Sang-Wook Cheong

Sang-Wook Cheong 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 Sang-Wook Cheong rather than just read about it. In short: Sang-Wook Cheong (Korean: 정상욱) is an American materials scientist at Rutgers University. He has made ground-breaking contributions to the research field of enhanced physical functionalities in complex materials originating from collective correlations and collective phase transitions such as colossal magnetoresistive and colossal magnetoelectric effects in complex oxides.

Key takeaways

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

Reference excerpt

Sang-Wook Cheong (Korean: 정상욱) is an American materials scientist at Rutgers University. He has made ground-breaking contributions to the research field of enhanced physical functionalities in complex materials originating from collective correlations and collective phase transitions such as colossal magnetoresistive and colossal magnetoelectric effects in complex oxides. He has also made pivotal contributions to mesoscopic self-organization in solids, including the nanoscale charge stripe formation, mesoscopic electronic phase separation in mixed valent transition metal oxides, and the formation of topological vortex domains in multiferroics, which was found to be synergistically relevant to mathematics (graph theory) and cosmology.

Education Cheong graduated in mathematics from Seoul National University in 1982 and then studied physics in the University of California, Los Angeles, graduating from there in 1989.

Career From 1986 to 1989 Cheong worked at the Los Alamos National Laboratory before joining AT&T Bell Laboratories. He was appointed as a professor at Rutgers University in 1997 and founded the Rutgers Center for Emergent Materials (RCEM) in 2005. He is currently the director of RCEM, a Board of Governors Professor at Rutgers, and a Distinguished Professor at Postech, Korea. His work on complex oxides has been recognized through various prizes, including the 2007 Ho-am Prize, the KBS 2009 Global Korean Award, and the 2010 James C. McGroddy Prize for New Materials. He has published more than 600 scientific papers which have been cited more than 34,000 (six papers cited more than 1,000 times, and his h-index is 92). He was the 13th most cited physicist in the world in from 1993 to 2003.

Worked examples

Example 1 — a first encounter with Sang-Wook Cheong

Start with the simplest possible case. Write down what Sang-Wook Cheong 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 Sang-Wook Cheong 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 Sang-Wook Cheong 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 Sang-Wook Cheong

In research: Sang-Wook Cheong 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 Sang-Wook Cheong 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: Sang-Wook Cheong is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fellows of the American Physical Society, Living people, Los Alamos National Laboratory personnel, so understanding it makes those chapters shorter.
In everyday life: Look for Sang-Wook Cheong 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.
