Meissner effect in a bosonic ladder
We investigate the effect of a magnetic field on a bosonic ladder. We show that such a

Spontaneous increase of magnetic flux and chiral-current reversal in bosonic ladders: Swimming against the tide
The interplay between spontaneous symmetry breaking in many-body systems, the wavelike
nature of quantum particles and lattice effects produces an extraordinary behavior of the …
