Twist-induced Out-of-plane Ferroelectricity in Bilayer Hafnia
Jian Huang, Gwan Yeong Jung, Pravan Omprakash +6
Ferroelectric HfO2 is a promising candidate for next-generation memory devices due to its CMOS compatibility and ability to retain polarization at nanometer scales. However, the po…
Feedback-Enhanced Driven-Dissipative Quantum Batteries in Waveguide-QED Systems
Xian-Li Yin, Meixi Guo, Jian Huang +2
Quantum batteries (QBs), acting as energy storage devices, have potential applications in future quantum science and technology. However, the QBs inevitably losses energy due to th…
Quantum Saturation of Magnetoelectric Coupling in FeO Nanoparticles
Jian Huang, Fatemeh Aghabozorgi, Stephanie Brock
We report magnetoelectric coupling in nanoparticle assemblies that persists to temperatures over 300 times lower than in previous studies. The ME response saturates at low temperat…
Interaction-Driven Asymmetry in the Breakdown of the = 1 Quantum Hall State
Hoai Anh Ho, Jian Huang, L. N. Pfeiffer +1
We report real-time detection of longitudinal and transverse transport responses across distinct frequency bands in a ferromagnetic filling factor = 1 integer quantum Hall stat…
Topological protection revealed by real-time longitudinal and transverse studies
Anh Ho Hoai, Jian Huang, L. N. Pfeiffer +1
Topology provides an essential concept for achieving unchanged (or protected) quantum properties in the presence of perturbations. A challenge facing realistic applications is that…
