DESCRIPTION:Prof. Donhee Ham\, Harvard\nWhile electromagnetic resonance is
  used broadly in integrated \ncircuits works\, the plasmonic resonance\, t
 he collective motions of \nelectrons\, has not been used as much in electr
 onics\, as they typically \noccur at optical frequencies with bulk conduct
 ors\, with a notable \nexample being surface plasmons. When electrons are 
 confined into low \ndimensions (e.g.\, 1D with carbon nanotubes)\, they ca
 n occur at much \nlower frequencies in the electronics regime. In this wor
 k\, I will \npresent our experimental study of collective behaviors of int
 eracting \nelectrons in low dimensions via their coupling with electromagn
 etic \nfields and quantum effects. Due to the low dimensional plasmons’ 
 unique \ndynamical and quantum-mechanical properties\, they can bring sign
 ificant \nadvantages to electronics\, aid in the study of the quantum syst
 ems \nthrough enhanced interactions with matters with fine quantum splitti
 ngs\, \nand can provide a frequency-domain means of studying electron-elec
 tron \ninteractions in one dimension\, which are of significance in conden
 sed \nmatter physics and many-body physics (e.g.\, Luttinger-Tomonaga liqu
 id \ntheory). Our recent results highlight some of these significant benef
 its \nof the low-dimensional plasmons.
