Fig. 6: Phenomenon of the highly-asymmetric resonant tunneling.
From: Few-fermion resonant tunneling and underbarrier trapping in asymmetric potentials
For the L = 4 system with h = 20J, (a) a doublon initially placed on the site before the barrier and a spin-↑ fermion placed after it. We show the expectation values of (b) \(\langle {\hat{n}}_{L,\downarrow }\rangle\), and (c) \(\langle {\hat{n}}_{j,\downarrow }\rangle\) (with values color-coded on a logarithmic scale) as a function of time. d The time-averaged expectation value of \(\langle {\hat{n}}_{L,\downarrow }\rangle\) (with T = 100/J) as a function of the interaction amplitude U. The circle in the schematic barrier in (c) illustration indicates the site j* where the potential is h/2 = U.
