Quasiparticle projection method for dynamically unstable Bose-Einstein condensates
Asier Izquierdo, Maria Arazo, SofÃa MartÃnez-Garaot +1
We present a general formalism for performing a time-dependent Bogoliubov analysis of a dynamically unstable Bose-Einstein condensate, which extends the quasiparticle projection me…

Numerically Optimizing Shortcuts to Adiabaticity: A Hybrid Control Strategy
Bo Xing, Jesús G. Parejo, SofÃa MartÃnez-Garaot +2
Achieving fast, excitation-free quantum control is a vital challenge in modern quantum technologies. In many cases, shortcuts to adiabaticity enable fast adiabatic-like protocols,…

Impact of Force Noise on the Visibility of STA-Based Atom Interferometers
SofÃa MartÃnez-Garaot, I. Lizuain, A. Rodriguez-Prieto +1
In a previous work, we designed a compact atom interferometer to measure homogeneous constant forces guiding the arms via shortcuts to adiabatic paths. Within this scheme we drive…
