Yu-Shiba-Rusinov states of single magnetic molecule in an superconductor
Saurabh Pradhan, Jonas Fransson
We use the numerical renormalization group theory to investigate the Yu-Shiba-Rusinov (YSR) bound state properties of single magnetic molecules placed in an s-wave superconducting…
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…
Identification of topological superconductivity in magnetic impurity systems using bulk spin-polarization
Mahdi Mashkoori, Saurabh Pradhan, Kristofer Björnson +2
Magnetic impurities on the surface of spin-orbit coupled but otherwise conventional superconductors provide a promising way to engineer topological superconductors with Majorana bo…
Time-dependent potential impurity in topological insulator
Saurabh Pradhan, Jonas Fransson
We consider periodically driven potential impurities coupled to the surface states of a two-dimensional topological insulator. The problem is addressed by means of two models, out…
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…
