Excited that our observation of an unexpected sort of indistinguishability-driven #quantum hydrodynamics
(a spinoff [sorry, couldn't help self] of our #TunnelingTime project)
is now out in @PhysRevLett !

@QuantumAephraim @grantwmckinney Perhaps, though the irony is that the figure is from a paper in which the authors argue that times based on weak values have little meaning

@QuantumAephraim And the subjects that really don't want to go through, get pushed through faster

The red-light effect in action!

In a nutshell: @DavidCSpierings found the harder it is for a quantum particle to get across a barrier, the more quickly those who succeed do it!

@orzelc @VergaraLautaro @QuantumAephraim @PhysRevLett @uoftphysics @CQIQC_Toronto I'd hope the answer is becoming less and less interpretation-dependent. Our measurements implement a clock carried by each tunneling particle, which starts and stops when the particles enter and exit the barrier.

Come hear @DavidCSpierings talk about δ-kick cooling of scale-invariant #QuantumGases this Friday:

Had a fun time collaborating with Prof. del Campo's group @uni_lu ! A technique we've used in the lab @uoftphysics for years to cool atoms below 1nK turns out to be equivalent to a broad class of time-optimal protocols! https://t.co/9yOR9O0wdN

Ok, so this is where march meeting shines. Martinis, Monroe... a lot of industrial heavy hitters in one session. And some tough anonymous questions thanks to the virtual meeting

[David C Spierings @DavidCSpierings]

Very excited to be giving a talk today at APS March Meeting about our recent experimental results. Come check out session C28 at 4pm EST! https://t.co/YrlwtqZxbm @APSMeetings #apsmarch

@ultracold_org @dajmeyer @QuantumAephraim These times are extracted from a clock hand that lives in a 3D space. On any individual shot, we measure one-component (x,y,z) of that hand. About 100 shots each for the lowest energies
