Orbital angular momentum dynamics of Bose-Einstein condensates trapped in two stacked rings
Eloi Nicolau, Jordi Mompart, Bruno Juliá-Díaz +1
We investigate the stability and dynamics of the orbital angular momentum modes of a repulsive Bose-Einstein condensate trapped in two tunnel-coupled rings in a stack configuration…
The Hellmann-Feynman theorem at finite temperature
Marina Pons, Bruno Juliá-Díaz, Arnau Rios +2
We present a simple derivation of the Hellmann-Feynman theorem at finite temperature. We illustrate its validity by considering three relevant examples which can be used in quantum…
Creation of entangled atomic states by an analogue of the Dynamical Casimir Effect
K. Lange, J. Peise, B. Lücke +7
If the boundary conditions of the quantum vacuum are changed in time, quantum field theory predicts that real, observable particles can be created in the initially empty modes. Her…
Semiclassical approach to finite temperature quantum annealing with trapped ions
David Raventós, Tobias Graß, Bruno Juliá-Díaz +1
Recently it has been demonstrated that an ensemble of trapped ions may serve as a quantum annealer for the number-partitioning problem [Nature Comm. DOI: 10.1038/ncomms11524]. This…
Twist-and-Turn Spin Squeezing in Bose-Einstein Condensates
W. Muessel, H. Strobel, D. Linnemann +3
We experimentally demonstrate an alternative method for the dynamic generation of atomic spin squeezing, building on the interplay between linear coupling and nonlinear phase evolu…
