John L. Sarrao

John L. Sarrao 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 John L. Sarrao rather than just read about it. In short: John Louis Sarrao (born February 1, 1967) is an American physicist. He was the deputy director for science, technology, and engineering at Los Alamos National Laboratory.

Key takeaways

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

Reference excerpt

John Louis Sarrao (born February 1, 1967) is an American physicist. He was the deputy director for science, technology, and engineering at Los Alamos National Laboratory. As of 2 October 2023, he became the sixth director of SLAC National Accelerator Laboratory

Education In 1993, Sarrao received his PhD in physics from the University of California Los Angeles following a M.S. in physics from UCLA in 1991 and a B.S. in physics from Stanford University in 1989. He is a Fellow of the American Association for the Advancement of Science; the American Physical Society; and the Los Alamos National Laboratory.

Career He is the principal architect of LANL's Dynamic Mesoscale Material Science Capability (DMMSC). He is a board member of the Technology Research Collaborative (TRC). Sarrao's research includes quantum computing. On June 7, 2018, Sarrao presented Congressional Testimony for the House Science, Space & Technology Committee Subcommittee on Energy on topics including electric grid research and big data.

Honors and awards In 2013, he was awarded the United States Department of Energy's Ernest Orlando Lawrence Award for his research in Condensed Matter and Materials Science: "For the discovery and study of new materials, especially those based on Plutonium, advancing understanding of unconventional magnetic and superconducting states in strongly correlated f-electron condensed matter systems." He was honored for his discovery and study of new materials, especially those based on Plutonium, that advance understanding of novel magnetic and superconducting states in strongly correlated f-electron condensed matter systems. The complexity of strongly correlated materials, resulting from coupling among charge, spin, and lattice degrees-of-freedom, allows the emergence of new states and new phenomena, helping promote the development of useful and novel functional materials.

Worked examples

Example 1 — a first encounter with John L. Sarrao

Start with the simplest possible case. Write down what John L. Sarrao 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 John L. Sarrao 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 John L. Sarrao 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 John L. Sarrao

In research: John L. Sarrao 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 John L. Sarrao 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: John L. Sarrao is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1967 births, 20th-century American physicists, 21st-century American physicists, so understanding it makes those chapters shorter.
In everyday life: Look for John L. Sarrao 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.
