Generation of heat pulses in mesoscopic conductors using light fields
Pedro Portugal, Riku Tuovinen, Christian Flindt
We propose to generate heat pulses in mesoscopic conductors using light fields. In contrast to single-electron excitations such as levitons, which are created by accurate voltage d…
Atomically Reconfigurable Single-Molecule Optoelectronics
Atif Ghafoor, Santeri Neuvonen, Thinh Tran +6
Deterministic control of excitonic properties is key to advancing nanoscale optoelectronic and quantum technologies and to understanding diverse physical, optical, chemical, and bi…
Current cross-correlation spectroscopy of Majorana bound states
Michael Ridley, Eliahu Cohen, Christian Flindt +1
The clock speed of topological quantum computers based on Majorana zero mode (MZM)-supporting nanoscale devices is limited by the time taken for electrons to traverse the device. W…
Stability bounds for the generalized Kadanoff-Baym ansatz in the Holstein dimer
O. Moreno Segura, Y. Pavlyukh, R. Tuovinen
Predicting real-time dynamics in correlated systems is demanding: exact two-time Green's function methods are accurate but often too costly, while the Generalized Kadanoff-Baym Ans…
Thermoelectric energy conversion in molecular junctions out of equilibrium
R. Tuovinen, Y. Pavlyukh
Understanding time-resolved quantum transport is crucial for developing next-generation quantum technologies, particularly in nano- and molecular junctions subjected to time-depend…
Time-linear quantum transport simulations with correlated nonequilibrium Green's functions
R. Tuovinen, Y. Pavlyukh, E. Perfetto +1
We present a time-linear scaling method to simulate open and correlated quantum systems out of equilibrium. The method inherits from many-body perturbation theory the possibility t…
