In some quantum materials, which are materials governed by quantum mechanical effects, interactions between charged particles ...
A team of US researchers has unveiled a device that can conduct electricity along its fractionally charged edges without ...
He Qinglin's group at the Center for Quantum Materials Science, School of Physics, has reported the first observation of non-reciprocal Coulomb drag in Chern insulators. This breakthrough opens new ...
Peking University, April 24, 2025: He Qinglin’s group at the Center for Quantum Materials Science, School of Physics, has reported the first observation of non-reciprocal Coulomb drag in Chern ...
We present a theory of fractional Chern insulator stabilization against charge-ordered states. We argue that the phase competition is captured by an effective interaction range, which depends on both ...
Fig. 1: Schematic picture of the experimental setup showing a Chern insulator (purple) with attached electrodes (gold) and a SQUID magnetometer (shown as a loop on top of the insulator), which allows ...
