On the quantum origin of the seeds of cosmic structure
- A. Perez, H. Sahlmann, D. Sudarsky
- Physics
- 24 August 2005
The current understanding of the quantum origin of cosmic structure is discussed critically. We point out that in the existing treatments a transition from a symmetric quantum state to an…
Shortcomings in the Understanding of why Cosmological Perturbations Look Classical
- D. Sudarsky
- Physics
- 1 June 2009
There is a persistent state of confusion regarding the account of the quantum origin of the seeds of cosmological structure during inflation. The issue is the transition from the quantum…
Lorentz Invariance Violation and its Role in Quantum Gravity Phenomenology
- J. Collins, A. Perez, D. Sudarsky
- Physics
- 28 February 2006
The notion that gravitation might lead to a breakdown of standard space-time structure at small distances, and that this might affect the propagation of ordinary particles has led to a program to…
Alternative approach to the galactic dark matter problem
- U. Nucamendi, M. Salgado, D. Sudarsky
- Physics
- 14 November 2000
We discuss scenarios in which the galactic dark matter in spiral galaxies is described by a long range coherent field which settles in a stationary configuration that might account for the features…
Einstein-Yang-Mills isolated horizons: Phase space, mechanics, hair and conjectures
- Alejandro Corichi, U. Nucamendi, D. Sudarsky
- Physics
- 23 February 2000
The concept of "Isolated Horizon" has been recently used to provide a full Hamiltonian treatment of black holes. It has been applied successfully to the cases of {\it non-rotating}, {\it…
Scalar solitons in a 4-dimensional curved space-time

EXISTE UN TEOREMA CONOCIDO COMO UN TEOREMA DE VIRIAL QUE RESTRINGE LA POSIBLE EXISTENCIA DE ONDAS SOLITARIAS NO TRIVIALES, CON CAMPOS ESCALARES EN UN ESPACIO-TIEMPO PLANO CON 3 O MAS DIMENSIONES…
On spontaneous scalarization
- M. Salgado, D. Sudarsky, U. Nucamendi
- Physics
- 16 June 1998
We study in the physical frame the phenomenon of spontaneous scalarization that occurs in scalar-tensor theories of gravity for compact objects. We discuss the fact that the phenomenon occurs exactly…
