摘要：

We describe a simple method to study vortez dynamics that can determine or set an upper limit on the vortex mass. The specific heat of the vortex lattice in layered superconductors has a classical limit of 1 k(B) per pancake vortex if the vortex mass is zero. If the vortex mass m(v) is finite, a new Einstein branch of normal modes will appear with a crossover temperature Theta(E) proportional to m(v)(-1), and the specific heat will saturate at a new classical limit of 2 k(B) per pancake vortex.
