The model reveals both quantum-ordered and quantum-disordered fixed points under specific field conditions.
Absence of one type of field leads to distinct behaviors dictated by the random-field Ising fixed-point.
The study utilizes strong disorder renormalisation group methods to explore low-energy properties at zero temperature.
Disorder-induced scaling is characterized, showcasing a critical crossover at the infinite disorder fixed-point.
