Minimal Effective Gibbs Ansatz (MEGA): A simple protocol for extracting an accurate thermal representation for quantum simulation
Jeffrey Cohn, Khadijeh Sona Najafi, Forest Yang +2
Quantum Gibbs state sampling algorithms generally suffer from either scaling exponentially with system size or requiring specific knowledge of spectral properties \textit{a priori}…

Area law and universality in the statistics of subsystem energy
Khadijeh Najafi, M. A. Rajabpour
We introduce Rényi entropy of a subsystem energy as a natural quantity which closely mimics the behavior of the entanglement entropy and can be defined for all the quantum many bod…

Light-cone velocities after a global quench in a non-interacting model
Khadijeh Najafi, M. A. Rajabpour, J. Viti
We study the light-cone velocity for global quenches in the non-interacting XY chain starting from a class of initial states that are eigenstates of the local -component of the…
