Statistics of an Unstable Barotropic Jet from a Cumulant Expansion
Low-order equal-time statistics of a barotropic flow on a rotating sphere are investigated. The flow is driven by linear relaxation toward an unstable zonal jet. For relatively short relaxation
Topological origin of equatorial waves
A topological origin is shown for two well-known equatorially trapped waves, the Kelvin and Yanai modes, owing to the breaking of time-reversal symmetry by Earth's rotation, which demonstrates that ocean and atmospheric waves share fundamental properties with topological insulators and that topology plays an unexpected role in Earth's climate system.
Direct statistical simulation of out-of-equilibrium jets.
It is shown that, for jets near equilibrium, CE2 is capable of reproducing the jet structure (although some differences remain in the second cumulant), but as the degree of departure from equilibrium is increased (as measured by the zonostrophy parameter), the jets meander more and CE2 becomes less accurate.
In this paper, we introduce the concept of direct statistical simulation for astrophysical flows. This technique may be appropriate for problems in astrophysical fluids where the instantaneous
Generalized Quasilinear Approximation: Application to Zonal Jets.
This work presents a generalization of quasilinear theory to include dynamic mode interactions on the large scales by separating the state variables into large and small zonal scales via a spectral filter rather than by a decomposition into a formal mean and fluctuations.
Spin quantum Hall effect in unconventional superconductors
We study the properties of the ‘‘spin quantum Hall fluid’’—a spin phase with quantized spin Hall conductance that is potentially realizable in superconducting systems with unconventional pairing
Three-dimensional rotating Couette flow via the generalised quasilinear approximation
We examine the effectiveness of the generalised quasilinear (GQL) approximation introduced by Marston et al. (Phys. Rev. Lett., vol. 116 (21), 2016, 214501). This approximation splits the variables
Spin‐Peierls and spin‐liquid phases of Kagomé quantum antiferromagnets
The ground state of the spin‐1/2 nearest‐neighbor Heisenberg quantum antiferromagnet on the Kagome lattice probably lacks spin order; therefore, conventional spin‐wave analysis breaks down. To
Transport anomalies in a simplified model for a heavy-electron quantum critical point
We discuss the transport anomalies associated with the development of heavy electrons out of a neutral spin fluid using the large-N treatment of the Kondo-Heisenberg lattice model. At the phase

Planetary atmospheres, and models of them, are discussed from the viewpoint of condensed matter physics. Atmospheres are a form of condensed matter, and many of the most interesting concepts of
