Power-law growth of shift current with superlattice period in flat Chern bands
Nianlong Zou, Cheng Xu, Ning Mao +1
Quantum geometry governs a wide array of physical observables in topological quantum materials. In its ideal limit, quantum geometry yields exact bounds and analytical results for…
Kohn--Luttinger Superconductivity in Flat Chern Bands
Nianlong Zou, Cheng Xu, Yafis Barlas +1
Recent observations of superconductivity near correlated topological phases in flat bands suggest a facile link between flat-band geometry and electron pairing. In this work, we re…
Observation of the Magnus Nonlinear Hall effect from Chiral Weyl Monopoles
Heda Zhang, Nikolai Peshcherenko, Ning Mao +4
The nonlinear Hall effect (NLHE) connects crystalline symmetry to quantum geometry, offering a probe of band topology beyond linear transport. While most studies have focused on th…
Sign-resolved nanoscale readout and control of hidden antiferromagnetic spin order
A. Schmid, D. Siebenkotten, D. Dai +16
Antiferromagnetic memories promise ultrafast, stray-field-free information storage. Yet perfect magnetic compensation conceals the information carrier itself: the sign of the Néel…
