Dynamics of an itinerant spin-3 atomic dipolar gas in an optical lattice

Abstract: Arrays of ultra-cold dipolar gases loaded in optical lattices are emerging as powerful quantum simulators of the many-body physics associated with the rich interplay between long-range dipolar interactions, contact interactions, motion, and quantum statistics. In this work we report on our investigation of the quantum many-body dynamics of a large ensemble of bosonic magnetic chromium atoms with spin S = 3 in a three-dimensional lattice as a function of lattice depth. Using extensive theory and experimental co… Show more

“…In agreement with previous results [15][16][17], we find that the spin population dynamics is well captured by a semiclassical method, referred to as the generalized discrete truncated Wigner approximation (GDTWA), based on a discrete Monte Carlo sampling in phase space [18,19]. In addition, we find that spin dynamics is barely affected by the spin echo.…”

“…Practically, in the GDTWA simulation all distances smaller than r cutoff are set to be equal to r cutoff . This is partially motivated by the intuition that the contact interaction between Cr atoms under the experimental condition is very strong (∼kHz [16]) and thus prevents two atoms from being very close. Besides, since this fraction is tiny, except for small differences on the short-time scale (∼ h/18V0 ∼ 5ms, where V0 = µ 0 (gµ B ) 2 4πd 3…”

“…dTWA is recently employed to study large spin systems in which dynamical phase transitions are explored [16]. Also, the results from dTWA are found to be in good agreement with experiments using Rydberg [17][18][19][20] and dipolar atoms [21][22][23]. The Rydberg experiments explored the magnetization relaxation dynamics in a quantum spin system [17][18][19] and superradiance triggered by black-body radiation [20], in which the quantum fluctuations are accommodated in the sampling of the initial state.…”

“…The recent topics explored in experiments include thermalization dynamics of an isolated quantum system [2,3], propagation of non-local correlations [4,5], the Kibble-Zurek mechanism across quantum phase transitions [6], and the many-body localization (MBL) in a disordered optical lattice [7,8]. In recent years, technological developments in creating, controlling, and probing cold atoms or molecules with strong dipole-dipole interactions in an optical lattice [9][10][11][12][13][14][15], Rydberg gases [16][17][18][19][20][21][22][23][24][25], and trapped ions [26][27][28][29][30][31] have enabled quantum simulation of various quantum-spin systems with long-range interactions. In particular, Rydberg gases can be manipulated by means of the optical tweezer techniques, so that these offer an intriguing playground to explore novel quantum magnetism and non-equilibrium dynamics of localized spins caused by variable-range interactions.…”
