Stability of scar states in the two-dimensional PXP model against random disorder

چکیده
Recently a class of quantum systems exhibiting weak ergodicity breaking has attracted much attention. These feature special band eigenstates called many-body scar states in the energy spectrum. In this work we study fate two-dimensional lattice against random disorders. We show that both square and honeycomb can persist up to finite disorder strength, before eventually being erased by disorder. further localization properties system presence even stronger disorders whether full transition occurs depends on type introduce. Our thus reveals fascinating interplay between scarring system.

The random-bond Ising model on the square lattice has several disordered critical points, depending on the probability distribution of the bonds. There are a finite-temperature multicritical point, called Nishimori point, and a zerotemperature fixed point, for both a binary distribution where the coupling constants take the values ±J and a Gaussian disorder distribution. Inclusion of dilution i...
متن کاملDisorder, order, and domain wall roughening in the two-dimensional random field Ising model
Ground states and domain walls are investigated with exact combinatorial optimization in two-dimensional random field Ising magnets. The ground states break into domains above a length scale that depends exponentially on the random field strength squared. For weak disorder, this paramagnetic structure has remnant longrange order of the percolation type. The domain walls are super-rough in order...
