Explore a 29-minute lecture on advanced quantum dynamics approximation techniques presented by Berge Englert from the Centre for Quantum Technologies & MajuLab at the National University of Singapore. Delve into a novel five-factor Suzuki-Trotter type approximation for the unitary evolution operator in nonrelativistic quantum dynamics, offering fifth-order accuracy with fewer factors than the standard method. Examine the successful benchmarking of this approximation and its application in a comprehensive numerical study of a Stern-Gerlach interferometer with realistic magnetic fields. Learn about spin-dependent forces, magnetic field interactions, and the concept of reversibility in quantum systems. Gain insights into the benchmarking process and its importance in validating new approximation techniques. Reference key publications for further study, including works from New Journal of Physics and Symmetry.
