Fragmentation and Emergent Integrable Transport in the Weakly Tilted Ising Chain
Fragmentation and Emergent Integrable Transport in the Weakly Tilted Ising Chain
We investigate emergent quantum dynamics of the tilted Ising chain in the regime of a weak transverse field. Within the leading order perturbation theory, the Hilbert space is fragmented into exponentially many decoupled sectors. We find that the sector made of isolated magnons is integrable with dynamics being governed by …
