Zero-point energy of tensor fluctuations on the MPS manifold
Sebastian Leontica, Andrew G. Green
This work presents a method for studying low-energy physics in highly correlated magnetic systems using the matrix product state (MPS) manifold. We adapt the spin-wave approach, wh…

Entanglement growth from squeezing on the MPS manifold
Sebastian Leontica, Andrew G. Green
Finding suitable characterizations of quantum chaos is a major challenge in many-body physics, with a central difficulty posed by the linearity of the Schrödinger equation. A possi…
