Revealing symmetries in quantum computing for many-body systems
Robert van Leeuwen
We develop a method to deduce the symmetry properties of many-body Hamiltonians when they are prepared in Jordan-Wigner form for evaluation on quantum computers. Symmetries, such a…

Geometrical Perspective on Spin-Lattice Density-Functional Theory
Markus Penz, Robert van Leeuwen
A recently developed viewpoint on the fundamentals of density-functional theory for finite interacting spin-lattice systems that centers around the notion of degeneracy regions is…

From S-matrix theory to strings: Scattering data and the commitment to non-arbitrariness
Robert van Leeuwen
The early history of string theory is marked by a shift from strong interaction physics to quantum gravity. The first string models and associated theoretical framework were formul…
