Equatorial Waves in Rotating Bubble-Trapped Superfluids
Guangyao Li, Dmitry K. Efimkin
As the Earth rotates, the Coriolis force causes several oceanic and atmospheric waves to be trapped along the equator, including Kelvin, Yanai, Rossby, and Poincaré modes. It has b…
Microscopic calculation of polariton scattering in semiconductor microcavities
Guangyao Li, Meera M. Parish, Jesper Levinsen
Recent experiments in exciton-polariton systems have provided high-precision measurements of the value of the polariton-polariton interaction constant, which is a key parameter tha…
Theory of polariton-electron interactions in semiconductor microcavities
Guangyao Li, Olivier Bleu, Jesper Levinsen +1
We develop a microscopic description of an electron-doped two-dimensional semiconductor embedded in a microcavity. Specifically, we investigate the interactions between exciton-pol…
Enhanced scattering between electrons and exciton-polaritons in a microcavity
Guangyao Li, Olivier Bleu, Meera M. Parish +1
The interplay between strong light-matter interactions and charge doping represents an important frontier in the pursuit of exotic many-body physics and optoelectronics. Here, we c…
Polariton interactions in microcavities with atomically thin semiconductor layers
O. Bleu, G. Li, J. Levinsen +1
We investigate the interactions between exciton-polaritons in N two-dimensional semiconductor layers embedded in a planar microcavity. In the limit of low-energy scattering, where…
Microscopic description of exciton-polaritons in microcavities
Jesper Levinsen, Guangyao Li, Meera M. Parish
We investigate the microscopic description of exciton-polaritons that involves electrons, holes and photons within a two-dimensional microcavity. We show that in order to recover t…
The Design for a Nanoscale Single-Photon Spin Splitter
G. Li, A. S. Sheremet, R. Ge +2
We propose using the effective spin-orbit interaction of light in Bragg-modulated cylindrical waveguides for the effcient separation of spin-up and spin-down photons emitted by a s…
Talbot effect for exciton-polaritons
T. Gao, E. Estrecho, G. Li +8
We demonstrate, experimentally and theoretically, a Talbot effect for hybrid light-matter waves -- exciton-polariton condensate formed in a semiconductor microcavity with embedded…
Azimuthons and pattern formation in annularly confined exciton-polariton Bose-Einstein condensates
Guangyao Li
We present numerical analysis of steady states in a two-component (spinor) driven-dissipative quantum fluid formed by condensed exciton-polaritons in an annular optically induced t…
Incoherent excitation and switching of spin states in exciton-polariton condensates
G. Li, T. C. H. Liew, O. A. Egorov +1
We investigate, theoretically and numerically, the spin dynamics of a two-component exciton-polariton condensate created and sustained by non-resonant spin-polarized optical pumpin…
Stability of persistent currents in open-dissipative quantum fluids
Guangyao Li, Michael D. Fraser, Alexander Yakimenko +1
The phenomenon of stable persistent currents is central to the studies of superfluidity in a range of physical systems. While all of the previous theoretical studies of superfluid…
Creation of orbital angular momentum states with chiral polaritonic lenses
Robert Dall, Michael D. Fraser, Anton S. Desyatnikov +6
Controlled transfer of orbital angular momentum to exciton-polariton Bose-Einstein condensate spontaneously created under incoherent, off-resonant excitation conditions is a long-s…
