Physical Review A, 2013•APSIn this Rapid Communication, we describe how the presence of the third dimension may
break the scale invariance in a two-dimensional Bose gas in a pancake-shaped trap. From
the two-dimensional perspective, the possibility of a weak spilling of the atomic density
beyond the ground state of the confinement alters the two-dimensional chemical potential; in
turn, this correction no longer supports scale invariance. We compare experimental data
with numerical and analytic perturbative results and find a good agreement.
