How much frustration is enough? A wide range of systems of many particles including the high temperature superconductors, ultracold gases and many low dimensional quantum systems exhibit exotic phase transitions at low very low temperatures from a localized insulating state to a delocalized conducting state. It is believed that many of these transitions are driven by quantum fluctuations. The two main effects which drive these transitions are strong local interactions which is impeding the motion of the particle and the energy gain by magnetic ordering, which leads to the question: Are the particles more localized or more magnetically ordered? The tendency to magnetic order can be suppressed experimentally by geometric frustration leading to the possibility of exotic magnetic states like spin liquids. I will present our results from simulations using modern refined modern computational tools. |
