Fluid waves with topological origins Topological effects that arise from material boundaries are well known in solid-state physics and form the basis for topological insulators. Delplace et al. describe atmospheric and ocean waves that appear to have a similar topological origin (see the Perspective by Biello and Dimofte). The waves exist because of the symmetry-breaking nature of Earth's rotation, which allows certain fixed topological constraints on the system. These findings may be useful… 
Topological Waves in Astrophysical and Geophysical Flows
<p>Over the last decade, the concept of topological wave has spread over all fields of physics. These ideas were initially developed in condensed matter to describe peculiar electronic transport
A bulk-interface correspondence for equatorial waves
Topology is introducing new tools for the study of fluid waves. The existence of unidirectional Yanai and Kelvin equatorial waves has been related to a topological invariant, the Chern number, that
Odd bulk-interface correspondence in fluids
Topology is bringing new tools for the study of fluid waves. The existence of unidirectional Yanai and Kelvin equatorial waves has been related to a topological invariant, the Chern number, that
Topological transition in stratified fluids
Lamb waves are trapped acoustic-gravity waves that propagate energy over great distances along a solid boundary in density-stratified, compressible fluids1,2. They constitute useful indicators of
Topological transition in stratified atmospheres
Atmospheric Lamb waves transmit energy over great distances, and are useful indicators of volcanic eruptions, nuclear explosions or meteoritic impacts. They are trapped waves propagating along a
Topological waves in passive and active fluids on curved surfaces: a unified picture
We investigate the occurrence of topologically protected waves in classical fluids confined on curved surfaces. Using a combination of topological band theory and real space analysis, we demonstrate
Topology and broken Hermiticity
Topology and symmetry have emerged as compelling guiding principles to predict and harness the propagation of waves in natural and artificial materials. Be it for quantum particles (such as
From the geometry of Foucault pendulum to the topology of planetary waves
The physics of topological insulators makes it possible to understand and predict the existence of unidirectional waves trapped along an edge or an interface. In this review, we describe how these
Topological Langmuir-cyclotron wave
A theoretical framework is developed to describe the Topological Langmuir-Cyclotron Wave (TLCW), a recently identified topological surface excitation in magnetized plasmas. As a topological wave, the
Topological localization in out-of-equilibrium dissipative systems
TLDR
This paper reports that notions of topological protection can be applied to stationary configurations that are driven far from equilibrium by active, dissipative processes, and considers two physically disparate systems: stochastic networks governed by microscopic single-particle dynamics, and collections of driven interacting particles described by coarse-grained hydrodynamic theory.

TLDR
A broad range of experiments on Sr(2)RuO(4) that are sensitive to p-wave pairing, triplet superconductivity and time-reversal symmetry breaking are reviewed and compared to each other and to theoretical predictions, finding the evidence for triplet pairing is strong, although some puzzles remain.
Colloquium : Topological insulators
Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have protected conducting states on their edge or surface. These states are possible due to

A new theoretical mechanism is developed in which large-scale equatorial Kelvin waves can modify their speed through dispersion and interaction with other large-scale equatorial waves, such as Yanai

TLDR
Direct detection of chirality by transport measurements of electrons trapped below a free surface of 3He-A is reported, and it is shown that, at the superfluid transition, the system selected either right- or left-handed chiralities, a signature of spontaneous symmetry breaking.
