Kinda neat, but can it be used for anything?
You just know someone is going to either mis-hear or mispronounce this.
They’re using excitons once they form, to indicate the presence of these electrons. If you overload the capacitance of an exciton, you can have LENR.

[Vo]:Excitonic Collapse as the proximate cause of gain in LENR
Jones Beene Mon, 23 Jun 2014 08:08:55 -0700
To put this topic under its own subject heading …
An article turned up (“before its time”, literally) in Journal of
Electroanalytical Chemistry, Volume 727, 1 August 2014, Pages 53–58 which
could have relevance to LENR insofar as understanding the mechanics for gain
in some types of experiments – especially those where significant local
voltage fluctuations exist, since the voltage swings can be a function of
SPP formation or decay.

“Electrochemical supercapacitor behavior of α-Ni(OH)2 nanoparticles…” by
Vijayakumar and Muralidharan. The authors claim that Ni(OH)2 nanoparticles
exhibit specific capacitance of over 500 F g−1 (paywall prohibits more
detail).
The relevant analogy would be electron/positron annihilation, which are much
higher energy. In the case of excitons, SPP, and LENR, it would be
electron/electron-hole collapse. The SPP during either formation or decay
would overload the capacitance of the exciton. The net energy is expected to
be similar to bandgap energy in the range of 2-4 eV per collapse in the form
of photons. The ultimate source of energy is still in dispute, but can
related to the Dirac sea of negative energy. An eV value that is often seen
or surmised is the violet or near UV photon of 3.4 eV since it is a Rydberg
fraction of positronium binding energy.
In the context of LENR, Ni-O coated nanospheres are available, and would
form nickel hydroxide on hydrogen exposure. Here is an image of a 10 uF cap
exploding (10 microfarad)

Presumably, a microgram of Ni hydroxide would have 50 times greater
explosive power than this image suggests, but of greater interest would be
to engineer the overloading of individual excitons, sequentially and in a
way that does not result in failure of the structure.
AFAIK no one has ever proposed before now that one form of LENR is built
upon the process of sequential voltage overloading of capacitive
nanoparticles in the form of excitons. In an exciton there is a “free
electron” and a “hole”. A positively-charged electron hole is generally
considered to be an abstraction for the location from which an electron was
moved. However, perhaps the electron hole is something more than abstraction
in LENR – for instance: being an interface with the Dirac sea of negative
energy where the “holes” therein may share more than the same name. The
Dirac hole and the exciton hole would thus be identical or connected by a
coupling mechanism.
Exciton collapse is known to happen. “Excitonic Collapse in Semiconducting
Transition Metal Dichalcogenides” by Rodin and Neto concerns semiconducting
transition metal crystals characterized by electron volt size band gaps,
spin-orbit coupling (SOC), and d-orbital character of its valence and
conduction bands. “We show that these materials carry unique exciton
quasiparticles (electron-hole bound states) with energy within the gap but
which can collapse in the strong coupling regime by merging into the band
structure continuum,
Another beauty of “excitonic collapse” for LENR theory is that this route to
gain merges well with the known and hypothetical features of the Dirac sea,
as explicated by the late Don Hotson.

It'd be interesting to study the (as it were) vibrational modes of the Wigner Crystal.
Or hey, for a large enough Crystal, whatever corresonds to "phonons"? (...or is that what the excitons are?)
"The team observed that when there was a specific number of electrons in each layer, they all stood mysteriously still. “Somehow, electrons inside the semiconductors could not move. "
OTOH, back in the early 80s the few times I rode the Red Line of the DC metro, I would observe much the same effect during rush hour...
The stench (worse than the hog pens in Coinjock, NC or the cattle pens in the Imperial Valley) made my wife just throw all the clothes away...

Whatever happened to Wigner’s sister?
