Multi-partite entangled states are many-body quantum states that cannot be written as a product state. As such, they possess a complicated yet fascinating structure of quantum correlations whose nature is hard to decipher. The idea behind this talk is to introduce a framework capable of advancing our understanding of such a structure of correlations, and relate it to known physical properties of many-body ground-states.
This is done by exploiting the Path-Integral picture of quantum Mechanics, by building particular suitable probes defined in terms of the geometric braiding of world-lines in Path-Integral Monte-Carlo configurations. The goal is developing new tools to study many-body correlations, and multi-partite entanglement of hardcore Bose-Hubbard models in a more complete way than the standard, scalar (bipartite) entanglement-estimators (e. g. entanglement entropies etc.).
Dr. Lingua obtained his Ph.D. in 2017 from Politecnico di Torino in Italy under the supervision of Prof. Vittorio Penna. He then joined the Department of Physics in Clark University as a postdoc, working with Prof. Barbara Capogrosso Sansone. In 2020, Dr. Lingua moved to Dartmouth college for his second postdoc job working with Prof. Lorenza Viola. His main research interest is on Quantum Monte Carlo simulations of strongly interacting bosonic systems and development of numerical methods for the study of entangled quantum states.
