Z_2 Photonic topological insulators in the visible wavelength range for robust nanoscale photonics
Wenjing Liu, Minsoo Hwang, Zhurun Ji +3
Topological photonics provides an ideal platform for demonstrating novel band topology concepts, which are also promising for robust waveguiding, communication and computation appl…
Room-temperature polariton lasing in quantum heterostructure nanocavities
Jang-Won Kang, Bokyung Song, Wenjing Liu +3
Controlling light-matter interactions in solid-state systems has motivated intense research to produce bosonic quasi-particles known as exciton-polaritons, which requires strong co…
Observation and active control of a collective polariton mode and polaritonic band gap in few-layer WS2 strongly coupled with plasmonic lattices
Wenjing Liu, Yuhui Wang, Biyuan Zheng +7
Two-dimensional semiconductors host excitons with very large oscillator strengths and binding energies due to significantly reduced carrier screening. Two-dimensional semiconductor…
Spatially dispersive circular photogalvanic effect in a Weyl semimetal
Zhurun Ji, Gerui Liu, Zachariah Addison +8
Weyl semimetals are gapless topological states of matter with broken inversion and/or time reversal symmetry, which can support unconventional responses to externally applied elect…
Understanding the different exciton-plasmon coupling regimes in two-dimensional semiconductors coupled with plasmonic lattices: a combined experimental and unified equations of motion approach
Wenjing Liu, Yuhui Wang, Carl H. Naylor +6
We study exciton-plasmon coupling in two-dimensional semiconductors coupled with Ag plasmonic lattices via angle-resolved reflectance spectroscopy and by solving the equations of m…
