A phase transition for the biased tree-builder random walk
Arthur Blanc-Renaudie, Camille Cazaux, Guillaume Conchon-Kerjan +2
We consider a recent model of random walk that recursively grows the network on which it evolves, namely the Tree Builder Random Walk (TBRW). We introduce a bias …
On the Optimization of Singular Spectrum Analyses: A Pragmatic Approach
Fernando Lopes, Dominique Gibert, Vincent Courtillot +2
Singular Spectrum Analysis (SSA) occupies a prominent place in the real signal analysis toolkit alongside Fourier and Wavelet analysis. In addition to the two aforementioned analys…
Field-dependent diffeomorphisms and the transformation of surface charges between gauges
Luca Ciambelli, Marc Geiller
When studying gauge theories in the presence of boundaries, local symmetry transformations are typically classified as gauge or physical depending on whether the associated charges…
Quantum Gravity, Hydrodynamics and Emergent Cosmology: A Collection of Perspectives
Jibril Ben Achour, Dario Benedetti, Martin Bojowald +17
This collection of perspective pieces captures recent advancements and reflections from a dynamic research community dedicated to bridging quantum gravity, hydrodynamics, and emerg…
Observation of extrinsic topological phases in Floquet photonic lattices
Rajesh Asapanna, Rabih El Sokhen, Albert F. Adiyatullin +4
Discrete-step walks describe the dynamics of particles in a lattice subject to hopping or splitting events at discrete times. Despite being of primordial interest to the physics of…
The interdependence between density PDF, CMF and IMF and their relation with Mach number in simulations
Arturo Nuñez-Castiñeyra, Matthias González, Noé Brucy +3
The initial mass function (IMF) of stars and the corresponding cloud mass function (CMF), traditionally considered universal, exhibit variations that are influenced by the local en…
