Environmental phenomena – including the weather – involve flows of various fluids. Many industrial processes involve flows of fluidswhetherwithin large-scale plants such as oil refineries or micro and nano fluidics, e.g. in ‘laboratory on a chip’ devices. But such flows of matter are also encountered in less familiar contexts such as in cosmology and in elementary particle physics – quark-gluon plasmas. Given such a breadth of contexts, there is a major challenge in finding accurate and… Expand
Geometry and Topology Tango in Chiral Materials
Among all symmetries constraining topological band spectra, chiral symmetry is very distinguishable. It is naturally realized as a sublattice symmetry in a host of physical systems as diverse asExpand
Emergent dual topology in the three-dimensional Kane-Mele Pt2HgSe3
Recently, the very first large-gap Kane-Mele quantum spin Hall insulator was predicted to be monolayer jacutingaite (Pt$_2$HgSe$_3$), a naturally-occurring exfoliable mineral discovered in Brazil inExpand
Magnetoelectric effect of a conducting sphere near a planar topological insulator
When time-reversal symmetry is broken on its surface, topological insulators exhibit a magnetoelectric response which is described by axion electrodynamics. A direct consequence of this theory is theExpand
Topological photonic Tamm states and the Su-Schrieffer-Heeger model
In this paper we study the formation of topological Tamm states at the interface between a semi-infinite one-dimensional photonic-crystal and a metal. We show that when the system is topologicallyExpand
Axion coupling in the hybrid Wannier representation
Many magnetic point-group symmetries induce a topological classification on crystalline insulators, dividing them into those that have a nonzero quantized Chern-Simons magnetoelectric couplingExpand
Robust topology in quench dynamics simulated on near-term quantum computers
Programmable quantum processors are suitable platforms for simulating quantum systems, of which topological phases are of particular interest. We simulate the quench dynamics of a one-dimensionalExpand
Gapless hinge states from adiabatic pumping of axion coupling
This work studies the general features of electronic states at the boundary of an insulator undergoing a cyclic evolution with a nonzero second Chern number. The figure combines two maps of FermiExpand
Location and topology of the fundamental gap in photonic crystals
The fundamental, or first, band gap is of unmatched importance in the study of photonic crystals. Here, we address precisely where this gap can be opened in the band structure of three-dimensionalExpand
Flatbands and Localization in Moiré Superlattice of Bilayer Photonic crystal
We investigate the physics of the photonic band structures of the moiré patterns that emerged when overlapping two mismatched period uni-dimensional (1D) photonic crystal slabs. The band structure ofExpand
