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…

Excitations across the equilibrium and photoinduced `hidden' states of magnetoresistive manganites
Shiyu Fan, Feng Jin, Taehun Kim +16
"Hidden" phases, generated using ultrafast laser pulses (few hundred femtoseconds), with properties distinct from thermodynamic equilibrium, are appealing for technologies because…
