Higher-order topological phases with crystalline symmetries
… corner states and quantized 1/2 electronic charge localized at the corners of the lattice. The topologies in HOTIs are usually protected by crystalline symmetries. In this dissertation, we systematically study the charge fractionalization in 2D HOTIs under rotation symmetries. We find that, …

Strong correlations and topological order in one-dimensional systems
… electrons to disperse into their spin, band, and charge components. Fields also provide a means of tuning the shell-filling behavior associated with short tubes. The phenomenon of charge fractionalization is investigated in a one-dimensional ring. TLL theory predicts that momentum-resolved …

Higher-order crystalline topology in resonator circuits
… for identification - measurement of fractional charge (or fractional mode density). Both focus on rotationally symmetric systems, the first demonstrating that fractional charge manifesting at boundaries can indicate non-trivial higher-order topology, and the second demonstrating that fractional …
