Iterative Projection-Based Embedding Scheme Combined with Variational Quantum Eigensolver
Hongseok Choi, Kyungmin Kim, Young Min Rhee
Quantum embedding methods offer a promising route to extend quantum chemical calculations to large multiscale systems by treating a chemically important subsystem at a high level o…
Minimization of disorder as a key design principle for natural sizes of light harvesting 2 complexes
Kwang Hyun Cho, Seogjoo J. Jang, Young Min Rhee
The light harvesting 2 (LH2) complex of purple bacteria has excellent energy conversion efficiency. Clarifying the design principle behind such efficiency at the atomistic level is…
Hybrid QPE-Ansatz Strategy for Reliable Excited-State Variational Quantum Deflation
Young Kyun Ahn, Young Min Rhee
We introduce a spin -component () conserving symmetry-preserving ansatz and a shallow quantum phase estimation (QPE) routine of spin (), and combine them into a…
Perspective of Fermi's golden rule and its generalizations in chemical physics
Seogjoo J. Jang, Goun Kim, Young Min Rhee
This perspective provides a succinct history of Fermi's golden rule (FGR), overview of its derivation, assumptions, and representative forms. Major applications of FGR, mostly in t…
Very-Large-Scale GPU-Accelerated Nuclear Gradient of Time-Dependent Density Functional Theory with Tamm-Dancoff Approximation and Range-Separated Hybrid Functionals
Inkoo Kim, Daun Jeong, Leah Weisburn +11
Modern graphics processing units (GPUs) provide an unprecedented level of computing power. In this study, we present a high-performance, multi-GPU implementation of the analytical…
