Artificial Magnetic Fields in Momentum Space in Spin-Orbit Coupled Systems
Hannah M. Price, Tomoki Ozawa, Nigel R. Cooper +1
The Berry curvature is a geometrical property of an energy band which can act as a momentum space magnetic field in the effective Hamiltonian of a wide range of systems. We apply t…
Momentum-space Harper-Hofstadter model
Tomoki Ozawa, Hannah M. Price, Iacopo Carusotto
We show how the weakly trapped Harper-Hofstadter model can be mapped onto a Harper-Hofstadter model in momentum space. In this momentum-space model, the band dispersion plays the r…
A toolkit for semiclassical computations for strongly-driven molecules: "frustrated" ionization of H driven by elliptical laser fields
H. Price, C. Lazarou, A. Emmanouilidou
We study the formation of highly excited neutral atoms during the break-up of strongly-driven molecules. Past work on this significant phenomenon has shown that during the formatio…
Quantum Mechanics with a Momentum-Space Artificial Magnetic Field
Hannah M. Price, Tomoki Ozawa, Iacopo Carusotto
The Berry curvature is a geometrical property of an energy band which acts as a momentum space magnetic field in the effective Hamiltonian describing single-particle quantum dynami…
