Energy Focusing also plays a role in turbulence where intermittent structure can appear see:

      • "Imaging of Intermittency in Ripple-Wave Turbulence " with William Wright, R. Budakian, and D. Pine; Science 278, 1609 (1997)

  • Energy focusing also plays a role in everyday friction where small normal loads are concentrated to megabar pressures at the interfacial bonds which we propose are important to friction:

      • "Real Time Imaging of Two-Dimensional Charge on Dielectric Surfaces: with R. Budakian; Rev. Sci.Instr, 71, 444 (2000).
      • "Correlation Between Charge Transfer and Stick-Slip Friction at a Metal Insulator Interface" with R. Budakian; Phys. Rev. Lett. 85, 1000 (2000)
      • "Time Scales for Cold Welding and the Origins of Stick-Slip Friction," with R. Budakian; Physical Review; B65, 235429-1 –5 (2002): News story Nature Materials: - http://www.nature.com/nsu/020311-11.html
