The coupling of these quasiparticles with Mie resonances leads to the tunability of TMDC nanoresonators. Leonid Keldysh predicted that, at low temperature and high density, a gas of these quasiparticles undergoes a Mott transition to form a strongly-correlated liquid. When the components of these quasiparticles are spatially confined to separate layers, they are called “indirect” (-5[1])and are ideal for studying (15[1])BECs. (-5[1])The energy levels of these quasiparticles (15[1])are given by the (*) Rydberg constant divided by n-squared, since they behave like hydrogen atoms. Smaller examples of these quasiparticles are named for Yakov Frenkel, (10[1]-5[1])while larger ones are named for Wannier and Mott. These Coulombically-attracted quasiparticles have energy just below the band gap. (-5[2])For 10 points, name these bound states consisting of an electron (10[1])and (10[1])a hole. ■END■ (10[2]0[1])
