scaling and IR/UV-mixing in Ising-nematic quantum critical metals
Bernhard Frank, Francesco Piazza
The instability of a Fermi surface against Ising nematic order destroys the quasiparticle character of the low-energy degrees of freedom. Therefore, observables exhibit deviations…
Quantum critical thermal transport in the unitary Fermi gas
Bernhard Frank, Wilhelm Zwerger, Tilman Enss
Strongly correlated systems are often associated with an underlying quantum critical point which governs their behavior in the finite temperature phase diagram. Their thermodynamic…
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…
