In your opinion, what are the main challenges for future condensed matter physics? What type of material systems are more desirable to discover? Which quantum properties are the most interesting to demonstrate for future devices working at room temperature and ambient pressure (besides...
Hi Dr_Nate,
As far as I know, LO phonons are responsible for the Frohlich interaction that mediates the formation of large polarons in many materials. LO phonons also play an important role in the formation of Cooper pairs in BCS superconductivity. TA and LA phonons play an important role in...
Phonons can be acoustic or optical in their character and transverse or longitudinal in their polarization. While the importance of longitudinal acoustic (LA), transverse acoustic (TA), and longitudinal optical (LO) phonons is clear to me for the emergence of different quantum phenomena and for...
