Quantum transport in the presence of engineered quantum fields (A03)

• Subject Area: Theoretical Condensed Matter Physics
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 425217212

We examine quantum field-matter interaction in nonequilibrium conditions, focusing on electronic transport influenced by various bosonic quantum fields. Previously we revealed quantum oscillations in transport and nonlinear renormalization of exchange parameters. In future we will investigate ultrafast coherent quantum transport with Coulomb interactions, alongside understanding entanglement using a hybrid generalized Wigner functional. Additionally, we will aim on magnon quantum properties with magnon squeezing and investigate entanglement persistence in strongly nonlinear regimes. We also explore spin transport at the atomic scale.
