Rotation by shape change, autonomous molecular motors and effective timecrystalline dynamics
Xubiao Peng, Jin Dai, Antti J. Niemi
A deformable body can rotate even with no angular momentum, simply by changing its shape. A good example is a falling cat, how it maneuvers in air to land on its feet. Here a first…
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…
Provenance of classical Hamiltonian time crystals
Anton Alekseev, Dai Jin, Antti J. Niemi
Classical Hamiltonian systems with conserved charges and those with constraints often describe dynamics on a pre-symplectic manifold. Here we show that a pre-symplectic manifold is…
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…
Can all-atom protein dynamics be reconstructed from the knowledge of C-alpha time evolution?
Jiaojiao Liu, Jin Dai, Jianfeng He +2
We inquire to what extent protein peptide plane and side chain dynamics can be reconstructed from knowledge of C-alpha dynamics. Due to lack of experimental data we analyze all ato…
Truncated Dynamics, Ring Molecules and Mechanical Time Crystals
Dai Jin, Antti J. Niemi, Xubiao Peng +1
In applications of mechanics, including quantum mechanics, we often consider complex systems, where complete solutions of the underlying "fundamental" equations is both impractical…
