The covariance matrix spectrum of correlated charge insulators reveals hidden connections to Coupled Cluster, Matrix Product, and Rokhsar-Kivelson states
Izak Snyman, Serge Florens
Charge ordering induced by strong short-range repulsion in itinerant fermion systems typically follows a two-sites alternation pattern. However, the covariance matrix spectrum of t…

Direct detection of down-converted photons spontaneously produced at a single Josephson junction
Dorian Fraudet, Izak Snyman, Denis M. Basko +7
We study spontaneous photon decay into multiple photons triggered by strong non-linearities in a superconducting quantum simulator of the boundary sine-Gordon impurity model. Previ…

Analysis and Applications of the Generalised Dyson Mapping
I. Snyman
Generalised Dyson boson-fermion mappings are considered. These are techniques used in the analysis of the quantum many-body problem, and are instances of so-called boson expansion…
