Multimode phononic correlations in a nondegenerate parametric amplifier
S. Chakram, Y. S. Patil, M. Vengalattore
We describe the realization of multimode phononic correlations that arise from nonlinear interactions in a mechanical nondegenerate parametric amplifier. The nature of these correl…
Quantum Control by Imaging : The Zeno effect in an ultracold lattice gas
Y. S. Patil, S. Chakram, M. Vengalattore
We demonstrate the control of quantum tunneling in an ultracold lattice gas by the measurement backaction imposed by an imaging process. A {\em in situ} imaging technique is used t…
Thermomechanical two-mode squeezing in an ultrahigh membrane resonator
Y. S. Patil, S. Chakram, L. Chang +1
We realize a nondegenerate parametric amplifier in an ultrahigh mechanical membrane resonator and demonstrate two-mode thermomechanical noise squeezing. Our measurements are ac…
Nondestructive imaging of an ultracold lattice gas
Y. S. Patil, L. M. Aycock, S. Chakram +1
We demonstrate the nondestructive imaging of a lattice gas of ultracold bosons. Atomic fluorescence is induced in the simultaneous presence of degenerate Raman sideband cooling. Th…
