In condensed matter systems, such as electrons in solids and liquid helium, competitions and/or collaborations of quantum nature and interparticle interactions lead to various interesting phenomena, including superfluidity, superconductivity, quantum phase transitions, and many-body localization. We develop theoretical methods describing quantum many-body systems, aiming to discover novel quantum many-body effects.
