| 1 | Special Issue on “Topological photonics and beyond:novel concepts and recent advances”显示文摘The discovery of topological phases and topological insulators has revolutionized several fields of natural science,including condensed matter physics,materials science,and photonics.Topological concepts have been implemented in a variety of materials and in a broad range of wave systems ranging from electronic,atomic,photonic,plasmonic,polaritonic,to microwave,acoustic,and mechanical waves. | Zhigang Chen Hrvoje Buljan Daniel Leykam | 2020 | Light(Science & Applications)2020，9，1： | 2 |
| 2 | Observation of supersymmetric pseudo-Landau levels in strained microwave graphene显示文摘Using an array of coupled microwave resonators arranged in a deformed honeycomb lattice,we experimentally observe the formation of pseudo-Landau levels in the whole crossover from vanishing to large pseudomagnetic field strengths.This result is achieved by utilising an adaptable setup in a geometry that is compatible with the pseudo-Landau levels at all field strengths.The adopted approach enables us to observe the fully formed flat-band pseudo-Landau levels spectrally as sharp peaks in the photonic density of states and image the associated wavefunctions spatially,where we provide clear evidence for a characteristic nodal structure reflecting the previously elusive supersymmetry in the underlying low-energy theory.In particular,we resolve the full sublattice polarisation of the anomalous 0th pseudo-Landau level,which reveals a deep connection to zigzag edge states in the unstrained case. | Matthieu Bellec Charles Poli Ulrich Kuhl Fabrice Mortessagne Henning Schomerus | 2020 | Light(Science & Applications)2020，9，1： | 1 |
