From Feynman's ratchet to timecrystalline molecular motors
Jianmei Wang, Jin Dai, Antti J. Niemi +1
Cats use the connection governing parallel transport in the space of shapes to land safely on their feet. Here we argue that this connection also explains the impressive performanc…
Research on the transition dynamics and linear (nonlinear) optical properties of mCherry
Yuanjin Wang, Gaoshang Li, Jin Dai +2
In this study, we explore the electron transition mechanism and optical properties of the popular red fluorescent protein mCherry. By examining the charge transfer spectrum and com…
The SU(2) Lie-Poisson Algebra and its Descendants
Jin Dai, Theodora Ioannidou, Antti Niemi
In this paper, a novel discrete algebra is presented which follows by combining the SU(2) Lie-Poisson bracket with the discrete Frenet equation. Physically, the construction descri…
Vortex precession and exchange in a Bose-Einstein condensate
Julien Garaud, Jin Dai, Antti J. Niemi
Vortices in a Bose-Einstein condensate are modelled as spontaneously symmetry breaking minimum energy solutions of the time dependent Gross-Pitaevskii equation, using the method of…
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…
