Atom interferometers can be used to measure accelerations with a wide spectrum of possible applications[1-3]. In this kind of set-up, absolute measurements can be significantly limited by vibration noise. Conversely, acceleration gradients can be measured in a differential configuration by two interferometers that share a common reference frame. Vibration noise, affecting the two phase shifts...
In the present talk, I present some recent theoretical and experimental results on the physics of [coherently coupled Bose-Einstein condensates][1] (BECs). The Ising-like ferromagnetic transition and the elementary excitations of the system are reviewed in order to introduce the phenomenon of bubble formation due to the metastability in the presence of the ferromagnetic critical point. The...
I present a method to introduce a measurement postulate in Quantum Field Theory (QFT) in Minkowski spacetime using Unruh-DeWitt detectors and algebraic tools. Beginning with a review of the detector-based measurements for QFT presented by J. Polo-Gomez, J. J. Garay, and E. Martin-Martinez (Phys. Rev. D 105, 2022), I demonstrate how this scheme can be extended to induce localised Kraus...
We investigate the two-point correlation functions that characterize the low-energy properties of inhomogeneous superfluids. Employing a covariant formalism and an appropriate perturbative expansion we determine the correlation functions in an arbitrary inhomogeneous background. Our result apply to standard non-relativistic superfluids, realizable in laboratory, as well as to relativistic...
The Sachdev-Ye-Kitaev (SYK) model describes a strongly-correlated quantum many-body system consisting of N Majorana fermions with random all-to-all q-body interactions, exhibiting several intriguing properties. Notably, the SYK model displays maximal scrambling of mutual information and maximal quantum chaos. Additionally, the model is of significant interest in the context of the AdS/CFT...
