Reentrant localization in fractionally charged electron wave packets
Y. Yin
We investigate the localization transition in fractionally charged electron wave packets, which is injected into a quantum conductor by a single voltage pulse with arbitrary flux q…
Matrix-Valued Orthogonal Polynomials Related to a Class of Random Walk
P. Roman, S. Menchon, Y. Yin
The foundational work of Karlin and McGregor established a powerful connection between random walks with tridiagonal transition matrices and the theory of orthogonal polynomials. W…
Low-energy effective theory of localization-delocalization transition in noninteger-charged electron wave packets
Y. Yin
We present a low-energy effective theory to describe the localization-delocalization transition, which occurs for wave functions of electrons and holes injected individually by a v…
Localization-delocalization transition in non-integer-charged electron wave packets
Y. Yin
We investigate the wave function of electrons and holes injected by voltage pulses with non-integer flux quantum. We find that the wave function can be delocalized in the time doma…
