Evolution of discrete symmetries
Physical Review E, 2023 Symmetries are known to dictate important physical properties and can be used as a design principle in particular in wave physics, including wave structures and the resulting propagation dynamics. Local symmetries, in the sense of a symmetry that holds only in a finite domain of space, can be either the result of a self-organization process or a ...

Gravitational wave signatures from discrete flavor symmetries [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Non-Abelian discrete symmetries have been widely used to explain the patterns of lepton masses and flavor mixing. In these models, a given symmetry is assumed at a high scale and then is spontaneously broken by scalars (the flavons), which acquire vacuum

Tests of discrete symmetries in positronium decays with the J-PET detector [PDF]
EPJ Web of Conferences, 2019 As a relatively simple and purely leptonic state positronium constitutes a unique system to study discrete symmetries with precision limited only by the effects due to the weak interaction and photon-photon scattering.

The fate of discrete 1-form symmetries in 6d [PDF]
SciPost Physics, 2020 Recently introduced generalized global symmetries have been useful in order to understand non-perturbative aspects of quantum field theories in four and lower dimensions.

Metastability of Discrete-Symmetry Flocks
Physical Review Letters, 2023 We study the stability of the ordered phase of flocking models with a scalar order parameter. Using both the active Ising model and a hydrodynamic description, we show that droplets of particles moving in the direction opposite to that of the ordered phase nucleate and grow.

Proof of the universal density of charged states in QFT
Journal of High Energy Physics, 2021 We prove a recent conjecture by Harlow and Ooguri concerning a universal formula for the charged density of states in QFT at high energies for global symmetries associated with finite groups. An equivalent statement, based on the entropic order parameter

How to find discrete contact symmetries [PDF]
, 1998 This paper describes a new algorithm for determining all discrete contact symmetries of any differential equation whose Lie contact symmetries are known. The method is constructive and is easy to use.

Accidental symmetries in the 2HDMEFT
Nuclear Physics B, 2020 We construct accidentally symmetric potentials in the framework of Two Higgs Model Effective Field Theory (2HDMEFT) including higher-order operators of dimension 6 and dimension 8.

Disconnected 0-form and 2-group symmetries
Journal of High Energy Physics, 2023 Quantum field theories can have both continuous and finite 0-form symmetries. We study global symmetry structures that arise when both kinds of 0-form symmetries are present. The global structure associated to continuous 0-form symmetries is described by

Potential of the J-PET detector for studies of discrete symmetries in decays of positronium atom - a purely leptonic system [PDF]
, 2016 The Jagiellonian Positron Emission Tomograph (J-PET) was constructed as a prototype of the cost-effective scanner for the simultaneous metabolic imaging of the whole human body.
