We numerically support the conjecture by studying the phase-space Husimi function and the position representation of resonance states of the chaotic standard map.

- Abstract: We conjecture that in chaotic quantum systems with escape the intensity
statistics for resonance states universally follows an exponential
distribution. This requires a scaling by the multifractal mean intensity which
depends on the system and the decay rate of the resonance state. We numerically
support the conjecture by studying the phase-space Husimi function and the
position representation of resonance states of the chaotic standard map, the
baker map, and a random matrix model, each with partial escape.

We show how classical dynamics describes resonance states of all decay rates in the semiclassical limit.
This result corresponds to the well-established quantum ergodicity for closed chaotic systems.

We develop a formalism for mapping the exact dynamics of an ensemble of disordered quantum systems onto the dynamics of a single particle propagating along a semi-infinite lattice.
This mapping provides a geometric interpretation on the loss of coherence when averaging over the ensemble and allows computation of the exact dynamics of the entire disordered ensemble in a single simulation.

quantum-dynamical scrambling [49.1574468325115]
A key conjecture about the evolution of complex quantum systems towards an ergodic steady state, known as scrambling, is that this process acquires universal features when it is most efficient.
We develop a single- parameter scaling theory for the spectral statistics in this scenario, which embodies exact self-similarity of the spectral correlations along the complete scrambling dynamics.
We establish that scaling predictions are matched by a privileged process, and serve as bounds for other dynamical scrambling scenarios, allowing one to quantify inefficient or incomplete scrambling on all timescales.

We prove a recent conjecture for open chaotic systems, which claims that resonance states are composed of two factors.
In particular, we demonstrate that one factor is given by universal exponentially distributed intensity fluctuations.
The other factor, supposed to be a classical density depending on the lifetime of the resonance state, is found to be very well described by a classical construction.

A class of generalized coherent states is determined for the distribution of excitations.
The statistics is uniquely sub-Poissonian for large values of the label.
As particular cases, truncated Wright generalized coherent states exhibit uniquely non-classical properties.

An initial state made by a local excitation of the paramagnetic ground state is considered.
A localization mechanism is found and the excitation remains close to its initial position at arbitrary times.

We consider an ensemble of Alkali atoms that are continuously optically pumped and probed.
Due to the collective scattering of photons at large optical depth, the steady state of atoms does not correspond to an uncorrelated tensor-product state.
We find and characterize regimes of Raman lasing, akin to the model of a superradiant laser.

We propose a measure of quantum state complexity defined by minimizing the spread of the wave-function over all choices of basis.
Our measure is controlled by the "survival amplitude" for a state to remain unchanged, and can be efficiently computed in theories with discrete spectra.
