Different fractional charges from auto- and cross-correlation noise in quantum Hall states without upstream modes
Physical Review Letters(2023)
摘要
Fractional charges of anyons can be extracted from shot noise in two ways.
One can use either the auto-correlation noise of the current in one drain or
the cross-correlation noise between two drains on the two sides of the device.
The former approach typically overestimates the charge. This may happen due to
upstream edge modes. We propose a mechanism for the excess auto-correlation
noise without upstream modes. It applies to systems with multiple
co-propagating edge modes and assumes that the noise is measured at a low but
non-zero frequency.
