- Abstract: We introduce kicked $p$-spin models describing a family of transverse
Ising-like models for an ensemble of spin-$1/2$ particles with all-to-all
$p$-body interaction terms occurring periodically in time as delta-kicks. This
is the natural generalization of the well-studied quantum kicked top
($p$=2)[Haake, Ku\'s, and Scharf, Z. Phys. B 65, 381 (1987)]. We fully
characterize the classical nonlinear dynamics of these models, including the
transition to global Hamiltonian chaos. The classical analysis allows us to
build a classification for this family of models, distinguishing between $p=2$
and $p>2$, and between models with odd and even $p$'s. Quantum chaos in these
models is characterized in both kinematic and dynamic signatures. For the
latter we show numerically that the growth rate of the out-of-time-order
correlator is dictated by the classical Lyapunov exponent. Finally, we argue
that the classification of these models constructed in the classical system
applies to the quantum system as well.

We consider a class of Heisenberg all-to-all coupled spin models inspired by neutrino interactions in a supernova with $N$ degrees of freedom.
These models are characterized by a coupling matrix that is relatively simple in the sense that there are only a few, relative to $N$, non-trivial eigenvalues.

We identify two different classes: the near edge physics of sparse'' and the near edge of dense'' chaotic systems.
The distinction lies in the ratio between the number of a system's random parameters and its Hilbert space dimension.
While the two families share identical spectral correlations at energy scales comparable to the level spacing, the density of states and its fluctuations near the edge are different.

We analyze a model of qubits which we argue has an emergent quantum gravitational description similar to the fermionic Sachdev-Ye-Kitaev (SYK) model.
The model is known as the quantum $q$-spin model because it features $q$-local interactions between qubits.

As opposed to an assertion of previous studies, the entanglement dynamics in this non-Hermitian quantum system is very different from the one in its Hermitian counterpart.
