Research interests:
My research focuses on the study of interacting quantum fields on curved spacetime backgrounds beyond the perturbative level, using variational numerical methods based on tensor network states. In the tensor network formalism the many-body wavefunction is encoded in terms of entanglement across virtual bonds, allowing us to directly study the entanglement spectrum. For one dimensional systems, the matrix product states (MPS) ansatz provides an efficient parametrization for the low energy states in the many-body Hilbert space.
In my PhD I would like to extend these techniques to (1+1)-dimensional toy models on black hole and cosmological spacetimes. This is mostly unexplored territory and beyond reach of alternative techniques such as Monte Carlo sampling. This approach could lead to ab-initio non-perturbative simulations of intriguing phenomena like the production of Hawking radiation and cosmic density perturbations from the vacuum.

Research:
I am interested in strongly correlated quantum many body systems and exotic phenomena in quantum condensed matter physics. My research focusses on studying these systems using the formalism of tensor networks, which offer a faithful description of low-energy quantum many body states, as motivated by the area law scaling of entanglement entropy. On the one hand, tensor network states enable accurate ab-initio simulations of the low-energy properties of strongly interacting Hamiltonians, while on the other they allow us to tackle general questions from the wave function point of view, irrespective of the details of any Hamiltonian or Lagrangian. Tensor network states also provide an interesting new perspective to holography and quantum gravity.
