The Weyl calculus is a means of constructing functions of a system of hermitian operators which do not necessarily commute with each other. This note gives a new proof of a formula, due to E. Nelson, ...

In this paper, a generalized preconditioned Hermitian and skew-Hermitian splitting (GPHSS) iteration method for a non-Hermitian positive-definite matrix is studied, which covers standard Hermitian and ...

Simulation of non-Hermitian quantum mechanics using a quantum computer goes beyond centuries old conventions. Aalto researchers have used an IBM quantum computer to explore an overlooked area of ...

Many of our academics speak to the media as experts in their field of research. If you are a journalist, please contact the University’s Media and PR Team: Random Matrix Theory, Quantum Chaos and ...
