Sven Köppel: Research

I am a theoretical physicist with a background in applied mathematics, mathematical physics and computer science. My current research focus is on exotic computing, such as analog, quantum and neuromorphic computers.

In the past, I studied advanced numerical methods for partial differential equations. Until 2019, I worked on exascale methods for solving hyperbolic equations within the European ExaHyPE project.

I did my PhD in physics about numerical and quantum general relativity in 2019. A major research interest during my studies was exotic high energy physics and quantum field theory.

Analog computing

Analog computing is a rediscovered branch of science which was beaten by digital (i.e. algorithmic/numeric) computing in the 1980s. In the dawn of Moore's law, this branch of classical computing percieves a revival. Based on the experience of programmable hardware (FPGAs), it is tangible to build large analog circuits to solve differential equations in a time- and energy-efficient way beyond digital computing. I am part of a German-based team which tries to develop a prototypical analog computer on a chip within the next few years.

There is a rich scientific landscape waiting to be discovered all around this exotic branch of computer science and intersection between electrical engineering, computational science and applied mathematics. Many concepts of numerical mathematics can be transfered and connections to other contemporary attempts to computing, namely quantum computing and artificial intelligence, are all along the way. It is an exciting time where analog circuits can make a radical difference in the computational accessibility of the largest problems in the world.

Reference material about analog computing

Note: I am conducting research on analog computing since half a year and a couple of publications are in the pipeline. In the meantime, see for instance these publications:

(Note to myself: We have more then 300 papers compiled on analog computing in all kind of scientific branches and will put a literature database online soon)

My Publications

You find my papers at Inspire-HEP, NASA-ADS, DBLP ArXiV. In the past, I wrote a couple of outreach press/blog posts.

You can read my PhD thesis about high-order methods in fully general-relativistic hydrodynamics and magnetohydrodynamics and my Master thesis about ultraviolet improved black holes.

Trivia

The mathematics genealogy project has an entry about me. I have a ResearchGate profile and my ORCID is 0000-0003-2303-7765.

There are a couple of other Sven Köppel around, which are not me. These are for instance @testpilot76, this instagrammer or that person in Hamburg.

I am on the web since 2000. I have a couple of older websites, for instance my old website at Goethe University.
