Paul Brehmer

Currently M. Sc. student at RWTH Aachen University, Germany doing theoretical condensed matter physics and soon-to-be PhD student at University of Vienna, Austria, continuing with quantum information approaches to many-body systems. Outside of physics, I like to spend my time doing music-related things.

Surrogatising quantum spin systems using reduced basis methods

07/27/2023, 6:30 PM ‚ÄĒ 7:00 PM UTC

Quantum spin systems are a central topic in condensed matter physics. Their simplicity enables systematic study of the quantum properties, which has notable applications in, e.g., quantum computing. With ReducedBasis.jl we provide a Julia package, which uses reduced-basis methods to accelerate the modeling of parametrised eigenvalue problems, such as typical for quantum spin Hamiltonians. The package integrates with ITensors enabling a treatment using state-of-the-art tensor network methods.
