Modular Hamiltonians for future-perturbed states
Xiaole Jiang, Daniel Kabat, Aakash Marthandan +1
We develop a perturbative understanding of the modular Hamiltonian for a 2D CFT, divided into left and right half-spaces, with a weak local perturbation inserted in the future wedg…

Entanglement groups for mixed states
Xiaole Jiang, Daniel Kabat, Gilad Lifschytz +1
We extend an operational characterization of entanglement in terms of stabilizer groups from pure states to mixed states. For a density matrix , a stabilizer is a factoriz…
