Subtle Spin: A Novel Study of Quantum Material Proves Theoretical Predictions
Researchers have discovered a hard-to-observe type of spin in a quantum mechanical system. In physics, a quantum mechanical system is a set of components that interact at the quantum scale. This is the realm of atoms and subatomic particles such as those defined in the Standard Model of Particle Physics. Spins are magnetic particles in… Continue Reading →

Hydrodynamics in a Quantum Spin Chain
Long wavelength spin fluctuations in a quantum spin chain correspond to superdiffusive classical hydrodynamics belonging to the Kardar-Parisi-Zhang (KPZ) universality class. Continue Reading →
