Spontaneous symmetry breaking in generative diffusion models
Neural Information Processing Systems, 2023Generative diffusion models have recently emerged as a leading approach for generating high-dimensional data. In this paper, we show that the dynamics of these models exhibit a spontaneous symmetry breaking phenomenon that divides the generative dynamics

In 1992, Kennedy and Tasaki constructed a non-local unitary transformation that maps between a $\mathbb{Z}_2\times \mathbb{Z}_2$ spontaneously symmetry breaking phase and the Haldane gap phase, which is a prototypical Symmetry-Protected Topological phase

Spontaneous Symmetry Breaking in Cyclo[18]Carbon.
Journal of Physical Chemistry A, 2020After experimental evidence of polyynic as the stable form of cyclo[18]carbon, in the present paper, using ab initio electronic structure calculations, we show that this result is a symmetry breaking event, consequence of Second-Order Jahn-Teller Effect.

As we have seen in Chap. 2, the gauge-invariant theories include massless gauge fields. From the viewpoint of physical applications both massless and massive gauge fields are relevant. Just adding a mass term to the Lagrangian for the gauge field is not allowed since it would lead to the violation of the gauge-invariance of the Lagrangian. Therefore, a

Spontaneous symmetry breaking in purely nonlinear fractional systems.
Chaos, 2020Spontaneous symmetry breaking, a spontaneous course of breaking the spatial symmetry (parity) of the system, is known to exist in many branches of physics, including condensed-matter physics, high-energy physics, nonlinear optics, and Bose-Einstein ...

Spontaneous chiral symmetry breaking in polar fluid–heliconical ferroelectric nematic phase
ScienceSpontaneous mirror symmetry breaking by formation of chiral structures from achiral building blocks and emergent polar order are phenomena rarely observed in fluids.

Inference: International Review of Science, 2018
Broken symmetries encompass a large number of different phenomena occurring at different scales. Édouard Brézin examines how symmetry has become central to understanding the organization of the universe.

Aqueous solutions of the achiral, monomeric, nucleobase mimics (2,4,6-triaminopyrimidine, TAP, and a cyanuric acid derivative, CyCo6) spontaneously assemble into macroscopic homochiral domains of supramolecular polymers.

Of the positive attributes of model building with T, rigidity ranks high on the list. The ability to mirror the structural features of our physical reality with flexible mathematics bespeaks more the talents of the model builder than any fundamental connection of the mathematics to reality. To lay claim to such a connection a mathematical idea must, in
