A team has now demonstrated a missing hallmark of superfluidity, namely the existence of quantized vortices as system's response to rotation. They have observed tiny quantum vortices in the ...
The state of matter can be produced artificially in ultracold, dipolar quantum gases. A team has now demonstrated a missing hallmark of superfluidity, namely the existence of quantized vortices as ...
While researchers have probed various aspects of superfluid behavior, such as phase coherence and gapless Goldstone modes, direct evidence of one of superfluidity's defining features – quantized ...
