Congrats to Jonas Glatthard for his first published paper! And he did it in style, in #QuantumJournal no less.

"Bending the rules of low-temperature thermometry with periodic driving"

Wan to get the gist of it? A thread🧵

#QuantumThermometry is HARD. Not just in practice, but even in principle.

As one approaches the absolute zero, the noise-to-signal ratio of temperature estimates diverges.

Hence, it does matter, how fast is this precision loss.
At best, the relative error grows as a power law as T → 0. And the exponent is set by the low-frequency dependence of the density of states of the sample being measured.
