Field localisation and spin-momentum locking in zero-dimensional dissipative topological photonic interface state

Aidan H. Y. Chong, Y. Q. Liu, C. Liu +1

Topological photonic systems support edge states that are robust against disorder and perturbation. Depending on the symmetry and dimensionality of the bulk systems, different edge…

Evolution of spin excitations in superconducting La $_{2 - x}$ Ca $_{x}$ CuO $_{4 - I^´}$ from the underdoped to the heavily overdoped regime

S. Hameed, Y. Liu, M. Knauft +8

We investigate high-energy spin excitations in hole-doped La $_{2 - x}$ Ca $_{x}$ CuO $_{4 - I^´}$ films across a broad Ca doping range $x = 0.05 - 0.50$ using resonant inelastic x-ray scatter…

Pervasive symmetry-lowering nanoscale structural fluctuations in the cuprate La $_{2 - x}$ Sr $_{x}$ CuO $_{4}$

R. J. Spieker, M. SpaiÄ, I. Khayr +12

The cuprate superconductors are among the most widely studied quantum materials, yet there remain fundamental open questions regarding their electronic properties and the role of t…
