Dynamical structure factor from weak measurements

June 25, 2025
Author(s)
Emine Altuntas, Rosaria Gabriella Lena, Stuart Flannigan, Ian Spielman, Andrew Daley
Much of our knowledge of quantum systems is encapsulated in the expectation value of Hermitian operators, experimentally obtained by averaging projective measurements. However, dynamical properties are often described by products of operators evaluated at

Weak-Measurement-Induced Heating in Bose-Einstein Condensates

June 23, 2023
Author(s)
Emine Altuntas, Ian Spielman
Ultracold atoms are an ideal platform for understanding system-reservoir dynamics of many-body systems. Here, we study quantum back-action in atomic Bose-Einstein condensates, weakly interacting with a far-from resonant, i.e., dispersively interacting

Quantum back-action limits in dispersively measured Bose-Einstein condensates

April 8, 2023
Author(s)
Ian Spielman, Emine Altuntas
A fundamental tenet of quantum mechanics is that measurements change a system's wavefunction to that most consistent with the measurement outcome, even if no observer is present. Weak measurements produce only limited information about the system, and as a
