Quasiparticles do the twist

Posted on July 19, 2025 by

Physics often involves hidden surprises in how matter behaves at the smallest scales. A fundamental property in physics is angular momentum, which describes how things spin or rotate, from planets all the way down to particles. Angular momentum is involved … Continue reading →

The imperfection of strontium titanate

Posted on November 29, 2019 by

When you squeeze some crystals, you distort their lattice of atoms just enough to separate a pair of charged particles and that in turn gives rise to a voltage. Such materials are called piezoelectric crystals. Not all crystals are piezoelectric … Continue reading →
