Raychaudhuri and area change equations for classical relativistic branes and multidimensional fluids in arbitrary background manifolds with metricity and torsion.

“Squashed entanglement”: An additive entanglement measure [PDF]

, 2003
In this paper, we present a new entanglement monotone for bipartite quantum states. Its definition is inspired by the so-called intrinsic information of classical cryptography and is given by the halved minimum quantum conditional mutual information over

Monoids, Embedding Functors and Quantum Groups [PDF]

, 2007
We show that the left regular representation \pi_l of a discrete quantum group (A,\Delta) has the absorbing property and forms a monoid (\pi_l,\tilde{m},\tilde{\eta}) in the representation category Rep(A,\Delta).

Geometry of Carrollian stretched horizons [PDF]

Classical and quantum gravity
In this paper, we present a comprehensive toolbox for studying Carrollian stretched horizons, encompassing their geometry, dynamics, symplectic geometry, symmetries, and corresponding Noether charges.

Towards an Intrinsic Definition of Robustness for a Classifier [PDF]

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2020
Finding good measures of robustness – i.e. the ability to correctly classify corrupted input signals – of a trained classifier is an important question for sensitive practical applications.

Strings in gravity with torsion [PDF]

, 1999
A theory of gravitation in 4D is presented with strings used in the material action in $U_4$ spacetime. It is shown that the string naturally gives rise to torsion.

The Smarr formula within the Geroch-Held-Penrose formalism [PDF]

Classical and quantum gravity
The connection between classical thermodynamics and black hole horizons is a fundamental topic in gravitational physics, offering a potential pathway to understanding quantum aspects of gravity.

A Stress Tensor for Anti-de Sitter Gravity [PDF]

, 1999
We propose a procedure for computing the boundary stress tensor associated with a gravitating system in asymptotically anti-de Sitter space. Our definition is free of ambiguities encountered by previous attempts, and correctly reproduces the masses and ...
