Auto-Compensation of Collisional Shift in Atomic Clocks Based on Bosonic Atoms in an Optical Lattice

We propose a new approach to suppress the influence of collisional shift and its fluctuations on the long-term stability of optical clocks based on bosonic atoms (even isotopes) in an 1D or 2D lattice. The successful implementation of our auto-compensation method, in combination with the hyper-Ramsey spectroscopic schemes, will allow considering bosons as a real alternative to fermions while achieving the highest metrological characteristics of atomic clocks.
