Hi everybody, We will meet as usual at 4pm. Today’s talk is by Akshat Kumar from Sandia National Labs, Livermore, CA, USA on "model reduction for quantum dynamics: symmetries and invariant subspaces”, see below. see you there, Volkher abstract: We investigate methods for identifying reduced-order models of the dynamics generated by parameterized quantum Hamiltonians. In particular, we develop methods to characterize, identify and exploit invariant subspaces defined by a finite-dimensional Hamiltonian model and initial state. Further, by exploiting properties of the generalized Pauli group we provide some more efficient methods for dynamics generated by certain spin Hamiltonians. ******************************* Volkher Scholz ETH Zurich Institute for Theoretical Physics HIT K31.4 Wolfgang-Pauli-Strasse 27 8093 Zurich, Switzerland
