  • Families of quasilocal conservation laws and quantum spin transport
    Prosen, Tomaž, 1970- ; Ilievski, Enej
    For fundamental integrable quantum chains with deformed symmetries we outline a general procedure for defining a continuous family of quasilocal operators whose time derivative is supported near the ... two boundary sites only. The program is implemented for a spin 1/2 XXZ chain, resulting in improved rigorous estimates for the high temperature spin Drude weight.
