Exact S-matrices for higher dimensional representations of generalized Landau-Zener Hamiltonians
S. Malikis, V. Cheianov
We explore integrable Landau-Zener-type Hamiltonians through the framework of Lie algebraic structures. By reformulating the classic two-level Landau-Zener model as a Lax equation,…

Integrability and chaos in the quantum brachistochrone problem
S. Malikis, V. Cheianov
The quantum brachistochrone problem addresses the fundamental challenge of achieving the quantum speed limit in applications aiming to realize a given unitary operation in a quantu…
