Correlated reaction coordinate motion produces non-additive rate enhancement for electron and energy transfer in multi-acceptor structures
Hanggai Nuomin, Feng-Feng Song, Peng Zhang +1
Molecular structures with multiple donor, bridge, or acceptor units can display quantum interference effects that influence electron and energy transfer (ET and EnT) rates. Recent…

Superfluid dome in the spatially modulated two-dimensional XY model
Feng-Feng Song, Aditya Chugh, Hanggai Nuomin +2
In strongly correlated electron systems, superconductivity and charge density waves often coexist in close proximity, suggesting a deeper relationship between these competing phase…

Emergent Intermediate Phase in the - XY model from Tensor Network Approaches
Feng-Feng Song, Hanggai Nuomin, Naoki Kawashima
We investigate the finite-temperature phase diagram of the classical - XY model on a square lattice using a tensor network approach designed for frustrated spin systems.…
