In this repository, we open-source sample codes that were developed by me to simulate the simulate the spatial energy distribution as a function of temperature in equilibrium quantum systems: technical report

Below we depict the spatial energy distribution as a function of temperature of a 3-qubit system maintained in thermal equilibrium, characterized by two "local marginals" (localized energy on 2-qubit subsystems). The solid lines are theoretical expectations, while the dashed lines represent a numerical approximation of the same by evolving our theory (an Initial Value Problem) using the generalized RK4 algorithm.
