The Ueda-Guinea model of a dissipative tunnel junction is investigated. This model accounts for final-state effects associated with single-electron tunneling. A quantum phase transition emerges, marking a boundary betweeninsulating (Coulomb blockade) and conducting phases. The system is analyzed by large-N techniques, self-consistent harmonic approximation, and Monte Carlo methods.

We investigate the behavior of an $N$-component quantum rotor coupled to a bosonic dissipative bath having a sub-Ohmic spectral density $J(\omega) \propto \omega^s$ with $s s>1/2$, we find nontrivial

Connecting the SYK Dots

We study a putative (strange) metal-to-insulator transition in a granular array of the Sachdev–Ye–Kitaev (SYK) quantum dots, each occupied by a large number N ≫ 1 of charge-carrying fermions.

TLDR
The effective conductance of an ultrasmall tunnel junction is calculated from the functional-integral description beyond the weak-coupling limit by employing the self-consistent harmonic approximation, and results indicate a possibility of a precipitous transition for ${R}_{N}$ of the order of $\frac{\ensuremath{\hbar}}{{e}^{2}}$.
