Weyl points on non-orientable manifolds
André Grossi Fonseca, Sachin Vaidya, Thomas Christensen +3
Weyl fermions are hypothetical chiral particles that can also manifest as excitations near three-dimensional band crossing points in lattice systems. These quasiparticles are subje…
Prevalence of two-dimensional photonic topology
Ali Ghorashi, Sachin Vaidya, Mikael Rechtsman +3
The topological characteristics of photonic crystals have been the subject of intense research in recent years. Despite this, the basic question of whether photonic band topology i…
Direct Observation of Landau Levels in Silicon Photonic Crystals
Maria Barsukova, Fabien Grisé, Zeyu Zhang +7
We experimentally observe photonic Landau levels that arise due to a strain-induced pseudomagnetic field in a silicon photonic crystal slab. The Landau levels are dispersive (i.e.,…
Response to polarization and weak topology in Chern insulators
Sachin Vaidya, Mikael C. Rechtsman, Wladimir A. Benalcazar
Chern insulators present a topological obstruction to a smooth gauge in their Bloch wave functions that prevents the construction of exponentially-localized Wannier functions - thi…
Topological Phases of Photonic Crystals under Crystalline Symmetries
Sachin Vaidya, Ali Ghorashi, Thomas Christensen +2
Photonic crystals (PhCs) have emerged as a popular platform for realizing various topological phases due to their flexibility and potential for device applications. In this article…
