Repeated weak measurements: watching quantum correlations evolve
Emine Altuntas, Ian B. Spielman
Experimental access to many-body quantum systems is often limited by measurement backaction, and key dynamical properties are typically obtained by perturbing a system and measurin…
Dynamical Structure Factor from Weak Measurements
E. Altuntas, R. G. Lena, S. Flannigan +2
Much of our knowledge of quantum systems is encapsulated in the expectation value of Hermitian operators, experimentally obtained by averaging projective measurements. However, dyn…
Direct Calibration of Laser Intensity via Ramsey Interferometry for Cold Atom Imaging
Emine Altuntas, Ian B. Spielman
A majority of ultracold atom experiments utilize resonant absorption imaging techniques to obtain the atomic density. To make well-controlled quantitative measurements, the optical…
Weak-Measurement-Induced Heating in Bose-Einstein Condensates
Emine Altuntas, Ian B. 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, weak…
Quantum Back-action Limits in Dispersively Measured Bose-Einstein Condensates
Emine Altuntas, Ian B. Spielman
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. W…
Self-Bayesian Aberration Removal via Constraints for Ultracold Atom Microscopy
Emine Altuntas, Ian B. Spielman
High-resolution imaging of ultracold atoms typically requires custom high numerical aperture (NA) optics, as is the case for quantum gas microscopy. These high NA objectives involv…
Demonstration of a Sensitive Method to Measure Nuclear Spin-Dependent Parity Violation
Emine Altuntas, Jeffrey Ammon, Sidney B. Cahn +1
Nuclear spin-dependent parity violation (NSD-PV) effects in atoms and molecules arise from boson exchange between electrons and the nucleus, and from the magnetic interaction…
Measuring Nuclear Spin Dependent Parity Violation With Molecules: Experimental Methods and Analysis of Systematic Errors
Emine Altuntas, Jeffrey Ammon, Sidney B. Cahn +1
Nuclear spin-dependent parity violation (NSD-PV) effects in atoms and molecules arise from boson exchange between electrons and the nucleus, and from the magnetic interaction…
Dynamics of Few Co-rotating Vortices in Bose-Einstein Condensates
R. Navarro, R. Carretero-Gonzalez, P. J. Torres +5
We study the dynamics of small vortex clusters with few (2--4) co-rotating vortices in Bose-Einstein condensates by means of experiments, numerical computations, and theoretical an…
