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…
Constructive Interference Between Disordered Couplings Enhances Multiparty Entanglement in Quantum Heisenberg Spin Glass Models
Utkarsh Mishra, Debraj Rakshit, R. Prabhu +2
Disordered systems form one of the centrestages of research in many body sciences and lead to a plethora of interesting phenomena and applications. A paradigmatic disordered system…
Beating no-go theorems by engineering defects in quantum spin models
Debasis Sadhukhan, Sudipto Singha Roy, Debraj Rakshit +2
There exist diverse no-go theorems, ranging from no-cloning to monogamies of quantum correlations and Bell inequality violations, which restrict the processing of information in th…
