Motivated by holographic complexity proposals as novel probes of black hole spacetimes,
we explore circuit complexity for thermofield double (TFD) states in free scalar quantum field …

The complex Fourier transform of the two-point correlator of the energy spectrum of a
quantum system is known as the spectral form factor (SFF). It constitutes an essential …

In this work, the term``quantum chaos''refers to spectral correlations similar to those found in
the random matrix theory. Quantum chaos can be diagnosed through the analysis of level …

A bstract At present, the measurements of\({R} _ {D^{\left (\ast\right)}}\) and RJ/ψ hint at new
physics (NP) in\(b\to c {\tau}^{-}\overline {v}\) decays. The angular distribution of\(\overline …

The search for a quantum theory of gravity has led to the discovery of quantum many-body
systems that are dual to gravitational models with quantum properties. The perhaps most …

We use the monodromy method to compute expectation values of an arbitrary number of
light operators in finitely excited (" heavy") eigenstates of holographic 2D CFT. For …

We extend the results of two of our papers [Phys. Rev. A 94, 041603R (2016) and Phys. Rev.
B 97, 060303R (2018)] that touch upon the intimately connected topics of quantum chaos …

A bstract We present a detailed quantitative analysis of spectral correlations in the Sachdev-
Ye-Kitaev (SYK) model. We find that the deviations from universal Random Matrix Theory …

We report a systematic investigation of universal quantum chaotic signatures in the
transverse field Ising model on an Erdős-Rényi network. This is achieved by studying local …

We investigate how the dynamical fluctuations of many-body quantum systems out of
equilibrium can be mitigated when they are opened to a dephasing environment. We …
