Journal of Fluid Mechanics, 2022 This article deals with the symmetry breaking of azimuthal thermoacoustic modes in annular combustors. Using a nominally symmetric annular combustor, we present experimental evidence of a predicted spontaneous reflectional symmetry breaking, and also an ...

Pseudo-spontaneous U(1) symmetry breaking in hydrodynamics and holography [PDF]
Journal of High Energy Physics, 2021 We investigate the low-energy dynamics of systems with pseudo-spontaneously broken U(1) symmetry and Goldstone phase relaxation. We construct a hydrodynamic framework which is able to capture these, in principle independent, effects.

Asymmetric balance in symmetry breaking
Physical Review Research, 2020 Spontaneous symmetry breaking is central to our understanding of physics and explains many natural phenomena, from cosmic scales to subatomic particles.

Strong-to-Weak Spontaneous Symmetry Breaking in Mixed Quantum States [PDF]
PRX QuantumSymmetry in mixed quantum states can manifest in two distinct forms: , where each individual pure state in the quantum ensemble is symmetric with the same charge, and , which applies only to the entire ensemble.

Spontaneous strong symmetry breaking in open systems: Purification perspective [PDF]
Physical review BWe explore the landscape of the decoherence effect in mixed-state ensembles from a purification perspective. We analyze the spontaneous strong-to-weak symmetry breaking (SSSB) in mixed states triggered by local quantum channels by mapping this ...

Journal of High Energy Physics, 2019 Perturbative calculations of the effective potential evaluated at a broken minimum, V min, are plagued by difficulties. It is hard to get a finite and gauge invariant result for V min.

Crystal time-reversal symmetry breaking and spontaneous Hall effect in collinear antiferromagnets [PDF]
Science Advances, 2019 Identification of a previously overlooked spontaneous Hall effect mechanism creates opportunities in low-dissipation spintronics. Electrons, commonly moving along the applied electric field, acquire in certain magnets a dissipationless transverse ...

Spontaneous symmetry breaking of arbitrage [PDF]
Physica A: Statistical Mechanics and its Applications, 2012 We introduce the concept of spontaneous symmetry breaking to arbitrage modeling. In the model, the arbitrage strategy is considered as being in the symmetry breaking phase and the phase transition between arbitrage mode and no-arbitrage mode is triggered by a control parameter.

ON THE SYMMETRY OF THE VACUUM IN THEORIES WITH "SPONTANEOUS SYMMETRY BREAKING" [PDF]
International Journal of Modern Physics A, 2011 We review the usual account of the phenomena of spontaneous symmetry breaking, pointing out the common misunderstandings surrounding the issue, in particular within the context of quantum field theory. In fact, the common explanations one finds in this context, indicate that under certain conditions corresponding to the situation called spontaneous ...

Spontaneous breaking of multipole symmetries
Physical Review B, 2022 Multipole symmetries are of interest both as a window on fracton physics and as a crucial ingredient in realizing new universality classes for quantum dynamics. Here we address the question of whether and when multipole symmetries can be spontaneously broken, both in thermal equilibrium and at zero temperature.
