Anomalous temperature dependence of polaron mobility in a nonlinear double-well potential: unbiased X-propagator approach
Stefano Ragni, Osor S. Barišić, Naoto Nagaosa +1
We develop an unbiased X-propagator method for calculating finite-temperature optical conductivity and dc mobility for arbitrary nonlinear electron-phonon interaction. W…
Polaron formation as the vertex function problem: From Dyck's paths to self-energy Feynman diagrams
Tomislav Miškić, Juraj Krsnik, Stefano Ragni +2
We present an iterative method for generating the complete set of self-energy Feynman diagrams at arbitrary order for the single-polaron problem with arbitrary linear coupling to t…
Superconductivity in 2D systems enhanced by nonadiabatic phonon-production effects
Juraj Krsnik, Dino Novko, Osor Slaven Barišić
We investigate the dynamical effects of electron-phonon coupling (EPC) on the superconducting properties of two-dimensional (2D) systems, calculating the Eliashberg function in ter…
Transport properties and doping evolution of the Fermi surface in cuprates
Benjamin Klebel-Knobloch, Wojciech Tabis, Mateusz A. Gala +3
Measured transport properties of three representative cuprates are reproduced within the paradigm of two electron subsystems, itinerant and localized. The localized subsystem evolv…
Characterization of two electronic subsystems in cuprates through optical conductivity
C. M. N. Kumar, Ana Akrap, Chris C. Homes +6
Understanding the physical properties of unconventional superconductors as well as of other correlated materials presents a formidable challenge. Their unusual evolution with dopin…
Importance of coupling strength in shaping electron energy loss and phonon spectra of phonon-plasmon systems
J. Krsnik, O. S. Barišić
A systematic analysis of phonon-plasmon coupled excitations in three-dimensional (3D) polar systems is provided through the prism of both raw and integrated electron energy loss sp…
