To illustrate the similarity, we compare in Fig. 39 the densities of normal-state transmission eigenvalues.
Random-Matrix Theory of Quantum Transport
Density of transmission eigenvalues through a normal region containing a potential barrier (transmission probability Γ = 0.4).
Random-Matrix Theory of Quantum Transport
T = 1/ cosh2 x. (The density has a cutoff at exponentially small transmission T ≈ exp(−2L/l), which is irrelevant for transport properties.) The derivation of Sec.

However, it should be noted that the transmission coeﬃcient of the 45◦ -asymmetric grain boundary junctions considered here is not particularly large, with current densities of only 100 − 1000A/cm2.
Experimental test for subdominant superconducting phases with complex order parameters in cuprate grain boundary junctions
T (ε) is not just the transmission coeﬃcient but rather the fully interacting density of states of the central region (including the electron-electron interaction or spin-ﬂip processes 10, for instance).

This paper focuses primarily on the information-theoretic limitations of low-density parity-check (LDPC) codes whose transmission takes place over a set of parallel channels.

The total transmission assumes integer values at an energy slightly above the maximum in 2D density of states as shown in the inset of Fig. 17.

Modeling of Nanoscale Devices
We have so far considered only the effect of externally applied ﬁelds on Rydberg EIT, but at sufﬁciently high atomic density and principal quantum number the dipole–dipole interactions between Rydberg atoms begin to play an important role and lead to a modiﬁcation of the optical transmission.
Non-linear optics using cold Rydberg atoms
The quantities A, B, C, D, are the ratios of the probability current densities of the speciﬁc transmission or reﬂection channels to the current of the incident particle, e.g. A = |JA/Jinc |, and so on.
Coherent exciton transport in semiconductors
From Eq. 14 we see the reason for that: nonvanishing transmission density at T → 1.
Generalized Ohm's law
The average widths occurring in the branching ratio bdec are related to average transmission coeﬃcients via hT i = 2πρ hΓi, with ρ being the average level density.
Cross section predictions for hydrostatic and explosive burning
The most relevant quantities for calculating the statistical model cross sections are reaction Q values, optical potentials, level densities, the electromagnetic transition strength (mostly E1 and M1) for photon transmission coeﬃcients, and information on low-lying discrete states.
