Disorder driven maximum in the magnetoresistance of spin polaron systems
Tanmoy Mondal, Pinaki Majumdar
Ferromagnetic polarons are self trapped states of an electron in a locally spin polarised environment. They occur close to the magnetic in low carrier density local moment ma…
Crossover from self-trapped bound states to perturbative scattering in the Heisenberg-Kondo lattice model
Tanmoy Mondal, Pinaki Majumdar
We map out the complete transport phase diagram of the ferromagnetic Heisenberg-Kondo lattice model in two dimensions. The model involves tight-binding electrons with hopping ,…
Disorder enhanced ferromagnetic polaron formation -- and the test case of Europium Oxide
Tanmoy Mondal, Pinaki Majumdar
Europium Oxide (EuO), a low carrier density local moment ferromagnet, shows a wide variety of transport behaviour depending on preparative conditions. Some samples have a moderate…
Dynamics in the nonequilibrium energy landscape of a frustrated Mott insulator
Sankha Subhra Bakshi, Tanmoy Mondal, Pinaki Majumdar
In a Mott insulator, a laser pulse with frequency tuned to the gap scale can create a holon-doublon plasma, suppressing the magnetic moment and destroying magnetic ord…
