11:15 | Lucas Hackl (MPQ Garching) | Low energy spectra from variational tangent planes |
|---|
| Variational methods are extensively used to study properties of ground states and low excited states. By focusing on a suitable sub-manifold of states, we can overcome the exponential growth of the Hilbert space with the system size. In this talk, I will introduce a geometric framework to approximate the low lying energy spectrum by studying the linearized Hamiltonian flow on the tangent plane at the ground state. The spectrum is then given by the eigenvalues of the covariant derivative on the variational manifold. Using the paradigmatic Bose-Hubbard model as an example, I will discuss advantages compared to methods based on directly diagonalizing the Hamiltonian restricted to the tangent plane.
