Quantum master equation with balanced gain and loss
Dennis Dast, Daniel Haag, Holger Cartarius +1
We present a quantum master equation describing a Bose-Einstein condensate with particle loss on one lattice site and particle gain on the other lattice site whose mean-field limit…
Dipolar Bose-Einstein condensates in a PT-symmetric double-well potential
Rüdiger Fortanier, Dennis Dast, Daniel Haag +4
We investigate dipolar Bose-Einstein condensates in a complex external double-well potential that features a combined parity and time-reversal symmetry. On the basis of the Gross-P…
A Bose-Einstein Condensate with -Symmetric Double-Delta Function Loss and Gain in a Harmonic Trap: A Test of Rigorous Estimates
Daniel Haag, Holger Cartarius, Günter Wunner
We consider the linear and nonlinear Schrödinger equation for a Bose-Einstein condensate in a harmonic trap with -symmetric double-delta function loss and gain terms. We…
Stability of Bose-Einstein condensates in a symmetric double- potential close to branch points
Andreas Löhle, Holger Cartarius, Daniel Haag +3
A Bose-Einstein condensate trapped in a double-well potential, where atoms are incoupled to one side and extracted from the other, can in the mean-field limit be described by the n…
