Physics colloquium-“Quantum Magnetism”
January 28 @ 4:00 pm
Colorado State University, Department of Physics
Abstract: When interactions are strong between spins on a lattice, complex many-body collective effects can occur. With low spin values like S=1/2, quantum mechanical effects can play a qualitative and quantitative role in determining these collective behaviors. Entanglement and strong quantum fluctuations can completely change the nature of the magnetic material, making such states interesting platforms for studying quantum many-body effects, both in and out of equilibrium. Understanding this is essential for building the next “quantum” technologies. Therefore, quantum phases of matter are highly sought after in real materials. I will give a broad view of the subject of quantum magnetism, including Quantum Dimer Magnets and Quantum Spin Liquids, and touch on how we are starting to explore their non-equilibrium properties.
