Exceptional points in oligomer chains
C. A. Downing, V. A. Saroka
Symmetry underpins our understanding of physical law. Open systems, those in contact with their environment, can provide a platform to explore parity-time symmetry. While classical…

Non-reciprocal population dynamics in a quantum trimer
C. A. Downing, D. Zueco
We study a quantum trimer of coupled two-level systems beyond the single-excitation sector, where the coherent coupling constants are ornamented by a complex phase. Accounting for…

Doublons, topology and interactions in a one-dimensional lattice
P. Martínez Azcona, C. A. Downing
We investigate theoretically the Bose-Hubbard version of the celebrated Su-Schrieffer-Heeger topological model, which essentially describes a one-dimensional dimerized array of cou…
