Tunable Resonant Metasurfaces Empowered by Atomically Thin Semiconductors
Alexey Ustinov, Ángela Barreda, Duk-Yong Choi +4
Nanophotonics has recently gained new momentum with the emergence of a novel class of nanophotonic systems consisting of resonant dielectric nanostructures integrated with single o…
Direct measurement of broken time-reversal symmetry in centrosymmetric and non-centrosymmetric atomically thin crystals with nonlinear Kerr rotation
Florentine Friedrich, Paul Herrmann, Shridhar Sanjay Shanbhag +3
Time-reversal symmetry, together with space-inversion symmetry, is one of the defining properties of crystals, underlying phenomena such as magnetism, topology and non-trivial spin…
The role of Berry curvature derivatives in the optical activity of time-invariant crystals
Giancarlo Soavi, Jan Wilhelm
Quantum geometry and topology are fundamental concepts of modern condensed matter physics, underpinning phenomena ranging from the quantum Hall effect to protected surface states.…
Intrinsically chiral exciton polaritons in an atomically-thin semiconductor
Matthias J. Wurdack, Ivan Iorsh, Sarka Vavreckova +15
Photonic bound states in the continuum (BICs) have emerged as a versatile tool for enhancing light-matter interactions by strongly confining light fields. Chiral BICs are photonic…
