Emergent magnetostatics in frustrated magnets
Magnetic systems can encounter "frustration" when they are subject to competing interactions that cannot be simultaneously satisfied. Typically, the consequences include a large degeneracy of ground states and a suppression of thermal ordering. Even more fascinating, the low temperature physics of some of these systems can be captured in terms of emergent magnetostatics, or a so- called Coulomb phase with characteristic power-law correlations. Within this project, you can see how this happens in a tractable, classical spin model amenable to both analytical and numerical calculations that will reveal these emergent phenomena.

Entanglement in quantum many-body systems
Within this project you will investigate how ground states of interacting quantum many-body systems can be characterized in terms of entanglement. One quantitative measure of the latter comes in the form of the so-called entanglement entropy, which can be accessed via the reduced density matrix of an embedded subsystem. Following heuristic arguments you can derive bounds on this entanglement entropy, so-called area laws. With the help of numerical simulations you can then investigate the validity of these area laws for a set of tractable quantum models.
