Exact local correlations in kicked chains at light cone edges

Boris Gutkin, Petr Braun, Maram Akila +2

We show that local correlators in a wide class of kicked chains can be calculated exactly at light cone edges. Extending previous works on dual-unitary systems, the correlators bet…

Hilbert space average of transition probabilities

Nico Hahn, Thomas Guhr, Daniel Waltner

The typicality approach and the Hilbert space averaging method as its technical manifestation are important concepts of quantum statistical mechanics. Extensively used for expectat…

Local correlations in dual-unitary kicked chains

Boris Gutkin, Petr Braun, Maram Akila +2

We show that for dual-unitary kicked chains, built upon a pair of complex Hadamard matrices, correlators of strictly local, traceless operators vanish identically for sufficiently…

Towards a semiclassical understanding of chaotic single- and many-particle quantum dynamics at post-Heisenberg time scales

Daniel Waltner, Klaus Richter

Despite considerable progress during the last decades in devising a semiclassical theory for classically chaotic quantum systems a quantitative semiclassical understanding of their…

Transition from Quantum Chaos to Localization in Spin Chains

Petr Braun, Daniel Waltner, Maram Akila +2

Recent years have seen an increasing interest in quantum chaos and related aspects of spatially extended systems, such as spin chains. However, the results are strongly system depe…

New approach to periodic orbit theory of spectral correlations

Petr Braun, Daniel Waltner

The existing periodic orbit theory of spectral correlations for classically chaotic systems relies on the Riemann-Siegel-like representation of the spectral determinants which is s…
