Trion Hall effect in electron-hole double layers
Raghav Chaturvedi, Phuong X. Nguyen, Patrick Knüppel +4
The realization of Coulomb coupled electron-hole double layers in 2D semiconductor heterostructures has enabled the thermodynamic and transport studies of equilibrium exciton fluid…
Quantum correlations and dissipative blockade of polaritons in a tunable fiber cavity
Gian-Marco Schnüriger, Martin Kroner, Emre Togan +5
Cavity exciton--polaritons are quasiparticles that form when quantum well excitons hybridize with a cavity mode. Here, we carry out photon correlation measurements under continuous…
Spectroscopy of Wigner crystal polarons in an atomically thin semiconductor
L. Wang, F. Menzel, F. Pichler +5
Strongly interacting electrons in two-dimensional systems can spontaneously break translational symmetry, forming a periodic Wigner crystal. Although these crystals have been reali…
Simulating high-temperature superconductivity in moiré WSe2
Yiyu Xia, Zhongdong Han, Jiacheng Zhu +6
The emergence of high transition temperature (Tc) superconductivity in strongly correlated materials remains a major unsolved problem in physics. High-Tc materials, such as cuprate…
Emergence of Chern metal in a moiré Kondo lattice
Wenjin Zhao, Zui Tao, Yichi Zhang +9
A Chern metal is a two-dimensional metallic state of matter carrying chiral edge states. It can emerge as a doped Chern insulator, but theoretical studies have also predicted its e…
Bright hybrid excitons in molecularly tunable bilayer crystals
Tomojit Chowdhury, Aurélie Champagne, Patrick Knüppel +8
Bilayer crystals, built by stacking crystalline monolayers, generate interlayer potentials that govern excitonic phenomena but are constrained by fixed covalent lattices and orient…
