Quantum physics

From fundamental physics to applications by describing and observing quantum phenomena.

In nanostructured systems pronounced quantum behavior can be observed. We develop the theoretical tools to better describe few and many-body quantum systems in the presence of correlations and coherence, and we use advanced nanodevices to experimentally observe these effects. The goals are the discovery of new quantum physics and its potential future use in advanced quantum devices.

Subareas within Quantum physics

  • Transport physics
    We focus on experimental and theoretical studies of the transport physics and application aspects of nanostructures and quantum devices made from semiconductor heterostructures and nanowires, as well as emerging new materials.
  • Quantum technology
    An ability to utilize quantum resources like the superposition of states and entanglement opens completely new perspectives for technology. The research focus of both experiment and theory is on generating and controlling long-lived coherent states and entanglement in different systems on the nanoscale.
  • Nanothermodynamics
    We employ quantum thermodynamics to develop new paradigms for energy conversion and quantum devices at the nanoscale, where thermal and quantum fluctuations may conspire to profoundly alter the physical properties. We set focus on interacting few- or many-particle quantum systems where the effects of quantum correlations, fluctuation statistics and quantum coherence lead to fundamentally new physics when reaching truly microscopic sizes far from the thermodynamic limit.
  • Quantum optics 
    Quantum optics describes how individual quanta of light, the photons, interact with atoms, molecules and larger pieces of matter. We focus on studies of light interacting with nanoscale systems, in both experiment and theory. Our motivation for this is to create and study hybridized quantum states between electrons and photons. We also aim for example to increase the coherence of these states and their interaction strength to build electro-optical systems, devices and sensors.
