Stabilizer complexity and the Python's lunch
Abhirup Bhattacharya, Jatin Narde, Onkar Parrikar +1
In this note, we study the stabilizer complexity of the reduced density matrix corresponding to one side of a partially entangled thermal (PET) state with fixed energy boundary con…
York time in JT gravity
Onkar Parrikar, Sunil Kumar Sake
The paper studies York time as an internal clock in two‑dimensional JT gravity, calculating the Hartle‑Hawking wavefunction as a function of this time and showing it satisfies a Sc…
Wigner negativity in Krylov space and emergent semiclassicality
Vijay Balasubramanian, Pawel Caputa, Onkar Parrikar +1
We propose that the Krylov basis gives a semiclassical representation of dynamics in general large-, complex, many-body systems. As a probe of this semiclassicality, we study th…
Fortuity and Complexity in a Simple Quark Model
Jackson R. Fliss, Vishnu Jejjala, Onkar Parrikar
We observe and elaborate on a structural similarity between the categorization of monotone and fortuitous BPS operators in supersymmetric theories and gauge invariant quark operato…
Entanglement spreading and emergent locality in Brownian SYK chains
Jatin Narde, Onkar Parrikar, Harshit Rajgadia +1
The Ryu-Takayanagi (RT) formula and its interpretation in terms of quantum error correction (QEC) implies an emergent locality for the spread of quantum information in holographic…
Modular Witten Diagrams and Quantum Extremality
Abhirup Bhattacharya, Onkar Parrikar
We study entanglement entropy for ball-shaped regions in excited states of holographic conformal field theories. The excited states are prepared by the Euclidean path integral in t…
