Many-body spin rotation by adiabatic passage in spin-1/2 XXZ chains of ultracold atoms

Abstract Quantum many-body phases offer unique properties and emergent phenomena, making them an active area of research. A promising approach for their experimental realization in model systems is to adiabatically follow the ground state a quantum Hamiltonian from product isolated particles one that strongly-correlated. Such protocols are relevant also more broadly coherent annealing adiabatic computing. Here we explore such protocol system ultracold atoms optical lattice. fully magnetized connected correlated zero-magnetization (an xy -ferromagnet) by spin rotation, realized sweeping detuning power microwave field. The efficiency characterized applying reverse sweep with variable relative phase. We restore up 50 % original magnetization independent phase, evidence formation correlations. limited gap final state, which inversely proportional size, technical noise. Our theoretical studies highlight potential challenges preparation prepare eigenstates Hamiltonians.
