Gauge invariance and anomalies in condensed matter physics
Journal of Mathematical Physics, 2023 This paper begins with a summary of a powerful formalism for the study of electronic states in condensed matter physics called “gauge theory of states/phases of matter.” The chiral anomaly, which plays quite a prominent role in that formalism, is recalled.

Scaling Symmetries and Conservation Laws for Variable-coefficients Nonlinear Dispersive Equations
Trends in Computational and Applied Mathematics, 2019 Scaling symmetries arise in different branches of physics, and symmetry-based approaches are powerful tools for studying scaling-invariant models since they can provide conservation laws that are not obvious by inspection.

The general invariance of physical laws
, 2017 Physical laws are a set of rules in the relationship between observations made by the experimenter. All these observations are made through a mechanism that links the external world to the experimenter's awareness, a mechanism which is not under the experimenter's control.

Conformal inversion and Maxwell field invariants in four- and six-dimensional spacetimes
, 2014 Conformally compactified (3+1)-dimensional Minkowski spacetime may be identified with the projective light cone in (4+2)-dimensional spacetime. In the latter spacetime the special conformal group acts via rotations and boosts, and conformal inversion ...

Chiral fluids: a few theoretical issues
EPJ Web of Conferences, 2018 We review briefly a few topic concerning physics of fluids whose constituents are massless fermions interacting in chiral invariant way. Macroscopic manifestations of the chral anomaly is one of central issues.

The Global Higgs Picture at 27 TeV
SciPost Physics, 2019 We estimate the reach of global Higgs analyses at a 27 TeV hadron collider in terms of Higgs couplings and in terms of a gauge-invariant effective Lagrangian, including invisible Higgs decays and the Higgs self-coupling.
