24.11.2023: Talk by Yueshui Zhang: "Continuous Matrix Product Operator approach to finite temperature quantum states"
24.11.2023 at 09:00 - 24.11.2023 at 10:00
In this talk, I will present a Continuous Matrix Product Operator (cMPO) method for studying 1D and quasi-1D quantum lattice models at finite temperature. It provides direct access to thermodynamic quantities as well as local correlation functions. The nice feature of this method is that it is free of Trotter errors, works directly in the thermodynamic limit, and treats short-range and long-range interactions on equal footing. I will show benchmark results obtained by applying the cMPO method to some paradigmatic models. I will also discuss our recent progress on i) understanding the operator structure of cMPO and ii) the construction of crosscap states which encode universal conformal data.
