Spontaneous magnetization of quantum spin model in joint presence of quenched and annealed disorder
Anindita Bera, Debraj Rakshit, Aditi Sen De +1
We investigate equilibrium statistical properties of the quantum XY spin-1/2 model in an external magnetic field when the interaction and field parts are subjected to quenched or/a…
Order-from-disorder and critical scalings of spontaneous magnetization in random-field quantum spin systems
Anindita Bera, Debraj Rakshit, Maciej Lewenstein +3
We investigate the effect of a unidirectional quenched random field on the anisotropic quantum spin-1/2 model, which magnetizes spontaneously in the absence of the random fiel…
Classical spin models with broken symmetry: Random Field Induced Order and Persistence of spontaneous magnetization in presence of a random field
Anindita Bera, Debraj Rakshit, Maciej Lewenstein +3
We consider classical spin models of two- and three-dimensional spins with continuous symmetry and investigate the effect of a symmetry-breaking unidirectional quenched disorder on…
