How do CPT-like symmetries shape the stability of geophysical flows?
Tomos W. David, Pierre Delplace, Antoine Venaille
We examine the role discrete symmetries, time-reversal and mirror symmetries, play in the context of geophysical waves and instabilities. By looking at three special cases from the…
Quantized Berry winding from an emergent symmetry
Thibaud Louvet, Pierre Delplace, Mark Oliver Goerbig +1
Linear crossing of energy bands occur in a wide variety of materials. In this paper we address the question of the quantization of the Berry winding characterizing the topology of…
Berry-Chern monopoles and spectral flows
Pierre Delplace
This lecture note adresses the correspondence between spectral flows, often associated to unidirectional modes, and Chern numbers associated to degeneracy points. The notions of to…
Unidirectional modes induced by nontraditional Coriolis force in stratified fluids
Nicolas Perez, Pierre Delplace, Antoine Venaille
Using topology, we unveil the existence of new unidirectional modes in compressible rotating stratified fluids. We relate their emergence to the breaking of time-reversal symmetry…
Topological power pumping in quantum circuits
Jacquelin Luneau, Clément Dutreix, Quentin Ficheux +4
In this article, we develop a description of topological pumps as slow classical dynamical variables coupled by a quantum system. We discuss the cases of quantum Hall pumps, Thoule…
Nonlinear edge modes from topological 1D lattices
Lucien Jezequel, Pierre Delplace
We propose a method to address the existence of topological edge modes in one-dimensional (1D) nonlinearlattices, by deforming the edge modes of linearized models into solutions of…
