Strongly correlated electron systems host some of the most intriguing phenomena in condensed matter
physics, from unconventional superconductivity to quantum criticality and strange metallicity. But how
quantum are they, really? I will discuss how quantum information concepts, in particular the quantum

We propose to combine Bose-Einstein condensation in higher Bloch bands and a driven-dissipative cavity-BEC system into a hybrid light-matter platform. Specifically, the condensate is trapped in a bipartite $s$–$p_x$–$p_y$ lattice, with a tunable energy offset. This enables a controlled population transfer from the $s$-orbital to the nearly degenerate $p_x$ and $p_y$ orbitals. The system forms...
Over the past 30 years, tensor network techniques have been established as powerful tools in computational condensed matter physics. In one-dimensional quantum systems, one usually represents the many-body wave function as a matrix product state (MPS), a tensor network consisting of three-legged tensors, with individual tensors corresponding to the lattice sites in the system. This ansatz...
Entangled photon pair sources are essential resources for quantum technological applications. AlGaAs Bragg reflection waveguides are promising platform for such sources due to their high nonlinear coefficient, room temperature operation, and non-birefringent nature [1]. By using a type-II SPDC process, the down-converted photons are orthogonally polarized, and the generated photon pairs are...
We report on the electronic and topological properties of ZrTe₅ flakes synthesized via chemical vapor transport (CVT). Mechanically exfoliated ZrTe₅ flakes with nominal thicknesses ~100 nm are transferred onto pre-fabricated Pt contacts with 1-3-3-1 Hall bar geometries on SiO₂/Si sugbstrates. Using ac phase-locked low-/high-magnetotransport measurements, a distinct longitudinal resistance peak...
