Aperiodicity is sufficient for macroscopic thermalization
Amit Vikram
We identify a general mechanism for the finite-time thermalization of macroscopic observables, such as coarse-grained charge densities, in terms of elementary forms of the quantum…
Non-perturbative saturation of Krylov complexity, and its implications in quantum gravity
Andrew Lucas, Amit Vikram
The paper investigates Krylov state complexity in finite-dimensional quantum systems, showing it saturates shortly after the Heisenberg time for low‑energy states, and discusses th…
Provable quantum thermalization without statistical averages
Amit Vikram
We develop a rigorous system-agnostic method to predict quantum thermalization in an overwhelming fraction of accessible pure states in a many-body system, entirely in terms of cer…
Bidirectional teleportation using scrambling dynamics: a practical protocol
Amit Vikram, Edwin Chaparro, Muhammad Miskeen Khan +3
We show that quantum information scrambling can enable a generic SWAP gate between collective degrees of freedom in systems without universal local control. Our protocol combines t…
On the reconstruction map in JT gravity
Chris Akers, Andrew Lucas, Amit Vikram
An open question in AdS/CFT is how to reconstruct semiclassical bulk operators precisely enough that non-perturbative quantum effects can be computed. We propose a set of physicall…
Bypassing eigenstate thermalization with experimentally accessible quantum dynamics
Amit Vikram
Eigenstate thermalization has played a prominent role as a determiner of the validity of quantum statistical mechanics since von Neumann's early works on quantum ergodicity. Howeve…
