Dear Friends,
On Friday, May 16, there will be an ITAMP topical lunch discussion.
Time: 12:00-1:30
Location: B-106 @ Center for Astrophysics (60 Garden Street)
Directions: after entering the lobby of the CfA, turn right to enter the
hallway of the B building. In the hallway, turn right again, and B-106 is
there.
As always pizza will be served.
Speaker: Prof. Kurt Jacobs (U Mass Boston)
Title: Modulated Electromechanics: Large Enhancements of Nonlinearities
Abstract:
It is well-known that the nonlinear coupling between a mechanical
oscillator and a superconducting oscillator or optical cavity can be used
to generate a Kerr-nonlinearity for the cavity mode. We show that the
strength of this Kerr-nonlinearity, as well as the effect of the
photon-pressure force can be enormously increased by modulating the
strength of the nonlinear coupling. We present an electromechanical circuit
in which this enhancement can be readily realized.
Looking forward to seeing you there,
Misha Lemeshko
