Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the key property?The induced current is non-dissipative and topologically protected
2. What is the key researchers/institutions?Brookhaven National Laboratory, Stony Brook University, CERN (ALICE), STAR Collaboration (RHIC)
3. Why do left‑handed and right‑handed particles matter?Left‑handed and right‑handed particles have their spin pointing in different directions relative to their motion. If one type is more common, the magnetic field pushes them together to make a current.
4. How was the Chiral Magnetic Effect first seen in experiments?In 2014 scientists observed it in a crystal called ZrTe5. Later, experiments at Brookhaven and CERN saw it in the hot soup of particles from big collisions.

Chirality Imbalance: A state where there are unequal numbers of left-handed and right-handed chiral fermions in a system.
Topological Protection: A property that makes a phenomenon stable and resistant to disruption due to its fundamental mathematical structure.
Quantum Field Theory: A theoretical framework that combines quantum mechanics and special relativity to describe fundamental particles and forces.
Dirac Semimetal: A type of material exhibiting unique electronic properties where electrons behave like relativistic particles.
