Observation and investigation of narrow optical transitions of 167Er3+ ions in femtosecond laser printed waveguides in 7LiYF4 crystal
M. M. Minnegaliev, I. V. Dyakonov, K. I. Gerasimov +5
We produced optical waveguides in the 167Er3+ :7LiYF4 crystal with diameters ranging from 30 to 100 mkm by using the depressed-cladding approach with femtosecond laser. These waveg…
On sensitivity limitations of a dichromatic optical detection of a classical mechanical force
Sergey P. Vyatchanin, Andrey B. Matsko
We apply the strategy of the back action evading measurement of a quadrature component of mechanical motion of a test mass to detection of a classical force acting on the mass (Sci…
Light scattering from an atomic gas under conditions of quantum degeneracy
V. M. Porozova, L. V. Gerasimov, M. D. Havey +1
We consider a quantum theory of elastic light scattering from a macroscopic atomic sample existing in the Bose-Einstein condensate (BEC) phase. The dynamics of the optical excitati…
Non-Gaussianity of multiple photon subtracted thermal states in terms of compound-Poisson photon number distribution parameters: theory and experiment
G. V. Avosopiants, K. G. Katamadze, Yu. I. Bogdanov +1
The multiphoton-subtracted thermal states are an interesting example of quantum states of light which are both classical and non-Gaussian. All the properties of such states can be…
Light Scattering From an Atomic Array Trapped Near a One-Dimensional Nanoscale Waveguide: a Microscopic Approach
V. A. Pivovarov, A. S. Sheremet, L. V. Gerasimov +4
The coupling of atomic arrays and one-dimensional subwavelength waveguides gives rise to in- teresting photon transport properties, such as recent experimental demonstrations of la…
Overcoming the SQL in gravitational wave detectors using spin systems with negative effective mass
Farid Khalili, Eugene S. Polzik
Quantum back action (QBA) of a measurement limits the precision of observation of the motion of a free mass. This profound effect dabbed the "Heisenberg microscope" in the early da…
