abstract
This work presents an analytic description of the coherent excitation of a two-state quantum system by an external field with a Lorentzian temporal shape and a constant frequency. An exact analytical solution for the differential equation of the model is derived in terms of Confluent Heun functions. Also a very accurate analytic approximation to the transition probability is derived by using the Dykhne-Davis-Pechukas approach. This approximation provides analytic expressions for the frequency and amplitude of the probability oscillations.

DRAG-Compatible Leakage Suppression in Landau--Zener Control via Isoprobability Twins
Pulse pairs generated from the same Stückelberg function produce identical post-pulse transition probabilities, demonstrated on IBM hardware, but the abstract's DRAG leakage reduction claim is absent from the body.
