Counterdirectional Exciton and Trion Motion in Applied Electric Field
Daniel Vaz, Yuanjun Guan, Qiaochu Wan +13
Charged excitonic complexes are central to the optoelectronic and many-body properties of semiconductors, yet their real-space transport dynamics remain largely unexplored. Here, w…
Long-Range Fermi-Polaron Blockade in Monolayer MoSe
Jonas Peterson, Shibalik Lahiri, Monique Tie +10
Strong optical nonlinearities at the few-photon level are a central goal for quantum photonics, yet they remain difficult to realize in solid-state systems. In doped two-dimensiona…
Optical signatures of antiferromagnetic correlations in a strongly interacting quantum Hall MoSe2 monolayer
Jiho Sung, Pavel A. Volkov, Ilya Esterlis +9
Strong magnetic fields quench the kinetic energy of electrons, leading to the formation of flat energy bands, known as Landau levels (LLs). In this situation, even weak interaction…
Magnetic Signatures of a Putative Fractional Topological Insulator in Twisted MoTe2
Yiping Wang, Gillian E. Minarik, Weijie Li +15
The interplay among electronic correlation, topology, and time-reversal-symmetry (TRS) often leads to exotic quantum states of matter, as highlighted by the discoveries of fraction…
Pre-Patterned Superconducting Contacts for Clean Superconductor-Topological Material Interfaces Enabling Long-Range Josephson Coupling
Yong-Bin Choi, Chang-Won Choi, Luke Holtzman +8
Phase-coherent superconducting proximity in topological materials requires clean superconductor-topological material (SC-TM) interfaces, yet conventional top-contact fabrication of…
Angle evolution of the superconducting phase diagram in twisted bilayer WSe2
Yinjie Guo, John Cenker, Ammon Fischer +13
Recent observations of superconductivity in twisted bilayer WSe have extended the family of moiré superconductors beyond twisted graphene. In WSe two different twist angle…
