What the article says around this equation
The cheapest of the three needs no such cooling at all. Christophe De Beule and collaborators showed that a slowly varying tilt horizon transmits carriers through Hawking-like thermal channels, and that the effect shows up as a peak in the ordinary two-terminal differential conductance, of order 2/h per conducting mode, whose position tracks the strain-set tilt slope directly [ 4 ] . Because the peak is a property of how carriers transmit through the tipped cone rather than a property of thermal equilibrium, it is present as soon as the horizon exists, with no requirement to cool below the analog Hawking temperature — the signature a first, warmer device should chase.
