Extended Data Fig. 1: Calculated time density of the Larmor components Ï„y and Ï„z using the transfer-matrix method for a 135-nK Gaussian barrier.
From: Measurement of the time spent by a tunnelling atom within the barrier region
The black dashed lines indicate the 1/e2 radius of the Gaussian barrier and the grey lines show the classical turning points. The Larmor time Ï„y (or Ï„z) is obtained by integrating over space, taking into account the position-dependent coupling of the Raman beams.
