Neural Networks and Value at Risk
Alexander Arimond, Damian Borth, Andreas Hoepner +2
Utilizing a generative regime switching framework, we perform Monte-Carlo simulations of asset returns for Value at Risk threshold estimation. Using equity markets and long term bo…
Equation of state and Kosterlitz-Thouless transition temperature in two-dimensional Fermi gases: An analytical approach
Michael Klawunn
We study Fermi gases in two dimensions at low temperatures with attractive interactions. Analytical results are derived for the equation of state and the Kosterlitz-Thouless transi…
Polar molecules in bilayers with high population imbalance
Michael Klawunn, Alessio Recati
We investigate a dilute Fermi gas of polar molecules confined into a bilayer setup with dipole moments polarized perpendicular to the layers. In particular, we consider the extreme…
Non-local state-swapping of polar molecules in bilayers
A. Pikovski, M. Klawunn, A. Recati +1
The observation of significant dipolar effects in gases of ultra-cold polar molecules typically demands a strong external electric field to polarize the molecules. We show that eve…
The Fermi-polaron in two dimensions: Importance of the two-body bound state
Michael Klawunn, Alessio Recati
We investigate a single impurity interacting with a free two-dimensional atomic Fermi gas. The interaction between the impurity and the gas is characterized by an arbitrary attract…
Local atom-number fluctuations in quantum gases at finite temperature
M. Klawunn, A. Recati, L. P. Pitaevskii +1
We investigate the number fluctuations in small cells of quantum gases pointing out important deviations from the thermodynamic limit fixed by the isothermal compressibility. Both…
