Full distribution of the superfluid fraction and extreme value statistics in a one dimensional disordered Bose gas
M. Albert, C. A. Müller
The full statistical distribution of the superfluid fraction characterizing one-dimensional Bose gases in random potentials is discussed. Rare configurations with extreme fluctuati…
Weak localization of magnons in chiral magnets
Martin Evers, Cord A. Müller, Ulrich Nowak
We report on the impact of the Dzyaloshinskii-Moriya interaction on the coherent backscattering of spin waves in a disordered magnetic material. This interaction breaks the inversi…
Leading gradient correction to the kinetic energy for two-dimensional fermion gases
Martin-Isbjörn Trappe, Yink Loong Len, Hui Khoon Ng +2
Density functional theory (DFT) is notorious for the absence of gradient corrections to the two-dimensional (2D) Thomas-Fermi kinetic-energy functional; it is widely accepted that…
Spin-wave localization in disordered magnets
Martin Evers, Cord A. Müller, Ulrich Nowak
The effect of disorder on magnonic transport in low-dimensional magnetic materials is studied in the framework of a classical spin model. Numerical investigations give insight into…
Anderson localization of Bogoliubov excitations on quasi-1D strips
Christopher Gaul, Pierre Lugan, Cord A. Müller
Anderson localization of Bogoliubov excitations is studied for disordered lattice Bose gases in planar quasi-one-dimensional geometries. The inverse localization length is computed…
Echo spectroscopy of Anderson localization
T. Micklitz, C. A. Müller, A. Altland
We propose a conceptually new framework to study the onset of Anderson localization in disordered systems. The idea is to expose waves propagating in a random scattering environmen…
