About This Blog
This blog accompanies the research activities of the Multiscale Quantum Algorithms group. I created it as a space to reflect on the ideas, assumptions, and motivations that underlie my work and that of my group—topics that do not always fit naturally into research papers.
Much of my research lies at the intersection of mathematics, physics, chemistry, and computer science. While formal publications are essential for communicating technical results, they often leave little room for discussing why certain approaches are taken, how different modeling scales interact, or what broader implications algorithmic choices may have. This blog is meant to complement the scientific literature by addressing those questions more openly.
Motivation
Quantum molecular simulations rely on a layered stack of models and approximations. Over time, these layers can become implicit, especially as algorithms grow more complex and computationally efficient. I believe it is important to occasionally step back and examine the foundations of our methods—both mathematical and conceptual.
My motivation for this blog is therefore to:
- Make algorithmic and multiscale thinking explicit
- Discuss foundational aspects of electronic-structure theory and many-body methods
- Offer a measured perspective on newer developments, such as surrogate modeling or quantum computing, without hype
What to expect
Most posts will be short, essay-style pieces rather than tutorials or announcements. Likely topics include:
- Multiscale interpretations of quantum and many-body algorithms
- Mathematical foundations of electronic-structure methods, including DFT and GW–BSE
- Surrogate models and reduced representations in quantum chemistry
- Algorithmic perspectives on quantum computing for molecular systems
- Reflections on scientific software, reproducibility, and methodology
Occasionally, I will also write about broader topics: general issues in science, academic culture, or the role of computation and modeling in society. These posts will be more reflective in nature, but still grounded in experience as a researcher.
While most contributions will be written by me, other members of the group will occasionally contribute posts, offering their own perspectives on research, methods, or academic life.
Audience
This blog is written for researchers and students interested in quantum molecular science in a broad sense. Some posts may lean more toward theory or mathematics, others toward computational practice or reflection, but all are intended for readers who are comfortable engaging across disciplinary boundaries.
Looking ahead
Posts will appear irregularly, whenever there is something worth writing about. The goal is not frequency, but clarity and substance.
I hope this blog provides some insight into how I think about multiscale quantum algorithms, and perhaps encourages thoughtful discussion beyond the confines of formal publications.
