Lattice dynamic phase shift
WebThen, we consider a deep optical lattice loaded with ultracold dipolar bosons. In order to describe this system, we introduce a novel atom-dimer extended Bose-Hubbard model, which is the minimal model correctly accounting for the DIR. We analyze the impact of the DIR on the phase diagram at T=0 by exact diagonalization of a small-sized system. Web7 sep. 2024 · However, lattice dynamic, offers two different ways of finding the dispersion relation within the lattice\(^{[6]}\). Quantum-mechanical approach: Quantum-mechanical approach can be used to obtain phonon's dispersion relation. In order to do so, the solution to the Schrödinger equation for the lattice vibrations must be solved.

Web28 mrt. 2024 · The most stable and most abundant isotopes are 32 S and 34 S. In our work, we focused on the MLs composed of natural sulfur, isotopically pure 32 S and 34 S, and a 1:1 ratio of 32 S and 34 S. We carried out an extensive investigation of the lattice dynamics, reformed due to the isotopic abundance. Web29 jul. 2024 · GeCo 2 O 4 is a unique system in the family of cobalt spinels A Co 2 O 4 (A = Sn, Ti, Ru, Mn, Al, Zn, Fe, etc.) in which magnetic Co ions stabilize on the pyrochlore lattice exhibiting a large degree of orbital frustration. Due to the complexity of the low-temperature antiferromagnetic (AFM) ordering and long-range magnetic exchange interactions, the …
WebThe skyrmion lattice (SkL) phase is evident in the y=0 and 8 materials through an enhanced response of the muon-spin relaxation to the emergent dynamics that accompany the SkL.
