Scalable Test of Genuine Multipartite Entanglement via Partially Randomized Measurements
Jan Wojcik, Pawel Chrabkowski, Wieslaw Laskowski
Certifying genuine multipartite entanglement in quantum systems can require a number of measurements that grows exponentially with the system size. Here we introduce a criterion ba…
A mechanical characterization of constant mean curvature surfaces
Matteo Raffaelli
The speed of a ball rolling without skidding or spinning on a surface is the length of the velocity of its center. We show that if the speed depends only on , then …
The geometric Cauchy problem for constant-rank submanifolds
Matteo Raffaelli
Given a smooth -dimensional submanifold of and a smooth distribution of rank along , we study the following geometric Cauchy problem:…
-Principles for smooth curves and knots with prescribed curvature
Mohammad Ghomi, Matteo Raffaelli
We show that smooth curves with prescribed curvature satisfy a -dense -principle in the space of immersed curves in Euclidean space. More precisely, every cu…
-Principles for curves and knots of constant torsion
Mohammad Ghomi, Matteo Raffaelli
We prove that curves of constant torsion satisfy the -dense h-principle in the space of immersed curves in Euclidean space. In particular, there exists a knot of constant tors…
Topology of closed asymptotic curves on negatively curved surfaces
Mohammad Ghomi, Matteo Raffaelli
Motivated by Nirenberg's problem on isometric rigidity of tight surfaces, we study closed asymptotic curves on negatively curved surfaces in Euclidean -space. In partic…
