Free mutual information and higher-point OTOCs
Shreya Vardhan, Jinzhao Wang
We introduce a quantity called the free mutual information (FMI), adapted from concepts in free probability theory, as a new physical measure of quantum chaos. This quantity captur…
Chirality, magic, and quantum correlations in multipartite quantum states
Shreya Vardhan, Bowen Shi, Isaac H. Kim +1
We introduce a notion of chirality for generic quantum states. A chiral state is defined as a state which cannot be transformed into its complex conjugate in a local product basis…
Estimating time in quantum chaotic systems and black holes
Haifeng Tang, Shreya Vardhan, Jinzhao Wang
We characterize new universal features of the dynamics of chaotic quantum many-body systems, by considering a hypothetical task of "time estimation." Most macroscopic observables i…
Local dynamics and the structure of chaotic eigenstates
Zhengyan Darius Shi, Shreya Vardhan, Hong Liu
We identify new universal properties of the energy eigenstates of chaotic systems with local interactions, which distinguish them both from integrable systems and from non-local ch…
Void formation in operator growth, entanglement, and unitarity
Hong Liu, Shreya Vardhan
The structure of the Heisenberg evolution of operators plays a key role in explaining diverse processes in quantum many-body systems. In this paper, we discuss a new universal feat…
