Exciton Energy Transfer in Conjugated Polymers via a Three-Level Donor-Acceptor Model
Hyeonseok Yang
We investigate intra-chain exciton energy transfer (EET) in a conjugated polymer using a reduced three-level donor-acceptor model that separates vertical excitations from vibration…
Geometric Phases of a Driven Qubit: Comparing Berry and Uhlmann Holonomies
Hyeonseok Yang, Changsuk Noh
The Berry phase arises naturally from the adiabatic dynamics of a pure quantum state, whereas the Uhlmann phase is usually formulated kinematically for a prescribed path of mixed s…
Geometric phase of open paths and a geodesic-selection rule at a level degeneracy
Hyeonseok Yang, Changsuk Noh
When the control field of a qubit, a polarization state, or a spin- system is swept through a level degeneracy, its direction traces an open curve on the Bloch sphere who…
Quantum Hierarchical Fokker-Planck Equations with U(1) Gauge Fields (U(1)-QHFPE): A Computational Framework for Aharonov-Bohm Effects
Shoki Koyanagi, Hyeonseok Yang, Yoshitaka Tanimura
We introduce U(1)-QHFPE, a non-Markovian and non-perturbative open quantum dynamics software package for solving quantum Fokker-Planck equations incorporating gauge fields within t…
