Effective field theories of dissipative fluids with one-form symmetries
Shreya Vardhan, Sašo Grozdanov, Samuel Leutheusser +1
A system with a one-form global symmetry at finite temperature can be viewed as a dissipative fluid of string-like objects. In this work, we classify and construct the most general…
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…
Petz recovery from subsystems in conformal field theory
Shreya Vardhan, Annie Y. Wei, Yijian Zou
We probe the multipartite entanglement structure of the vacuum state of a CFT in 1+1 dimensions, using recovery operations that attempt to reconstruct the density matrix in some re…
The black hole interior from non-isometric codes and complexity
Chris Akers, Netta Engelhardt, Daniel Harlow +2
Quantum error correction has given us a natural language for the emergence of spacetime, but the black hole interior poses a challenge for this framework: at late times the apparen…
Mixed-state entanglement and information recovery in thermalized states and evaporating black holes
Shreya Vardhan, Jonah Kudler-Flam, Hassan Shapourian +1
We study the universal behavior of quantum information-theoretic quantities in thermalized isolated quantum many-body systems and evaporating black holes. In particular, we study a…
Bound entanglement in thermalized states and black hole radiation
Shreya Vardhan, Jonah Kudler-Flam, Hassan Shapourian +1
We study the mixed-state entanglement structure of chaotic quantum many-body systems at late times using the recently developed . A rich entangl…
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…
