Superfluid Helium Drops Levitated in High Vacuum

Autor: Brown, C. D., Wang, Y., Namazi, M., Harris, G. I., Uysal, M. T., Harris, J. G. E.

We demonstrate the trapping of millimeter-scale superfluid Helium drops in high vacuum. The drops are sufficiently isolated that they remain trapped indefinitely, cool by evaporation to 330 mK, and exhibit mechanical damping that is limited by intern

Quantum optomechanics in a liquid

Autor: Shkarin, A. B., Kashkanova, A. D., Brown, C. D., Garcia, S., Ott, K., Reichel, J., Harris, J. G. E.

Publikováno v: Phys. Rev. Lett. 122, 153601 (2019)

Optomechanical systems provide a means for studying and controlling quantum effects in the motion of macroscopic objects. To date, quantum optomechanical effects have been studied in objects made from solids and gases. Here we describe measurements o

Cavity Optomechanics in a Levitated Helium Drop

Autor: Childress, L., Schmidt, M. P., Kashkanova, A. D., Brown, C. D., Harris, G. I., Aiello, A., Marquardt, F., Harris, J. G. E.

Publikováno v: Phys. Rev. A 96, 063842 (2017)

We describe a proposal for a new type of optomechanical system based on a drop of liquid helium that is magnetically levitated in vacuum. In the proposed device, the drop would serve three roles: its optical whispering gallery modes would provide the

Photothermal optomechanics in superfluid helium coupled to a fiber-based cavity

Autor: Kashkanova, A. D., Shkarin, A. B., Brown, C. D., Flowers-Jacobs, N. E., Childress, L., Hoch, S. W., Hohmann, L., Ott, K., Reichel, J., Harris, J. G. E.

Presented in this paper are measurements of an optomechanical device in which various acoustic modes of a sample of superfluid helium couple to a fiber-based optical cavity. In contrast with recent work on the paraxial acoustic mode confined by the c

Superfluid Brillouin Optomechanics

Autor: Kashkanova, A. D., Shkarin, A. B., Brown, C. D., Flowers-Jacobs, N. E., Childress, L., Hoch, S. W., Hohmann, L., Ott, K., Reichel, J., Harris, J. G. E.

Optomechanical systems couple an electromagnetic cavity to a mechanical resonator which is typically formed from a solid object. The range of phenomena accessible to these systems depends on the properties of the mechanical resonator and on the manne
