Chiral Quantum Entanglement Transfer with Giant Atoms
Peng-Fei Wang, Lei Huang, Yi-Long-Yue Guo +4
We investigate entanglement transfer in a multi-giant-atom waveguide system. By tailoring chiral spontaneous emission and exploiting dark-state dynamics, the setup enables perfect,…
Imaging the Meissner effect and local superfluid stiffness in a graphene superconductor
Ruoxi Zhang, Benjamin A. Foutty, Owen Sheekey +15
We report the observation of the Meissner effect in a rhombohedral graphene superconductor, realized via direct imaging of the static fringe magnetic field. In our few-micron sampl…
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…
Ultrafast Charge-Doping via Photo-Thermionic Injection in van der Waals Devices
Yiliu Li, Esteban Rojas-Gatjens, Yinjie Guo +10
Van der Waals (vdW) heterostructures of two-dimensional (2D) materials have become a rich playground for the exploration of correlated quantum phases, and recent studies have begun…
Photoinduced Metal-to-Insulator Transitions in 2D Moiré Devices
Yiliu Li, Esteban Rojas-Gatjens, Yinjie Guo +10
Photoexcitation has been utilized to control quantum matter and to uncover metastable phases far from equilibrium. Among demonstrations to date, the most common is the photo-induce…
Supersonic flow and hydraulic jump in an electronic de Laval nozzle
Johannes Geurs, Tatiana A. Webb, Yinjie Guo +10
In very clean solid-state systems, where carrier-carrier interactions dominate over any other scattering mechanisms, the flow of electrons can be described within a hydrodynamic fr…
