The quantum kicked rotor had been widely used for studying quantum chaos and the physics of Anderson localization. It is shown that QKR can be used to design a quantum algorithm to perform unstructured search. This is illustrated through amplitude am

We show that a Bose-Einstein Condensate (BEC) launched with non-zero initial momentum into a periodically kicked optical lattice creates an asymmetrically localized momentum distribution in a moving frame with a small initial current. This asymmetric

Quantum resonance in the paradigmatic kicked rotor system is a purely quantum effect that ignores the state of underlying classical chaos. In this work, it is shown that quantum resonance leads to superlinear entanglement production. In $N$-interacti

Advancements in technology have recently allowed us to collect and analyse large-scale fine-grained data about human performance, drastically changing the way we approach sports. Here, we provide the first comprehensive analysis of individual and tea

Elections for public offices in democratic nations are large-scale examples of collective human behavior. As a statistical physics problem with complex interactions among agents, we can anticipate that universal macroscopic patterns can emerge indepe

A host of dynamical measures of quantum correlations -- out-of-time ordered correlators, Loschmidt echo, generalized entanglement and observational entropy -- are useful to infer about the underlying classical chaotic dynamics in quantum regime. In t

The study of interacting dynamical systems continues to attract research interest in various fields of science and engineering. In a collection of interacting particles, the interaction network contains information about how various components intera

An important task in quantum generative machine learning is to model the probability distribution of measurements of many-body quantum systems. Classical generative models, such as generative adversarial networks (GANs) and variational autoencoders (

Despite the periodic kicks, a linear kicked rotor (LKR) is an integrable and exactly solvable model in which the kinetic energy term is linear in momentum. It was recently shown that spatially interacting LKRs are also integrable, and results in dyna

In the usual quantum tunneling, a low-energy quantum particle penetrates across a physical barrier of higher potential energy, by traversing a classically forbidden region, and finally escapes into another region. In an analogous scenario, a classica
