Fast logarithmic Fourier-Laplace transform of nonintegrable functions
Johannes Lang, Bernhard Frank
We present an efficient and very flexible numerical fast Fourier-Laplace transform, that extends the logarithmic Fourier transform (LFT) introduced by Haines and Jones [Geophys. J.…
Dynamical Quantum Phase Transitions: A Geometric Picture
Johannes Lang, Bernhard Frank, Jad C. Halimeh
The Loschmidt echo (LE) is a purely quantum-mechanical quantity whose determination for large quantum many-body systems requires an exceptionally precise knowledge of all eigenstat…
Universal phase diagram and scaling functions of imbalanced Fermi gases
Bernhard Frank, Johannes Lang, Wilhelm Zwerger
We discuss the phase diagram and the universal scaling functions of attractive Fermi gases at finite imbalance. The existence of a quantum multicritical point for the unitary gas a…
