An interesting possibility about FQHE – in the context of LENR, is that there could be a transient version inside a Casimir cavity.
The phenomenon of the fractional quantum Hall effect (FQHE) occurs when electrons are contained in two dimensions, cooled to near absolute zero temperature, and exposed to a strong magnetic field. On the surface, it would seem that this cannot happen in LENR as a static phenomenon, as the temperature is way too high… but electrons confined inside a dielectric Casimir cavity, which is inside a metal matrix - even at 500C could experience a transient version of FQHE in a situation where SPP are supplying the strong magnetic field, and virtual photon exclusion by the cavity walls provides the cooling effect, and the inside of a Casimir cavity can be modeled as 2-D. The first and last are found in prior scientific studies, but the cooling effect is not seen in the literature, AFAIK. Jones Kevin, Not sure what direction you are going with this – but in 2010 – we were talking about fractional electron charge (AKA: FQHE) as being the driving force behind one form of LENR – at least the non-nuclear version of LENR and possibly the Mills’ version - which happens at the nanoscale or in Casimir cavities. Several times since then, the fractional Hall effect has been tied to thermal anomalies. https://www.mail-archive.com/vortex-l%40eskimo.com/msg40603.html “I won't go into all of the lore of monatomic hydrogen, going back to Langmuir, or the Mills' version of fractional hydrogen called the hydrino - except to say that there is another possibility that encompasses both of these phenomena - and it can explain other "hot hydrogen" (HH) phenomena or anomalies, so long as we limit it to two dimensions. This possibility would also suggest that a Casimir cavity is or acts 'as if' it were a two dimensional space. There are a number of papers on this second prerequisite, many of them by Calloni, but I will save that for another time. The argument is sound. According to Laughlin, electrons can form an exotic state with fractional charge in two dimensions. Unlike the putative hydrino, this seemingly odder beast is accepted by the mainstream. It has even won a Nobel. Consequently, taking this bit of insight to the next level - given that all electrons are happy to form pairs, it is suggested that HH is itself related to FQHE via paired electrons.”
