Ferromagnets, a new anomaly, instantons, and (noninvertible) continuous translations
We discuss a large class of classical field theories with continuous translation symmetry. In the quantum theory, a new anomaly explicitly breaks this translation symmetry to a discrete symmetry.

The discrete Green-Schwarz mechanism in 6D F-theory and elliptic genera of non-critical strings
We study global anomalies of discrete gauge symmetries in six-dimensional supergravities and their realizations in F-theory. We explicitly construct a discrete Green-Schwarz mechanism that depends on the choice of a coupling constant and on a certain ...

Spontaneous breaking of gauge groups to discrete symmetries
Many models of beyond Standard Model physics connect flavor symmetry with a discrete group. Having this symmetry arise spontaneously from a gauge theory maintains compatibility with quantum gravity and can be used to systematically prevent anomalies.

On discrete Lorenz attractors of various types [PDF]
The purpose of this work is to develop the theory of discrete attractors of Lorenz type in the case of three-dimensional maps. In this case, special attention will be paid to standard discrete Lorenz attractors, as well as discrete Lorenz attractors with

Condensed matter physics in time crystals
Time crystals are physical systems whose time translation symmetry is spontaneously broken. Although the spontaneous breaking of continuous time-translation symmetry in static systems is proved impossible for the equilibrium state, the discrete time ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Radiative mixing of the one Higgs boson and emergent self-interacting dark matter
In all scalar extensions of the standard model of particle interactions, the one Higgs boson responsible for electroweak symmetry breaking always mixes with other neutral scalars at tree level unless a symmetry prevents it. An unexplored important option

Goldstone bosons in different PT-regimes of non-Hermitian scalar quantum field theories
We study the interplay between spontaneously breaking global continuous and discrete antilinear symmetries in a newly proposed general class of non-Hermitian quantum field theories containing a mixture of complex and real scalar fields.

The other variants of mixed μ-τ symmetry
Two new neutrino mass matrix textures exhibiting the mixed μ-τ symmetry are proposed. The mass matrices hint for a promising neutrino mixing schemes and find their connections with Δ(27) and A4 discrete symmetry groups respectively.
