DESCRIPTION:Phononic frequency combs (PFC) are the mechanical analogues of 
 celebrated photonic frequency combs. These represent a newly documented ph
 ysical phenomenon in the well-researched physical domain of mechanical res
 onators [1]. The emergence of PFC is mediated by nonlinear modal coupling.
  Through a series of experiments using micromechanical resonators\, variou
 s physical features of PFC have been identified. These include drive param
 eters for comb operation\, hysteresis for comb spectrum tailoring and nonl
 inear sensitivity to physical perturbations. My talk will describe the phy
 sics of PFC and will emphasize how these combs could be foundational to th
 e fields of materials science\, molecular science and chemical science. In
  that respect\, I will present our first conceptual demonstrations of mate
 rial combs\, molecular combs and chemical combs respectively. I will also 
 showcase our recent demonstrations of broadband PFC using optical tweezers
  [2] and phonon lasers [3]. The future work will be focused on the applica
 tions of PFC in sensing\, communications and quantum information science.\

 ated photonic frequency combs. These represent a newly documented physical
  phenomenon in the well-researched physical domain of mechanical resonator
 s [1]. The emergence of PFC is mediated by nonlinear modal coupling. Throu
 gh a series of experiments using micromechanical resonators\, various phys
