Exciton-polariton condensate in the van der Waals magnet CrSBr
Bo Han, Hangyong Shan, Kok Wee Song +12
Van der Waals magnets are an emergent material class of paramount interest for fundamental studies in coupling light with matter excitations, which are uniquely linked to their und…
Room-temperature polariton condensate in a two-dimensional hybrid perovskite
Marti Struve, Christoph Bennenhei, Hamid Pashaei Adl +10
Layered 2D halide perovskites are chemically synthesized realizations of quantum well stacks with giant exciton oscillator strengths, tunable emission spectra and very large excito…
Femtosecond switching of strong light-matter interactions in microcavities with two-dimensional semiconductors
Armando Genco, Charalambos Louca, Cristina Cruciano +14
Ultrafast all-optical logic devices based on nonlinear light-matter interactions hold the promise to overcome the speed limitations of conventional electronic devices. Strong coupl…
Electrically tunable and enhanced nonlinearity of moiré exciton-polaritons in transition metal dichalcogenide bilayers
Kok Wee Song, Oleksandr Kyriienko
We develop a microscopic theory for nonlinear optical response of moiré exciton-polaritons in bilayers of transition metal dichalcogenides (TMDs). Our theory allows to study the tu…
Nonlinear Rydberg exciton-polaritons in CuO microcavities
Maxim Makhonin, Anthonin Delphan, Kok Wee Song +13
Rydberg excitons (analogues of Rydberg atoms in condensed matter systems) are highly excited bound electron-hole states with large Bohr radii. The interaction between them as well…
Interlayer superexchange in bilayer chromium trihalides
Kok Wee Song
We construct a microscopic model based on superexchange theory for a moiré bilayer in chromium trihalides (Cr, Br, I). In particular, we derive analytically the interlayer…
