Adiabatic approach to the trans-Planckian problem in Loop Quantum Cosmology
Luis J. Garay, Mario López González, Mercedes Martín-Benito +1
We study the scalar modes that, being observable today, were trans-Planckian before inflation, within the context of hybrid Loop Quantum Cosmology (LQC). We analyse the dynamics of…
Generalized quantum Vlasov equation for particle creation and unitary dynamics
Álvaro Álvarez-Domínguez, Luis J. Garay, Mercedes Martín-Benito
The loss of time-translational invariance caused by a time-dependent external agent leads to particle creation effects in quantum field theory. This phenomenon results in ambiguiti…
Hybrid Models in Loop Quantum Cosmology
B. Elizaga Navascués, M. Martín-Benito, G. A. Mena Marugán
In the framework of Loop Quantum Cosmology, inhomogeneous models are usually quantized by means of a hybrid approach that combines loop quantization techniques with standard quantu…
Timelike information broadcasting in cosmology
Ana Blasco, Luis J. Garay, Mercedes Martin-Benito +1
We study the transmission of information and correlations through quantum fields in cosmological backgrounds. With this aim, we make use of quantum information tools to quantify th…
The Quantum Echo of the Early Universe
Ana Blasco, Luis J. Garay, Mercedes Martin-Benito +1
We show that the fluctuations of quantum fields as seen by late comoving observers are significantly influenced by the history of the early Universe, and therefore they transmit in…
Unsupervised Feature Learning for Dense Correspondences across Scenes
Chao Zhang, Chunhua Shen, Tingzhi Shen
We propose a fast, accurate matching method for estimating dense pixel correspondences across scenes. It is a challenging problem to estimate dense pixel correspondences between im…
