Effects of Donor-Acceptor Quantum Coherence and Non-Markovian Bath on the Distance Dependence of Resonance Energy Transfer
Seogjoo J. Jang
Accurate information on the distance dependence of resonance energy transfer (RET) is crucial for its utilization as a spectroscopic ruler \re{of} nanometer scale distances. In thi…
Multistep quantum master equation theory for response functions in four wave mixing electronic spectroscopy of multichromophoric macromolecules
Seogjoo J. Jang
This work provides an alternative derivation of third order response functions in four wave mixing spectroscopy of multichromophoric macromolecular systems considering only single…
Modified Fermi's golden rule rate expressions
Seogjoo J. Jang, Young Min Rhee
Fermi's golden rule (FGR) serves as the basis for many expressions of spectroscopic observables and quantum transition rates. The utility of FGR has been demonstrated through decad…
Partially polaron-transformed quantum master equation for exciton and charge transport dynamics
Seogjoo J. Jang
Polaron-transformed quantum master equation (PQME) offers a unified framework to describe the dynamics of quantum systems in both limits of weak and strong couplings to environment…
Fundamental trade-off between the speed of light and the Fano factor of photon current in three-level lambda systems
Davinder Singh, Seogjoo J. Jang, Changbong Hyeon
Electromagnetically induced slow-light medium is a promising system for quantum memory devices, but controlling its noise level remains a major challenge to overcome. This work con…
A simple generalization of the energy gap law for nonradiative processes
Seogjoo J. Jang
For more than 50 years, an elegant energy gap (EG) law developed by Englman and Jortner [Mol. Phys. {\bf 18}, 145 (1970)] has served as a key theory to understand and model nearly…
Non-uniqueness of quantum transition state theory and general dividing surfaces in the path integral space
Seogjoo Jang, Gregory A. Voth
Despite the fact that quantum mechanical principles do not allow the establishment of an exact quantum analogue of the classical transition state theory (TST), the development of a…
Generalized quantum Fokker-Planck equation for photoinduced nonequilibrium processes with positive definiteness condition
Seogjoo Jang
This work provides a detailed derivation of a generalized quantum Fokker-Planck equation (GQFPE) appropriate for photo-induced quantum dynamical processes. The path integral method…
