Spatial instability of a homogeneous superconductor after an interaction quench
Medha Roy Choudhury, Sankha Subhra Bakshi, Pinaki Majumdar +1
We investigate the quantum dynamics of a conventional superconductor, described by the attrac- tive Hubbard model, driven far from equilibrium by quenching the Hubbard attraction.…
The Interplay of Thermal Melting and Pump Driven Melting of Charge Order: A Two-Temperature Study of the Holstein Model
Debraj Bose, Sankha Subhra Bakshi, Pinaki Majumdar
Charge order driven by electron-phonon coupling is well understood at equilibrium but pump-probe experiments raise a new question: how does this order melt and recover after strong…
Electron and phonon spectrum in a metallic nanohybrid
Debraj Bose, Saheli Sarkar, Pinaki Majumdar
Recent experiments on metallic nanohybrids have revealed unusually strong electron-phonon effects emerging from nanoscale interfaces, despite the weak coupling character of the con…
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…
Enormous enhancement of resistivity in nanostructured electron-phonon systems
Debraj Bose, Sankha Subhra Bakshi, Pinaki Majumdar
Recent experiments on nanoclusters of silver (Ag) embedded in a gold (Au) matrix reveal a huge increase in both the zero temperature resistivity and the coefficient of the `` li…
Tunneling maps, non-monotonic resistivity, and non Drude optics in EuB
Tanmoy Mondal, Pinaki Majumdar
For several decades the low carrier density local moment magnet EuB has been considered a candidate material for ferromagnetic polarons. There is however no consistent explanat…
Distinct charge and spin recovery dynamics in a photo-excited Mott insulator
Sankha Subhra Bakshi, Pinaki Majumdar
Pump-probe response of the spin-orbit coupled Mott insulator SrIrO reveals a rapid creation of low energy optical weight and suppression of three dimensional magnetic order…
