主　　题：coherent control spin tunneling spin-orbit coupling triple well 

摘      要：We investigate the coherent control of spin tunneling for a spin–orbit(SO)coupled boson trapped in a driven triple *** the high-frequency limit,the quasienergies of the system are obtained analytically and the fine energy band structures are *** regulating the driving parameters,we reveal that the directed spin-flipping or spin-conserving tunneling of an SOcoupled boson occurs along different pathways and in different *** analytical results are demonstrated by numerical simulations and good agreements are ***,an interesting scheme of quantum spin tunneling switch with or without spin-flipping is *** results may have potential applications in the design of spintronic devices.
