Spatial Discretization Error for Quantum Chemistry Simulation

Nonrelativistic quantum chemistry is based on the Schr\"odinger equation in continuous, unbounded space. Computational approaches on classical and quantum computers often truncate the spatial domain and introduce a finite-dimensional basis, reducing the continuum problem to a finite-dimensional one. There is therefore...

Splitting Analysis for Yukawa Potential

Splitting methods are among the most classical and fundamental tools for the simulation of quantum dynamics, and their importance has grown further with the rise of quantum computing. In this work, we analyze the Schr\"odinger equation with Yukawa potential, a physically relevant and widely used model potential. It may...
