The charge density fluctuations and the Shrinking Fermi Liquid scenario for strange metallicity in cuprates
Sergio Caprara, Sauri Bhattacharyya, Carlo Di Castro +3
We interpret the strange metal (SM) properties of slightly overdoped cuprates in terms of the recently proposed Shrinking Fermi Liquid theory. This is based on the pervading presen…
Metallic transport of hard core bosons
Sauri Bhattacharyya, Ayush De, Snir Gazit +1
Conductivities and Hall coefficients of two dimensional hard core bosons are calculated using the thermodynamic expansions of Kubo formulas. At temperatures above the superfluid tr…
Hall map and breakdown of Fermi liquid theory in the vicinity of a Mott insulator
Ilia Khait, Sauri Bhattacharyya, Abhisek Samanta +1
The Hall coefficient exhibits anomalous behavior in lightly doped Mott insulators. For strongly interacting electrons its computation has been challenged by analytical and numerica…
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…
Modeling dynamical phonon fluctuations across the magnetically driven polaron crossover in the manganites
Sauri Bhattacharyya, Saurabh Pradhan, Pinaki Majumdar
We investigate the dynamical structure factor associated with lattice fluctuations in a model that approximates the manganites. It involves electrons strongly coupled to core spins…
Thermal dynamics of lattice modes near a polaronic crossover: from the dilute polaron limit to a charge ordered state
Sauri Bhattacharyya, Saurabh Pradhan, Pinaki Majumdar
We provide a comprehensive solution to the lattice dynamics problem in the two dimensional Holstein model at finite electron density and finite temperature. We work in the physical…
