Macroscopic Zero-Mode Manifold Isolated by Quantum Chaos
Cheryne Jonay, Kun W. Kim, Frank Pollmann +1
Chaotic many-body spectra are expected to densely fill their energy window. We show that constrained spin chains with chiral symmetry evade this expectation by hosting an exponenti…
Quantum chaos and the holographic principle
Alexander Altland, Julian Sonner
Recent years have witnessed tremendous progress in developing a fine-grained low-dimensional holographic correspondence, specifically the construction of quantum mechanical boundar…
Continuum field theory of matchgate tensor network ensembles
Maksimilian Usoltcev, Carolin Wille, Jens Eisert +1
Tensor networks provide discrete representations of quantum many-body systems, yet their precise connection to continuum field theories remains relatively poorly understood. Invoki…
Freeness Reined in by a Single Qubit
Alexander Altland, Francisco Divi, Tobias Micklitz +1
Free probability provides a framework for describing correlations between non-commuting observables in complex quantum systems whose Hilbert-space states follow maximum-entropy dis…
Path integral approach to quantum thermalization
Alexander Altland, Kun Woo Kim, Tobias Micklitz
We introduce a quasiclassical Green function approach describing the unitary yet irreversible dynamics of quantum systems effectively acting as their own environment. Combining a v…
The universality class of the first levels in low-dimensional gravity
Alexander Altland, Jeremy van der Heijden, Tobias Micklitz +2
We investigate the physics of a small group of quantum states defined above the sharply defined ground state of a chaotic ensemble. This `universality class of the first levels' (U…
Statistics of the Random Matrix Spectral Form Factor
Alex Altland, Francisco Divi, Tobias Micklitz +2
The spectral form factor of random matrix theory plays a key role in the description of disordered and chaotic quantum systems. While its moments are known to be approximately Gaus…
Disordered topological crystalline phases
Adam Yanis Chaou, Mateo Moreno-Gonzalez, Alexander Altland +1
The imposition of crystalline symmetries is known to lead to a rich variety of insulating and superconducting topological phases. These include higher-order topological phases and…
Chaotic fluctuations in a universal set of transmon qubit gates
Daniel Basilewitsch, Simon-Dominik Börner, Christoph Berke +3
Transmon qubits arise from the quantization of nonlinear resonators, systems that are prone to the buildup of strong, possibly chaotic, fluctuations. Such instabilities will likely…
