Spectral Edge Rigidity of Quantum Chaotic States
Joaquim Telles de Miranda, Tobias Micklitz
We determine the distribution of fidelity susceptibility for chaotic eigenstates at the spectral edge of Gaussian random-matrix ensembles. Previous work showed that, in the unitary…
Theory of Anderson localization on the hyperbolic plane
Alexander Altland, Tobias Micklitz, Devasheesh Sharma +2
The two-dimensional hyperbolic plane, , is an unusual system in that dimensionality changes with scale: locally two-dimensional and planar at short distances, but eff…
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…
Simulation-Free Fidelity Estimation via Quantum Output Order Statistics
Tobias Micklitz
We introduce a simulation-free method to estimate the fidelity of large quantum circuits based on the order statistics of measured output probabilities from highly entangled, chaot…
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…
