Scramblon loops
Douglas Stanford, Shreya Vardhan, Shunyu Yao
In large chaotic quantum systems, the butterfly effect is mediated by a collective field mode known as the ``scramblon.'' We study self-interactions of the scramblon in variant…
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…
Entanglement entropies of equilibrated pure states in quantum many-body systems and gravity
Hong Liu, Shreya Vardhan
We develop a universal approximation for the Renyi entropies of a pure state at late times in a non-integrable many-body system, which macroscopically resembles an equilibrium dens…
A dynamical mechanism for the Page curve from quantum chaos
Hong Liu, Shreya Vardhan
If the evaporation of a black hole formed from a pure state is unitary, the entanglement entropy of the Hawking radiation should follow the Page curve, increasing from zero until n…
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…
