• Abstract summary: We present the development of an electrometer, leveraging on the spectroscopy of an optically-active spin defect embedded in a solid-state material with a non-linear Stark response. We successfully localize charge traps, quantify their impact on transport dynamics and noise generation, analyze relevant material properties, and develop strategies for material optimization.

• Abstract: The detection of individual charges plays a crucial role in fundamental material science and the advancement of classical and quantum high-performance technologies that operate with low noise. However, resolving charges at the lattice scale in a time-resolved manner has not been achieved so far. Here, we present the development of an electrometer, leveraging on the spectroscopy of an optically-active spin defect embedded in a solid-state material with a non-linear Stark response. By applying our approach to diamond, a widely used platform for quantum technology applications, we successfully localize charge traps, quantify their impact on transport dynamics and noise generation, analyze relevant material properties, and develop strategies for material optimization.

  We study the transport properties of materials characterized by strong electron-phonon coupling, in contact with a dissipative environment. We combine the non-Markovian hierarchy of pure states method and the Markovian quantum jumps method with the newly introduced purified density-matrix renormalization group. Surprisingly, our results show that in the metallic phase dissipation localizes the bipolarons, which is reminiscent of an indirect quantum Zeno effect.
