Delta- noise for weak tunneling in one-dimensional systems: Interactions versus quantum statistics

G Zhang, IV Gornyi, C Spånslätt - Physical Review B, 2022 - APS
We study delta-T noise—excess charge noise at zero voltage but finite temperature bias—
for weak tunneling in one-dimensional interacting systems. We show that the sign of the …
