We calculate perturbatively the tunneling decay rate $\ensuremath{\Gamma}$ of the metastable phase in the quantum $d=1$ Ising model in a skew magnetic field near the coexistence line $0l{h}_{x}l1, {h}_{z}\ensuremath{\rightarrow}\ensuremath{-}0$ at $T=0.$ It is shown that $\ensuremath{\Gamma}$ oscillates in the magnetic field ${h}_{z}$ due to discreteness of the excitation energy spectrum. After mapping of the obtained results onto the extreme anisotropic $d=2$ Ising model at $Tl{T}_{c},$ we… CONTINUE READING
