Geometric Qubits in Programmable Atomic Trimers
Julien Garaud, Antti J. Niemi
Motivated by programmable tweezer arrays, we develop an exactly solvable shape-space theory for near-equilateral atomic trimers. The Higgs oscillator on Kendall's shape sphere give…

Local topology and perestroikas in protein structure and folding dynamics
Alexander Begun, Maxim N. Chernodub, Alexander Molochkov +1
Methods of local topology are introduced to the field of protein physics. This is achieved by explaining how the folding and unfolding processes of a globular protein alter the loc…

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…
