Derivation of viscous correction terms for the isothermal quantum
... In the case of the isothermal quantum Euler equation, i.e. when we make ε = 0 in (26), it has been shown in [6] that when the initial data is irrotational, then the solution remains irrotational for all time. Unfortunately, it is not clear whether this property remains true for the quantum Navier-St ...

Macroscopic quantum effects based on Kerr nonlinearities

The thesis contains two projects, aiming at two reasons for the above problem. In the first project (Chapter 3 and 4), we show that the required resolution ...
