Statistics of matrix elements of local operators in integrable models
F. H. L. Essler, A. J. J. M. de Klerk
We study the statistics of matrix elements of local operators in the basis of energy eigenstates in a paradigmatic integrable many-particle quantum theory, the Lieb-Liniger model o…
Improved Hilbert space exploration algorithms for finite temperature calculations
A. J. J. M. de Klerk, J. -S. Caux
Computing correlation functions in strongly-interacting quantum systems is one of the most important challenges of modern condensed matter theory, due to their importance in the de…
On computing non-equilibrium dynamics following a quench
Neil J. Robinson, Albertus J. J. M. de Klerk, Jean-Sébastien Caux
Computing the non-equilibrium dynamics that follows a quantum quench is difficult, even in exactly solvable models. Results are often predicated on the ability to compute overlaps…
Knotted optical vortices in exact solutions to Maxwell's equations
Albertus Johannes Jacobus Maria de Klerk, Roland Ivo van der Veen, Jan Willem Dalhuisen +1
We construct a family of exact solutions to Maxwell's equations in which the points of zero intensity form knotted lines topologically equivalent to a given but arbitrary algebraic…
