Are there testable discrete Poincaré invariant physical theories? [PDF]
In a model of physics taking place on a discrete set of points that approximates Minkowski space, one might perhaps expect there to be an empirically identifiable preferred frame. However, the work of Dowker et al (2004 Mod. Phys. Lett. A 19 1829-40) and Bombelli et al (2009 Mod. Phys. Lett.

Scale-invariant Learning by Physics Inversion
Solving inverse problems, such as parameter estimation and optimal control, is a vital part of science. Many experiments repeatedly collect data and rely on machine learning algorithms to quickly infer solutions to the associated inverse problems.

I review the main features and some of the theoretical attempts to explain the excess around an invariant mass of 750 GeV seen in 2015 at the LHC in the di-photon channel. As this hint to new physics has now all but disappeared from the higher-luminosity

In 1969, Jean-Marie Souriau introduced a “Lie Groups Thermodynamics” in Statistical Mechanics in the framework of Geometric Mechanics. This Souriau’s model considers the statistical mechanics of dynamic systems in their “space of evolution” associated to

Weyl-invariant Einstein–Cartan gravity with a heavy ALP: Higgs inflation and α-attractors
We initiate the analysis of the inflationary dynamics in Weyl-invariant Einstein–Cartan gravity nonminimally coupled to the Standard Model of particle physics.

Breakdown of emergent Lifshitz symmetry in holographic matter with Harris-marginal disorder
We revisit the theory of strongly correlated quantum matter perturbed by Harris-marginal random-field disorder, using the simplest holographic model. We argue that for weak disorder, the ground state of the theory is not Lifshitz invariant with a non ...

The LHC di-photon excess at 750 GeV
I review the main features and some of the theoretical attempts to explain the excess around an invariant mass of 750 GeV seen in 2015 at the LHC in the di-photon channel. As this hint to new physics has now all but disappeared from the higher-luminosity

Generalized Statistics on Lattices
The statistics of particles and extended excitations, such as loops and membranes, are fundamental to modern condensed matter physics, high-energy physics, and quantum information science, yet a comprehensive lattice-level framework for computing them ...

A Nonparametric Peak Finder Algorithm and Its Application in Searches for New Physics
We have developed an algorithm for nonparametric fitting and extraction of statistically significant peaks in the presence of statistical and systematic uncertainties.

Applications of Symmetry Methods to the Theory of Plasma Physics
The theory of plasma physics offers a number of nontrivial examples of partial differential equations, which can be successfully treated with symmetry methods.
