  We investigate the phenomenon of Bottomonium melting in a thermal quark-gluon
plasma using three-dimensional stochastic simulations based on the concept of
open-quantum systems. In this non-relativistic framework, introduced in
[Phys.Rev. D85 (2012) 105011], which makes close contact to the potentials
derived in effective field theory, the $b\bar{b}$ system evolves unitarily
under the incessant kicks by the constituents of the surrounding heat bath. In
particular thermal fluctuations and the presence of a complex potential in the
EFT are naturally related. An intricate interplay between state mixing and
thermal excitations emerges as we show how non-thermal initial conditions of
Bottomonium states evolve over time. We emphasize that the dynamics of these
states gives us access to information beyond what is encoded in the thermal
Bottomonium spectral functions. Assumptions underlying our approach and their
limitations, as well as the refinements necessary to connect to experimental
measurements under more realistic conditions are discussed.
