The sparse version of the Sachdev-Ye-Kitaev (SYK) model reproduces essential features of
the original SYK model while reducing the number of disorder parameters. In this Research …

The saturation of a recently proposed universal bound on the Lyapunov exponent has been
conjectured to signal the existence of a gravity dual. This saturation occurs in the low …

Krylov complexity has recently emerged as a new paradigm to characterize quantum chaos
in many-body systems. However, which features of Krylov complexity are prerogative of …

A bstract We use a combination of analytical and numerical methods to study out-of-time
order correlators (OTOCs) in the sparse Sachdev-Ye-Kitaev (SYK) model. We find that at a …

Random recursive hypergraphs (RRHs) grow by adding, at each step, a vertex and an edge
formed by joining the new vertex to a randomly chosen existing edge. The model is …

Quantum informatic quantities such as entanglement entropy are useful in detecting
quantum phase transitions. Recently, a new entanglement measure called pseudo-entropy …

In this paper, we investigate different thermodynamic properties of TT¯+ JT¯ deformed
Schwarzian theory and its different gravitational perspectives. First, we compute the partition …

A quantum advantage can be achieved in the unitary charging of quantum batteries if their
cells are interacting. Here, we try to clarify with some analytical calculations whether and …

The spectral form factor (SFF) plays a crucial role in revealing the statistical properties of
energy-level distributions in complex systems. It is one of the tools to diagnose quantum …

Quantum dynamical localization occurs when quantum interference stops the diffusion of
wave packets in momentum space. The expectation is that dynamical localization will occur …
