چکیده
A method of Parity-Time (PT)-symmetry analysis is introduced to study the high dimensional, complicated parameter space drift wave instabilities. We show that spontaneous PT-symmetry breaking leads Ion Temperature Gradient (ITG) instability waves, and collisional result explicit breaking. new unstable induced by finite collisionality identified. It also found gradients ion temperature density can destabilize cyclotron waves when PT symmetry explicitly broken a collisionality.

Manipulating one-way space wave and its refraction by time-reversal and parity symmetry breaking
One-way transmission and negative refraction are the exotic wave properties founded in photonic crystals which attract a great attention due to their promising applications in photonic devices. How to integrate such two phenomena in one material or device is interesting and valuable. In this work, we theoretically and experimentally demonstrate that one-way electromagnetic space wave can be rea...
متن کاملExplicit Electroweak Symmetry Breaking?
We hypothesise that all electroweak symmetry breaking terms such as fermion masses and the W and Z gauge boson masses arise radiatively from just one explicit symmetry breaking term in the Lagrangian. Our hypothesis is motivated by the lack of experimental support and the lack of predictivity of the standard symmetry breaking scenario. We construct a simple model which illustrates our ideas. We...
متن کاملSpontaneous breaking of the spatial homogeneity symmetry in wave turbulence.
We report a surprising new result for wave turbulence which may have broader ramifications for general turbulence theories. Spatial homogeneity, the symmetry property that all statistical moments are functions only of the relative geometry of any configuration of points, can be spontaneously broken by the instability of the finite flux Kolmogorov-Zakharov spectrum in certain (usually one dimens...
متن کاملParity-Time Symmetry Breaking in Coupled Nanobeam Cavities.
The concept of parity-time symmetry (PT symmetry) originates from the canonical quantum mechanics and has become a hot topic recently. As a versatile platform to investigate the intriguing concept, both theoretical and experimental works in optics have been implemented. In this paper, the PT symmetry breaking phenomenon is investigated in a coupled nanobeam cavity system. An exceptional point i...
متن کاملSpontaneous Breaking of R-parity
So far most attention to the study of supersymmetric phenomenology has been made in the framework of the Minimal Supersymmetric Standard Model (MSSM) 1 with conserved R-parity . R-parity is a discrete symmetry assigned as Rp = (−1)(3B+L+2S), where L is the lepton number, B is the baryon number and S is the spin of the state. If R-parity is conserved all supersymmetric particles must always be p...
