“…Transition dipole matrix elements * s.l.cornish@durham.ac.uk are fundamental properties of atoms as well as being crucial parameters for determining, for example, the blackbody radiation shift of atoms which is often a limiting systematic uncertainty in atomic clocks [27]. A number of discrepancies between experimental results and between theory and experiment have been pointed out in the literature [28][29][30][31] recently, giving particular importance to further benchmark tests.…”

“…In general, the polarizability is therefore composed into scalar, vector, and tensor polarizabilities where the scalar polarizability is the polarizability when averaging over all m F levels. State-specific potentials can be used to engineer multi-particle entanglement [34], spatiotemporal control of intraspecies interactions [35], and state-selective manipulation of quantum states [31,36].…”

“…Tune-out wavelengths have been experimentally measured both directly and indirectly. Direct measurements are made by performing polarizability measurements around the tune-out wavelength, with experimental techniques, including atom diffraction [25], parameteric heating [31], and atom interferometry [37]. Indirect measurements can be made by inferring tune-out wavelengths from measurements of state lifetimes, but can be limited by knowledge of branching ratios [25].…”

“…Indirect measurements can be made by inferring tune-out wavelengths from measurements of state lifetimes, but can be limited by knowledge of branching ratios [25]. Previous experiments have directly measured tuneout wavelengths, using linearly polarized light, for different alkali-metal atoms, including Li [38,39], K [26,40], and Rb [25,33,37,41], as well as for other atomic species, including He [42], Sr [31], and Dy [43] and also for ground-state NaK molecules [44]. However, despite many theoretical studies of 133 Cs polarizability [45][46][47][48], so far no measurements of 133 Cs scalar tune-out wavelength have been performed.…”

We perform a measurement of the tune-out wavelength, λ 0 , between the D 1 , 6 2 S 1/2 → 6 2 P 1/2 , and D 2 , 6 2 S 1/2 → 6 2 P 3/2 , transitions for 133 Cs in the ground hyperfine state (F = 3, m F = +3). At λ 0 , the frequencydependent scalar polarizability is zero leading to a zero scalar ac Stark shift. We measure the polarizability as a function of wavelength using Kapitza-Dirac scattering of a 133 Cs Bose-Einstein condensate in a one-dimensional optical lattice, and determine the tune-out wavelength to be λ 0 = 880.21790( 40) stat (8) sys nm. From this measurement we determine the ratio of reduced matrix elements to be 1.9808(2). This represents an improvement of a factor of 10 over previous results derived from excited-state lifetime measurements. We use the present measurement as a benchmark test of high-precision theory.

“…As there are several groups in the world performing experiments with strontium, mostly for the purpose of metrology and quantum simulation [143,153,[181][182][183][184][185][186], our group has one of the highest flux of atoms in our apparatus [1]. With only laser-cooling we get down to ≈ 3 µK with more than 15 million atoms.…”

Experimental observation of Zitterbewegung is considered a holy grail of the modern physics since its debut in 1930 by Schrödinger. In this thesis we describe the first experimental observation of this effect in a two-dimensional ultracold atomic wave packet. In addition to that, we have also revealed the anisotropic of nature of Zitterbewegung, in the presence of non-Abelian Gauge field.To all my teachers who have prepared me for this adventurous journey of a lifelong student List of Figures2.1 A typical way to realize the Abelian gauge field via Raman scheme. Here L 1 and L 2 each addresses the transition |↑ → |e and |↓ → |e , respectively. The two-photon detuning is δ while both lasers L 1,2 are far off-detuned from the excited-state |e . . . . . . . . . . . . . . . . 2.2 Dispersion relation of a one-dimensional spin-orbit coupled system given by the Hamiltonian in Eq. 2.4. The left panel describes two shifted parabolas when the Raman coupling Ω and two-photondetuning δ are zero. In the middle panel, a non zero Raman coupling opens the gap at zero momentum since this term behaves like a Zeeman term in the Hamiltonian given by Eq. 2.4. The right panel shows the effect of non-zero two-photon detuning δ. The dispersion relation becomes tilted as δ acts as a constant shift in momentum in Eq.
