- Abstract: Deformed correlated Gaussian basis functions are introduced and their matrix
elements are calculated. These basis functions can be used to solve problems
with nonspherical potentials. One example of such potential is the dipole
self-interaction term in the Pauli-Fierz Hamiltonian. Examples are presented
showing the accuracy and necessity of deformed Gaussian basis functions to
accurately solve light-matter coupled systems in cavity QED.

Unavoidable coupling of quantum systems to external degrees of freedom leads to dissipative (non-unitary) dynamics.
We introduce a method to deal with these systems based on the calculation of (dissipative) lattice Green's function.
We illustrate the power of this method with several examples of driven-dissipative bosonic chains of increasing complexity.
