Complexity from the reduced density matrix: a new diagnostic for chaos
We investigate circuit complexity to characterize chaos in multiparticle quantum systems. In the process, we take a stride to analyze open quantum...

Symmetries and spectral statistics in chaotic conformal field theories. Part II. Maass cusp forms and arithmetic chaos
We continue the study of random matrix universality in two-dimensional conformal field theories. This is facilitated by expanding the spectral form...

Sparse random matrices and Gaussian ensembles with varying randomness
We study a system of N qubits with a random Hamiltonian obtained by drawing coupling constants from Gaussian distributions in various ways. This...

Krylov complexity and spectral form factor for noisy random matrix models
We study the spectral properties of two classes of random matrix models: non-Gaussian RMT with quartic and sextic potentials, and RMT with Gaussian...

Krylov complexity for Jacobi coherent states
We develop computational tools necessary to extend the application of Krylov complexity beyond the simple Hamiltonian systems considered thus far in...

A Matrix Model for Flat Space Quantum Gravity
We take a step towards the non-perturbative description of a two-dimensional dilaton-gravity theory which has a vanishing cosmological constant and...

Anomalous localization in a kicked quasicrystal
Quantum transport can distinguish between dynamical phases of matter. For instance, ballistic propagation characterizes the absence of disorder,...

The Page curve for reflected entropy
We study the reflected entropy S R in the West Coast Model, a toy model of black hole evaporation consisting of JT gravity coupled to end-of-the-world...

Oscillations, Rhythms and Synchronized Time Bases: The Key Signatures of Life
The dynamic complexity of the living state as evident on viewing cells microscopically defies immediate comprehension. Experiment and theory now...

Quantum many-body scars and weak breaking of ergodicity
Thermalization is the inevitable fate of many complex quantum systems, whose dynamics allow them to fully explore the vast configuration space...

The resurgence of the plateau in supersymmetric \( \mathcal{N} \) = 1 Jackiw-Teitelboim gravity
Significant progresses have been made recently in understanding the spectral form factor of Jackiw-Teitelboim gravity, particularly at late times...

Towards the web of quantum chaos diagnostics
We study the connections between three quantities that can be used as diagnostics for quantum chaos, i.e., the out-of-time-order correlator (OTOC),...

A machine learning approach to detect aortic valve dysfunction through phase portrait feature extraction
The paper reports a novel method of early detection of heart valve dysfunction, drawing phase portrait and power spectral features of normal (NM) and...

Characteristics of Gas-Liquid Slug Flow in Microchannel by Instantaneous Liquid Film Thickness Measurement
This paper seeks to decipher the exact relationship between the liquid film thickness and the hydrodynamics of gas-liquid slug flows. An...

Wormholes and spectral statistics in the Narain ensemble
We study the spectral statistics of primary operators in the recently formulated ensemble average of Narain’s family of free boson conformal field...

Dissipative Optical Solitons: An Introduction
In this chapter we provide an introduction to the topic of this book. After a brief historical note on solitary waves, a special attention is paid to...

An Overview of Quantum Biology
Quantum mechanics has long been foundational in physics and chemistry, but biology has typically adhered to classical physics. Recent studies...

Mesoscale Magnetic Structures in Spiral Galaxies
Virtually all spiral galaxies host magnetic fields ordered at scales comparable to the galactic size (Beck et al., 1996; Beck, 2000, 2001)....

Astrophysics with the Laser Interferometer Space Antenna
The Laser Interferometer Space Antenna (LISA) will be a transformative experiment for gravitational wave astronomy, and, as such, it will offer...

Information and Randomness
The notion of randomness can be traced back to the same desire that has already been alluded to in the context of prediction within a social group:...
