Disorder-induced orbital ordering in doped manganites
Sanjeev Kumar, Arno P. Kampf
We study the effect of quenched disorder on the ordering of orbital and magnetic degrees of freedom in a two-dimensional, two-band double-exchange model for electrons coupled…

Combined Effect of Bond- and Potential-Disorder in Half-Doped Manganites
Sanjeev Kumar, Arno P. Kampf
We analyze the effects of both bond- and potential-disorder in the vicinity of a first-order metal insulator transition in a two-band model for manganites using a real-space Monte…

The Travelling Cluster Approximation for Strong Correlation Models of Lattice Fermions Coupled to Classical Fields
Sanjeev Kumar, Pinaki Majumdar
We suggest and implement a new Monte Carlo strategy for correlated models involving fermions strongly coupled to classical degrees of freedom, with accurate handling of quenched di…
