Quantum circuit algorithm for topological invariants of second order topological many-body quantum magnets
Sebastián DomÃnguez-Calderón, Marcel Niedermeier, Jose L. Lado +1
The paper presents a quantum circuit algorithm that computes many‑body topological invariants for second‑order topological quantum magnets using adiabatic evolution on a quantum co…
Self-consistent tensor network method for correlated super-moiré matter beyond one billion sites
Yitao Sun, Marcel Niedermeier, Tiago V. C. Antão +2
Moiré and super-moiré materials provide exceptional platforms to engineer exotic correlated quantum matter. The vast number of sites required to model moiré systems in real spac…
Solving the Gross-Pitaevskii equation on multiple different scales using the quantics tensor train representation
Marcel Niedermeier, Adrien Moulinas, Thibaud Louvet +2
Solving partial differential equations of highly featured problems represents a formidable challenge, where reaching high precision across multiple length scales can require a proh…
Correlated states in super-moiré materials with a kernel polynomial quantics tensor cross interpolation algorithm
Adolfo O. Fumega, Marcel Niedermeier, Jose L. Lado
Super-moiré materials represent a novel playground to engineer states of matter beyond the possibilities of conventional moiré materials. However, from the computational point of…
Quantum computing topological invariants of two-dimensional quantum matter
Marcel Niedermeier, Marc Nairn, Christian Flindt +1
Quantum algorithms provide a potential strategy for solving computational problems that are intractable by classical means. Computing the topological invariants of topological matt…
