Yes they can. In fact this could be important for LENR, should it be broad enough to include other boson quasiparticles, such as the magnon.
The definitions are similar: polaritons are quasiparticles resulting from strong coupling of electromagnetic waves with an electric or magnetic dipole-carrying excitation. The magnon could be imagined to be the subset of that - where the coupling is only magnetic. However, it may be only a partial subset with other features included.
Polaritons describe the dispersion of light (photons) with an interacting phonon resonance; while the magnon would describe the dispersion of spin current with an interacting resonance.
Using the same general terms, superconductivity where the Cooper pair is the boson, would describe the dispersion of charge within an interacting phonon resonance. (the last is my interpretation, which may not be correct).
Thus we have a linking of three BEC phenomena which may happen either at room temperature or close- in the case of the RTSC. From: Axil Axil

Can those interested in LENR draw any lessons from this formulation?

Bose-Einstein condensate created at room temperature
Instead of atoms, condensation was achieved using quasiparticles.

Bose-Einstein condensation is a dramatic phenomenon in which many particles act as though they were a single entity. The first Bose-Einstein condensate produced in the laboratory used rubidium atoms at very cold temperatures—work that was awarded the 2001 Nobel Prize in physics. Other materials, like superconductors, exhibit similar behavior through particle interactions.
These systems typically require temperatures near absolute zero. But Ayan Das and colleagues have now used a nanoscale wire to produce an excitation known as a polariton. These polaritons formed a Bose-Einstein condensate at room temperature, potentially opening up a new avenue for studying systems that otherwise require expensive cooling and trapping.
Bosons are part of a large class of particles that can have the same quantum configuration or state. This is in contrast to the fermions, the category including electrons, protons, and neutrons, which resist having the same state. (This resistance, known as the Pauli exclusion principle, leads to the presence of different energy states, or orbitals, occupied by the electrons of atoms.) At extremely low temperatures, bosons can coalesce into a single quantum system known as a Bose-Einstein condensate (BEC), named for Satyendra Nath Bose and Albert Einstein.
Many atoms are bosons, though this characteristic doesn't generally make any difference except at high density or very low temperatures. However, thanks to the wonders of quantum physics, interactions within materials can produce quasiparticles. These are excitations that act like particles, but don't exist independent of the medium in which they occur.
As with normal particles, quasiparticles are either fermions or bosons, obeying the same general rules as their free cousins. For example, one widely accepted model for superconductivity describes the phenomenon as a Bose-Einstein condensation of quasiparticles formed by pairs of electrons. As with atomic BECs, quasiparticle BECs tend to form under very cold temperatures.
Another quasiparticle can be formed by the interactions between photons and excitations in a material. The resulting polaritons are low-mass bosons that should be able to condense at higher temperatures—possibly including room temperature. One signature of a polariton BEC is the production of coherent light—effectively, the quasiparticles act like a laser. Several experiments have created polariton BECs, though still at relatively cold temperatures.
The current study embedded a very thin wire—a nanowire—in a cavity designed to produce standing waves of microwave photons. The nanowire was an alloy of aluminum, gallium, and nitrogen, but with varying amounts of aluminum. The irregular composition created a de facto "trap" for the polaritons. A wire of uniform composition couldn't form a BEC—fluctuations within the material would destroy the condensation, even at low temperatures.
To bypass this, the researchers gradually decreased the amount of aluminum in the alloy to zero in the center of the nanowire, then bookended the aluminum-free segment with a region containing a relatively high amount of aluminum. The microwaves from the cavity interacted with the material, generating polaritons. These drifted preferentially along the wire toward the aluminum-free zone, where they collected and condensed.
In other words, the electronic properties of the material itself replaced the need for cooling, allowing the quasiparticles to gather and condense into a BEC. The experimenters confirmed this effect by detecting the telltale light emission.
This experiment marked the first room-temperature BEC ever observed in the laboratory. While the authors didn't suggest any practical application, the potential for studying BECs directly is obvious. Without the need for cryogenic temperatures or the sorts of optical and magnetic traps that accompany atomic BECs, many aspects of Bose-Einstein condensation can potentially be probed far less expensively than before.

Because LENR is scientifically established, but is still in its infancy as an engineering field. Think of what would happen to AC electricity if Tesla died earlier, the invention of the polyphase motor would have taken decades. There’s been more than 14,000 LENR replications. I haven’t spent much inquisitiveness on Rossi lately, most of my references to his work have been something that was included in whatever LENR article is posted, and we’re not supposed to just remove references in articles. I posted LENR articles before Rossi and I’ll be posting them after he leaves the scene.
Fair enough.
P.S. Just so you know, I’m a Tesla fanatic. Hopefully no hanging out with pigeons for me though.
I thought it was going to be a moonshine thread, condensate.
Has your water heater arrived yet or is it still in the robotic factory that hasn’t been built yet?
I say we sink geothermal pipes down into the hot deep mantle for energy. This will power us for millennium untill the core solidifies and we lose our van Allen protection
But...but the Kecksburg Incident!
The acorn shaped craft with nazi runes! God man! The Mothership!
Might be, depending on what you think of LENR.
http://www.greatenergychallengeblog.com/2013/01/23/alleged-mafia-ties-cast-new-shadow-on-italys-renewables/ ~ citing this one because it cites a number of other articles about the same problem. I recall not long ago that folks here were arguing that one of the more public LENR experimenters was lying about the Italian mafia trying to push him out of business. So now we find that Kim’s theory is not improbable since, in fact, Bose-Enstein condensate can be manufactured in ordinary environmental room temperatures. So, Moonman62, what’s your relationship to any of this? Is it the mafia, or MIT, or what?
None of the results for those claimed 14k experiments were predictable, and they are not covered by any one theory that can make those predictions (For instance, a theory that can make a prediction of output based on input within a margin of error.). Therefore, LENR is not scientifically established.
Muon catalyzed cold fusion is scientifically established. One can use that for comparison.
I heard that the MIT bookstore was having a sale on Bose-Einstein Condensate traps.
Is that like Cro magnon or fillet magnon?
My LENR water heater will arrive 200 years before any hot-fusion water heater will hit the market.
Never once has any lurker followed up your ridiculous anti-science Luddite objections and said they were worth pursuing.
Thanks for bumping the thread

Lowering the temperature is equivalent to lasering off the back two rows of seats.
***I don’t see it that way. Lowering the temperature and taking energy away from the system is like taking sugar away from the kids & giving them Ritalin so they’ll settle down. A BEC is like getting 9 kids in 9 seats, whereas you’ve been talking about getting 3 kids into 9 seats because none of them still want to touch each other.
What they are doing in this experiment is creating a metastable configuration in which they create a single ground state, even though the system is not at low temperature. The bosons will then condense into that state. There is no "forcing" required; because there is only one state created by the experiment's design, the bosons condense into that state. There is no other place for them to go.
If they were fermions, this experiment would fail.
If your kids are fermions, you can yell "I'm going to turn this car around!" all day, and they still will not get into one row of seats. They can't. They're not capable of it.
