Time Evolution of Multi-Party Entanglement Signals
Vijay Balasubramanian, Hanzhi Jiang, Simon F. Ross
We study the real-time dynamics of multi-party entanglement signals in chaotic quantum many-body systems including but not necessarily restricted to holographic conformal field the…
Variations on a Theme of Krylov
Vijay Balasubramanian, Pawel Caputa, Joan Simón
Spread complexity uses the distribution of support of a time-evolving state in the Krylov basis to quantify dispersal across accessible dimensions of a Hilbert space. Here, we desc…
Quantum complexity in gravity, quantum field theory, and quantum information science
Stefano Baiguera, Vijay Balasubramanian, Pawel Caputa +4
Quantum complexity quantifies the difficulty of preparing a state or implementing a unitary transformation with limited resources. Applications range from quantum computation to co…
Detecting Black Hole Microstates
Vijay Balasubramanian, William KL Chan, Chitraang Murdia
We demonstrate that the Euclidean two-point function of an appropriately chosen probe operator can detect the microstate of an asymptotically AdS black hole. This detection, which…
A universal animal communication tempo resonates with the receiver's brain
Guy Amichay, Vijay Balasubramanian, Daniel M. Abrams
During fieldwork in Thailand we observed nearly identical frequencies of co-located flashing fireflies and chirping crickets. Motivated by this, we perform a meta-analysis and show…
