Interband Berry connection measurement in the optical honeycomb lattice
Shao-Wen Chang, Malte N. Schwarz, Erin G. Moloney +2
The geometry of Bloch bands affects many physical properties of crystalline solids and other spatially periodic systems. Direct experimental determination of such geometry is an ac…
Direct Geometric Probe of Singularities in Band Structure
Charles D. Brown, Shao-Wen Chang, Malte N. Schwarz +5
The band structure of a crystal may have points where two or more bands are degenerate in energy and where the geometry of the Bloch state manifold is singular, with consequences f…
Interaction-Enhanced Group Velocity of Bosons in the Flat Band of an Optical Kagome Lattice
Tsz-Him Leung, Malte N. Schwarz, Shao-Wen Chang +3
Geometric frustration of particle motion in a kagome lattice causes the single-particle band structure to have a flat s-orbital band. We probe this band structure by exciting a Bos…
