Olaf Hohm

Olaf Hohm is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Olaf Hohm rather than just read about it. In short: Olaf Hohm is a German theoretical physicist and professor at Humboldt University of Berlin. He has worked on massive gravity, double field theory, exceptional field theory and applications of L ∞ {\displaystyle L_{\infty }} -algebras in field theory.

Key takeaways

  • Olaf Hohm belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Olaf Hohm to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Olaf Hohm from memory before moving on to harder problems.

Reference excerpt

Olaf Hohm is a German theoretical physicist and professor at Humboldt University of Berlin. He has worked on massive gravity, double field theory, exceptional field theory and applications of L ∞ {\displaystyle L_{\infty }} -algebras in field theory.

Education Hohm earned his PhD from the University of Hamburg in 2006, where his advisor was Henning Samtleben.

Career Following his PhD, Hohm conducted research at Utrecht University, University of Groningen, and at the Massachusetts Institute of Technology. In 2009, together with Eric Bergshoeff and Paul Townsend, he developed a consistent non-linear theory of massive gravity in 2+1 dimensions, called "New Massive Gravity", extending the linear theory of Fierz and Pauli from 1939. In 2010, together with Chris Hull and Barton Zwiebach, he co-developed double field theory. From 2011 to 2013, Hohm served as Akademischer Rat at LMU Munich, after which he was awarded a Heisenberg Fellowship and returned to work at MIT and the Simons Center for Geometry and Physics. In 2013, he and Samtleben formulated exceptional field theory. In 2018, he received an ERC Consolidator Grant and joined Humboldt University of Berlin, where he became a professor in 2022.

Worked examples

Example 1 — a first encounter with Olaf Hohm

Start with the simplest possible case. Write down what Olaf Hohm claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Olaf Hohm before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Olaf Hohm ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Olaf Hohm

In research
Olaf Hohm appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Olaf Hohm in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Olaf Hohm is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century German physicists, Academic staff of the Humboldt University of Berlin, German physicist stubs, so understanding it makes those chapters shorter.
In everyday life
Look for Olaf Hohm outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Olaf Hohm in simple terms?

Olaf Hohm is a German theoretical physicist and professor at Humboldt University of Berlin. He has worked on massive gravity, double field theory, exceptional field theory and applications of L ∞ {\displaystyle L_{\infty }} -algebras in field theory.

Why does Olaf Hohm matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Olaf Hohm?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
