Nonequilibrium dynamics of suppression, revival, and loss of charge order in a laser pumped electron-phonon system
Sankha Subhra Bakshi, Debraj Bose, Arijit Dutta +1
An electron-phonon system at commensurate filling often displays charge order (CO) in the ground state. Such a system subject to a laser pulse shows a wide variety of behaviour. A…
Fermi arcs and pseudogap phase in a minimal microscopic model of -wave superconductivity
Dheeraj Kumar Singh, Samrat Kadge, Yunkyu Bang +1
We show conclusively that a pseudogap state can arise at , for reasonable pairing interaction strength, from order parameter fluctuations in a two dimensional minimal mode…
Nonequilibrium thermal state of a voltage-biased Mott insulator
Arijit Dutta, Pinaki Majumdar
We establish the nonequilibrium thermal phases of a voltage driven antiferromagnetic Mott insulator in three dimensions, realised at steady state under a voltage bias. Starting fro…
Dynamics of magnetic collective modes in the square and triangular lattice Mott insulators at finite temperature
Sauri Bhattacharyya, Pinaki Majumdar
We study the equilibrium dynamics of magnetic moments in the Mott insulating phase of the Hubbard model on the square and triangular lattice. We rewrite the Hubbard interaction in…
Strongly anharmonic collective modes in a coupled electron-phonon-spin problem
Sauri Bhattacharyya, Sankha Subhra Bakshi, Saurabh Pradhan +1
We solve for the finite temperature collective mode dynamics in the Holstein-double exchange problem, using coupled Langevin equations for the phonon and spin variables. We present…
A Langevin approach to lattice dynamics in a charge ordered polaronic system
Sauri Bhattacharyya, Sankha Subhra Bakshi, Samrat Kadge +1
We use a Langevin approach to treat the finite temperature dynamics of displacement variables in the half-filled spinless Holstein model. Working in the adiabatic regime we exploit…
