Low Residuals, Wrong Value: Learning the Viscosity Solution of Hamilton-Jacobi-Isaacs Equations with PINNs
Raul Jimenez, Pablo Tejerina-Pérez, Leonid Sarieddine +6
Physics-informed neural networks (PINNs) and other residual-trained solvers judge a candidate solution by the size of its sampled PDE residual. For first-order Hamilton-Jacobi equa…
Gravitational Duals from Equations of State II: Large Hierarchies and False Vacua
Raul Jimenez, David Mateos, Pavlos Protopapas +3
We investigate the reconstruction of holographic duals for strongly coupled quantum field theories in regimes characterized by large hierarchies and the presence of false vacua. Wi…
Recovering Sharp Conductivity Features in the Finite-Data Calderón Problem with Physics-Informed Neural Networks
Ali AlHadi Kalout, Pablo Tejerina-Pérez, Konstantin Karchev +5
Physics-informed neural networks (PINNs) have recently emerged as a promising framework for addressing the Calderón inverse problem from limited boundary data. In this work, we rev…
THFM: A Unified Video Foundation Model for 4D Human Perception and Beyond
Letian Wang, Andrei Zanfir, Eduard Gabriel Bazavan +2
We present THFM, a unified video foundation model for human-centric perception that jointly addresses dense tasks (depth, normals, segmentation, dense pose) and sparse tasks (2d/3d…
Cluster glass behavior and magnetocaloric effect in the hexagonal polymorph of disordered CePdGe
Leszek S. Litzbarski, Kamil Balcarek, Anna Bajorek +3
In this work, we study the hexagonal variant of the system that crystallizes in the -type structure (space group , ) and exhib…
Efficient PINNs via Multi-Head Unimodular Regularization of the Solutions Space
Pedro Tarancón-Álvarez, Pablo Tejerina-Pérez, Raul Jimenez +1
Non-linear differential equations are a fundamental tool to describe different phenomena in nature. However, we still lack a well-established method to tackle stiff differential eq…
An Entangled Universe
Pablo Tejerina-Pérez, Daniele Bertacca, Raul Jimenez
We propose a possible quantum signature of the early Universe that could lead to observational imprints of the quantum nature of the inflationary period. Graviton production in the…
Gravitational Duals from Equations of State
Yago Bea, Raul Jimenez, David Mateos +4
Holography relates gravitational theories in five dimensions to four-dimensional quantum field theories in flat space. Under this map, the equation of state of the field theory is…
