Bootstrapping Open Quantum Many-body Systems with Absorbing Phase Transitions
Minjae Cho, Colin Oscar Nancarrow, Petar Tadić +1
We demonstrate that combining the positivity of density matrices with steady-state conditions yields a systematic bootstrap method for studying open quantum many-body systems gover…

Precision study of the massive Schwinger model near quantum criticality
Erick Arguello Cruz, Grigory Tarnopolsky, Yuan Xin
We perform a numerical analysis of the massive Schwinger model in the presence of a background electric field. Using the Density Matrix Renormalization Group (DMRG) approach, we ef…

Coarse-grained Bootstrap of Quantum Many-body Systems
Minjae Cho, Colin Oscar Nancarrow, Petar Tadić +2
We present a new computational framework combining coarse-graining techniques with bootstrap methods to study quantum many-body systems. The method efficiently computes rigorous up…
