Miles Blencowe
Miles Blencowe received his B.Sc. (1986) and Ph.D. (1989) degrees in theoretical physics at Imperial College. He subsequently held postdoctoral fellowships at the University of Cambridge (1989-1991), the University of Chicago (1991-1993), and the University of British Columbia (1993-1994). Following a senior research associate position at Imperial College (1994-1999), he moved to Dartmouth College where he is currently an associate professor in the Department of Physics and Astronomy. His research interests lie in the areas of mesoscopic physics, quantum information theory applied to solid-state systems, and non-equilibrium statistical mechanics.
How to silence a one-ton bell
The longitudinal ringing mode of a metal bar resonator weighing approximately one metric ton has been cooled to submillikelvin temperatures with the use of active amplifier feedback. Further improvements may allow researchers to approach the quantum limit for cooling macroscopic objects. Read More »
