A recent paper by Gunn–Allison–Abbott (GAA) [L.J. Gunn et al., Scientific Reports 4 (2014) 6461] argued that the Kirchhoff-law–Johnson-noise (KLJN) secure key exchange system could experience a severe information leak. Here we refute their results and demonstrate that GAA’s arguments ensue from a serious design flaw in their system. Specifically, an attenuator broke the single Kirchhoffloop int...

The statistical mechanical investigation of violent relaxation (LyndenBell 1967) is extended to indistinguishable objects. It is found that, coincidentally, the equilibrium distribution is the same as that obtained for classical objects. For massive neutrinos, the Tremaine & Gunn (1979) phase space bound is revisited and reinterpretated as the limit indicating the onset of degeneracy related to...

This work has as main objective the integration of planar Gunn diodes and high electron mobility transistors (HEMTs) on the same chip for the realisation of high-power oscillators in the millimeter-wave regime. By integrating the two devices, we can reinforce the high frequency oscillations generated by the diode using a transistor-based amplifier. The integration of the planar Gunn diode and t...

In October 1900, Reverend John Gunn reflected on an opera staged for the benefit of his Atlanta parish: “The training was long and tedious; expenses enormous. I got typhoid worrying over thing. Expense production: $589. Tickets, etc.: $500. Loss: $89.” While Father eventually recovered from typhus fever continued staging productions cultural parishioners, he learned to rely wealthy patrons fina...
