Mott transition in excitonic Bose polarons
E. A. Szwed, B. Vermilyea, D. J. Choksy +5
For a neutral system of positive and negative charges, such as atoms in a crystal, increasing the density causes the Mott transition from bound electrons to free electrons. The den…
Excitonic Bose-polarons in electron-hole bilayers
E. A. Szwed, B. Vermilyea, D. J. Choksy +6
Bose polarons are mobile impurities dressed by density fluctuations of a surrounding degenerate Bose gas. These many-body objects have been realized in ultracold atomic gasses and…
Long-distance decay-less spin transport in indirect excitons in a van der Waals heterostructure
Zhiwen Zhou, E. A. Szwed, D. J. Choksy +2
In addition to its fundamental interest, the long-distance spin transport with suppressed spin losses is essential for spintronic devices. However, the spin relaxation caused by sc…
Transport and localization of indirect excitons in a van der Waals heterostructure
L. H. Fowler-Gerace, Zhiwen Zhou, E. A. Szwed +2
Long lifetimes of spatially indirect excitons (IXs), also known as interlayer excitons, allow implementing both quantum exciton systems and long-range exciton transport. Van der Wa…
Fermi edge singularity in neutral electron-hole system
D. J. Choksy, E. A. Szwed, L. V. Butov +2
In neutral dense electron-hole (e-h) systems at low temperatures, theory predicts Cooper-pair-like excitons at the Fermi energy and a BCS-like exciton condensation. Optical excitat…
Voltage-controlled long-range propagation of indirect excitons in van der Waals heterostructure
L. H. Fowler-Gerace, D. J. Choksy, L. V. Butov
Indirect excitons (IXs), also known as interlayer excitons, can form the medium for excitonic devices whose operation is based on controlled propagation of excitons. A proof of pri…
Attractive and repulsive dipolar interaction in bilayers of indirect excitons
Darius Choksy, Chao Xu, Michael Fogler +3
We explore attractive dipolar interaction in indirect excitons (IXs). For one layer of IXs in a single pair of coupled quantum wells (CQW), the out-of-plane IX electric dipoles lea…
Localized bright luminescence of indirect excitons and trions in MoSe/WSe van der Waals heterostructure
E. V. Calman, L. H. Fowler-Gerace, L. V. Butov +5
Indirect excitons (IX) in semiconductor heterostructures are bosons, which can cool below the temperature of quantum degeneracy and can be effectively controlled by voltage and lig…
High-mobility indirect excitons in wide single quantum well
C. J. Dorow, M. W. Hasling, D. J. Choksy +4
Indirect excitons (IXs) are bound pairs of electrons and holes confined in spatially separated layers. We present wide single quantum well (WSQW) heterostructures with high IX mobi…
