Spin liquid and Deconfined Criticality in a Kagome Lattice Bose-Hubbard Model Speaker(s): Roger Melko
Abstract: We present large-scale quantum Monte Carlo simulations on a sign-problem free Bose-Hubbard model on the kagome lattice. This model supports a quantum Z2 spin liquid phase with fractional excitations and topological order, which can be characterized definitively through calculation of the topological... read more

Computing Entanglement in Simulations of Quantum Condensed Matter Speaker(s): Roger Melko
Abstract: Condensed matter theorists have recently begun exploiting the properties of entanglement as a resource for studying quantum materials. At the forefront of current efforts is the question of how the entanglement of two subregions in a quantum many-body groundstate scales with the subregion size. The ... read more

Computing Unconventional Quantum Phase Transitions Speaker(s): Roger Melko
Abstract: Calculating universal properties of quantum phase transitions in microscopic Hamiltonians is a challenging task, made possible through large-scale numerical simulations coupled with finite-size scaling analyses. The continuing advancement of quantum Monte Carlo technologies, together with modern hig... read more
