Lanczos-like algorithm for the time-ordered exponential: The -inverse problem
Pierre-Louis Giscard, Stefano Pozza
The time-ordered exponential of a time-dependent matrix is defined as the function of that solves the first-order system of coupled linear different…
On the solutions of linear Volterra equations of the second kind with sum kernels
Pierre-Louis Giscard
We consider a linear Volterra integral equation of the second kind with a sum kernel and give the solution of the equation in terms of solutions of the s…
Exact dynamics of quantum systems driven by time-varying Hamiltonians: solution for the Bloch-Siegert Hamiltonian and applications to NMR
Pierre-Louis Giscard, Christian Bonhomme
Comprehending the dynamical behaviour of quantum systems driven by time-varying Hamiltonians is particularly difficult. Systems with as little as two energy levels are not yet full…
Computing Optimal Assignments in Linear Time for Approximate Graph Matching
Nils M. Kriege, Pierre-Louis Giscard, Franka Bause +1
Finding an optimal assignment between two sets of objects is a fundamental problem arising in many applications, including the matching of `bag-of-words' representations in natural…
