As is widely recognized in Lyapunov analysis, linearized Hamilton's equations of motion have two marginal directions for which the Lyapunov exponents vanish. Those directions are the tangent one to a Hamiltonian flow and the gradient one of the Hamil

Energy band rearrangement along a control parameter in isolated molecules is studied through axially symmetric Hamiltonians describing the coupling of two angular momenta $$\mathbf{S}$$ and $$\mathbf{L}$$ of fixed amplitude. We focus our attention on

The Dirac oscillator was initially introduced as a Dirac operator which is linear in momentum and coordinate variables. In contrast to the usual 2D Dirac oscillator, the 2D Kramers–Dirac oscillator admits the time-reversal symmetry, which is a reas

In this chapter, the equations of motion for a free rigid body are treated on the variational principle, which forms a basis for deriving the equations of motion of spatial many-body systems on the variational principle.

On the basis of the geometry, mechanics, and control studied in the previous chapters, the falling cat is modeled and analyzed to make the cat model turn a somersault under a well-designed control input.

This chapter deals with the geometric setting for planar and spatial many-body systems on the basis of connection theory. Rather, the contents of this chapter may be of practical help in understanding the connection theory.

Let ϕ and A be the scalar potential and the vector potential of the electric field E and of the magnetic flux density B, respectively; E = −∇ϕ, B = ∇×A.

We investigate the elementary rearrangements of energy bands in slow-fast one-parameter families of systems whose fast subsystem possesses a half-integer spin. Beginning with a simple case without any time-reversal symmetries, we analyze and compare
