Interplay of slow charge carrier dynamics and elastic effects in correlated multi-phase systems via noise spectroscopy (B02)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 422213477

The project investigates the slow dynamics of correlated charge carriers arising from their coupling to the elastic properties of the underlying crystal lattice in organic charge-transfer salts and intermetallic AT2X2 compounds. To this end, fluctuation spectroscopy – also under pressure – will be performed. By measuring the low-frequency (mHz – kHz) resistance or conductance noise, we gain information about the impact of critical modes, geometric frustration and disorder on the in- and out-of-equilibrium dynamics of ordered states.
