Time-dependent Hamiltonian Simulation of Highly Oscillatory Dynamics and Superconvergence for Schrödinger Equation
Dong An, Di Fang, Lin Lin
We propose a simple quantum algorithm for simulating highly oscillatory quantum dynamics, which does not require complicated quantum control logic for handling time-ordering operat…

Observable Error Bounds of the Time-splitting Scheme for Quantum-Classical Molecular Dynamics
Di Fang, Albert Tres
Quantum-classical molecular dynamics, as a partial classical limit of the full quantum Schrödinger equation, is a widely used framework for quantum molecular dynamics. The underlyi…

Parallel transport dynamics for mixed quantum states with applications to time-dependent density functional theory
Dong An, Di Fang, Lin Lin
Direct simulation of the von Neumann dynamics for a general (pure or mixed) quantum state can often be expensive. One prominent example is the real-time time-dependent density func…
