Quantum Geometry Set a Limit on Repulsion
New bounds constrain how strongly two-dimensional plates can repel and point flat Chern bands toward shorter crossover distances.
Summary
New bounds constrain how strongly two-dimensional plates can repel and point flat Chern bands toward shorter crossover distances.
The analysis connects the sign and magnitude of long-range Casimir forces to the quantum geometric tensor. It limits the benefit of simply increasing Chern number and predicts that flat Chern bands can widen the repulsive regime and move it toward more accessible distances, with twisted molybdenum ditelluride offered as one platform. The result is a theoretical optimization map, not an experimental force measurement.
Why it matters
