Speaker: Karsten Held, TU Vienna
Location: Mondi Seminar Room 2, Central Building
After a brief introduction to these methods, I will present some recent
highlights: the discovery of a new universality class of quantum critical exponents in the Hubbard model , the description of quantum criticality in the periodic Anderson model , and the discovery of new polaritons in strongly correlated electron systems, coined $\pi$-tons.
