Exact ground states of quantum many-body systems under confinement

A del Campo - Physical Review Research, 2020 - APS
Knowledge of the ground state of a homogeneous quantum many-body system can be used
to find the exact ground state of a dual inhomogeneous system with a confining potential …

Local Hamiltonians for one-dimensional critical models

Conformal field theory has turned out to be a powerful tool to derive interesting lattice
models with analytical ground states. Here, we investigate a class of critical, one …
