We determine the phase diagram of strongly correlated fermions in crossover from Bose-Einstein condensates molecules (BEC) to Cooper pairs (BCS) utilizing an artificial neural network. By applying advanced image recognition techniques momentum distribution fermions, a quantity which has been widely considered as featureless for providing information about condensed state, we measure critical temperature and show that it exhibits maximum on bosonic side crossover. Additionally, backanalyze...
The authors investigate the response of a strongly-interacting superfluid Fermi gas to spin-flip and corresponding change interaction strength. They observe decay revival condensed fraction shape oscillations gas.
Cold atom experiments commonly use broad magnetic Feshbach resonances to manipulate the interaction between atoms. In order induce quantum dynamics by a change in strength, rapid (∼μs) field changes over several tens of Gauss are required. Here, we present compact design coil and its control circuit for up 36 G 3 µs. The setup comprises two concentric solenoids with minimal space requirements, which can be readily added existing apparatuses. This makes observation non-equilibrium physics accessible.
We study the critical temperature of superfluid phase transition strongly interacting fermions in crossover regime between a Bardeen-Cooper-Schrieffer superconductor and Bose-Einstein condensate dimers. To this end, we employ technique unsupervised machine learning using an autoencoder neural network, which directly apply to time-of-flight images fermions. extract from trend changes data distribution revealed latent space bottleneck.
We present a novel approach to estimating physical properties of objects from video. Our consists physics engine and correction estimator. Starting the initial observed state, object behavior is simulated forward in time. Based on behavior, estimator then determines refined parameters for each object. The method can be iterated increased precision. generic, as it allows use an arbitrary-not necessarily differentiable-physics For latter, we evaluate both gradient-free hyperparameter...
