Classical Hamiltonian Time Crystals -- General Theory And Simple Examples
Jin Dai, Antti J. Niemi, Xubiao Peng
We focus on a Hamiltonian system with a continuous symmetry, and dynamics that takes place on a presymplectic manifold. We explain how the symmetry can become spontaneously broken…

Topologically enhanced time crystals and molecular knots
Jin Dai, Xubiao Peng, Antti J. Niemi
A time crystal is a time dependent physical system that does not reach a standstill, even in state of minimum energy. Here we show that the stability of a time crystal can be enhan…
