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…
Heat, work, and fluctuations in a driven quantum resonator
Riya Baruah, Pedro Portugal, Jun-Zhe Chen +2
A central building block of a heat engine is the working fluid, which mediates the conversion of heat into work. In nanoscale heat engines, the working fluid can be a quantum syste…
Negative currents in Fabry-Pérot cavities are caused by interfering paths
Mrinmoyee Saha, Luca Horray, Pedro Portugal +1
It has been predicted that the time-dependent current in a Fabry-Pérot cavity can turn negative even if the applied voltage pulses are always positive. It has also been suggested t…
Fast, Accurate, and Local Temperature Control Using Qubits
Riya Baruah, Pedro Portugal, Joachim Wabnig +1
Many quantum technologies, including quantum computers, quantum heat engines, and quantum sensors, rely on operating conditions in the subkelvin regime. It is therefore desirable t…
Photon counting statistics in Gaussian bosonic networks
Kalle S. U. Kansanen, Pedro Portugal, Christian Flindt +1
The statistics of transmitted photons in microwave cavities play a foundational role in microwave quantum optics and its technological applications. By utilizing quantum mechanical…
Heat Pulses in Electron Quantum Optics
Pedro Portugal, Fredrik Brange, Christian Flindt
Electron quantum optics aims to realize ideas from the quantum theory of light with the role of photons being played by charge pulses in electronic conductors. Experimentally, the…
Photon emission statistics of a driven microwave cavity
Pedro Portugal, Fredrik Brange, Kalle S. U. Kansanen +2
Recent experimental advances have made it possible to detect individual quantum jumps in open quantum systems, such as the tunneling of single electrons in nanoscale conductors or…
Effective temperature pulses in open quantum systems
Pedro Portugal, Fredrik Brange, Christian Flindt
Controlling the temperature of nano-scale quantum systems is becoming increasingly important in the efforts to develop thermal devices such as quantum heat valves, heat engines, an…
Heat transport in a two-level system driven by a time-dependent temperature
Pedro Portugal, Christian Flindt, Nicola Lo Gullo
The field of thermotronics aims to develop thermal circuits that operate with temperature biases and heat currents just as how electronic circuits are based on voltages and electri…
