timo Posted August 22, 2016 Share Posted August 22, 2016 I just saw you wrote phonon, not photon - I first misread that. It that case I replace my previous "from experiments" with "they are completely different by concept". Neutrinos are particles that can exist in vacuum. Phonons are a concept to describe the state of a crystal. Link to comment Share on other sites More sharing options...
granpa Posted August 22, 2016 Author Share Posted August 22, 2016 Phonons have particle like properties too Link to comment Share on other sites More sharing options...
swansont Posted August 22, 2016 Share Posted August 22, 2016 Phonons are bosons, neutrinos are fermions and only interact via the weak force. 1 Link to comment Share on other sites More sharing options...
granpa Posted August 22, 2016 Author Share Posted August 22, 2016 Whereas the elementary particles that make up matter (i.e. leptons and quarks) are fermions, the elementary bosons are force carriers that function as the 'glue' holding matter together. So what is the force mediated by phonons? Link to comment Share on other sites More sharing options...

So what is the force mediated by phonons? Phonons are not fundamental/elementary particles. They are not force carriers. Link to comment Share on other sites More sharing options...
Strange Posted August 22, 2016 Share Posted August 22, 2016 What does a phonon do that a neutrino can't? Not take part in beta decay. Not have mass. Not have half-integer spin. Remind me again, what characteristics did you say they have in common? Link to comment Share on other sites More sharing options...
