Polaritonic Chern insulators in monolayer semiconductors
Li He, Jingda Wu, Jicheng Jin +2
Systems with strong light-matter interaction opens up new avenues for studying topological phases of matter. Examples include exciton-polaritons, mixed light-matter quasiparticles,…
Floquet quadrupole photonic crystals protected by space-time symmetry
Jicheng Jin, Li He, Jian Lu +2
High-order topological phases, such as those with nontrivial quadrupole moments, protect edge states that are themselves topological insulators in lower dimensions. So far, most qu…
Observation of miniaturized bound states in the continuum with ultra-high quality factors
Zihao Chen, Xuefan Yin, Jicheng Jin +6
Light trapping is a constant pursuit in photonics because of its importance in science and technology. Many mechanisms have been explored, including the use of mirrors made of mate…
Non-Abelian Generalizations of the Hofstadter model: Spin-orbit-coupled Butterfly Pairs
Yi Yang, Bo Zhen, John D. Joannopoulos +1
The Hofstadter model, well-known for its fractal butterfly spectrum, describes two-dimensional electrons under a perpendicular magnetic field, which gives rise to the integer quant…
Quadrupole Topological Photonic Crystals
Li He, Zachariah Addison, Eugene J. Mele +1
Quadrupole topological phases, exhibiting protected boundary states that are themselves topological insulators of lower dimensions, have recently been of great interest. Extensions…
Synthesis and Observation of Non-Abelian Gauge Fields in Real Space
Yi Yang, Chao Peng, Di Zhu +4
Gauge fields, real or synthetic, are crucial for understanding and manipulation of physical systems. The associated geometric phases can be measured, for example, from the Aharonov…
