A Robust Strontium Tweezer Apparatus for Quantum Computing
Marijn Venderbosch, Rik van Herk, Zhichao Guo +11
Neutral atoms for quantum computing applications show promise in terms of scalability and connectivity. We demonstrate the realization of a versatile apparatus capable of stochasti…
Generalized Shift Vector as the Intrinsic Dipole of Many-Body Correlated Electronic States
Jiaming Hu, Sudipta Kundu, Zhichao Guo +4
Shift vectors play a central role in nonlinear optics and transport phenomena, where they are usually understood as charge-center shifts associated with transitions between quantum…
Giant Nonlinear Photon-Drag Currents in Moiré Bilayers
Zhuocheng Lu, Zhuang Qian, Zhichao Guo +4
The bulk photovoltaic effect provides a fundamental pathway for direct light-to-current conversion in quantum materials. However, these nonlinear currents are often strictly constr…
Dissipation-Shaped Quantum Geometry in Nonlinear Transport
Zhichao Guo, Xing-Yuan Liu, Hua Wang +2
The theory of the intrinsic nonlinear Hall effect, a key probe of quantum geometry, is plagued by conflicting expressions for the conductivity that is independent of the dissipatio…
Creation of ultracold heteronuclear p-wave Feshbach molecules
Fan Jia, Zhichao Guo, Zerong Huang +1
We report the first creation of a bulk sample of ultracold heteronuclear p-wave Feshbach molecules in an optically trapped Bose-Bose mixture of 23Na and 87Rb atoms. Using loss spec…
Acousto-optic lens for 3D shuttling of atoms in a neutral atom quantum computer
Zhichao Guo, Rik A. H. van Herk, Edgar J. D. Vredenbregt +1
We present a novel acousto-optic lens (AOL) design for neutral atom quantum computing. This approach enhances atom rearrangement in optical tweezer arrays and addresses the speed l…
