Non-Abelian Gauge Field Mechanics
Ivan Velkovsky, Carlos Camacho, Tomoki Ozawa +2
Non-Abelian gauge fields play a key role in describing the behavior of particles whose motion is coupled to internal degrees of freedom, such as their spin. Here, we experimentally…

Observation of chiral solitary waves in a nonlinear Aharonov-Bohm ring
Ivan Velkovsky, Anya Abraham, Enrico Martello +7
Nonlinearities can have a profound influence on the dynamics and equilibrium properties of discrete lattice systems. The simple case of two coupled modes with self-nonlinearities g…

Interaction-driven breakdown of Aharonov--Bohm caging in flat-band Rydberg lattices
Tao Chen, Chenxi Huang, Ivan Velkovsky +4
Flat bands play a central role in hosting emergent states of matter in many condensed matter systems, from the nascent insulating states of twisted bilayer graphene to the fraction…
