Optical response of the supersolid polaron
Laurent H. A. Simons, Ralf Klemt, Tilman Pfau +2
The ground-state properties of the supersolid polaron consisting of a neutral impurity immersed in a dipolar supersolid have recently been studied. Here, the optical response of an…
Path-integral treatment of charged Bose polarons
Laurent H. A. Simons, Michiel Wouters, Jacques Tempere
The system of a charged impurity in an interacting Bose gas has gained significant attention due to the long-range ion-atom interactions and the study of transport properties. Here…
Polarons in supersolids: path-integral treatment of an impurity in a one-dimensional dipolar supersolid
Laurent H. A. Simons, Michiel Wouters, Jacques Tempere
The supersolid phase of a dipolar Bose-Einstein condensate has an intriguing excitation spectrum displaying a band structure. Here, the dressing of an impurity in a one-dimensional…
A path integral approach to closed-form option pricing formulas with applications to stochastic volatility and interest rate models
D. Lemmens, M. Wouters, J. Tempere +1
We present a path integral method to derive closed-form solutions for option prices in a stochastic volatility model. The method is explained in detail for the pricing of a plain v…
Feshbach resonances in a quasi-2D atomic gas
M. Wouters, J. Tempere, J. T. Devreese
Strongly confining an ultracold atomic gas in one direction to create a quasi-2D system alters the scattering properties of this gas. We investigate the effects of confinement on F…
