Prof. A. Hofmann's Group

Our group performs transport measurements of semiconductor devices at cryogenic temperatures to study a variety of physical phenomena such as: the spin-orbit interaction (SOI), heavy-hole light-hole mixing, proximization of semiconductors with superconductors, quantum hall effect, thermodynamics.

Prof. P. Maletinsky's group

Our research is directed towards the development and application of sensors based on individual, well-controlled quantum systems ("quantum sensing"). The workhorse for our experiments is the Nitrogen-Vacancy centre in diamond, whose exceptional spin and optical properties render it an ideal candidate for various nanoscale sensing tasks. A major topic we are interested in is nanoscale magnetic and optical imaging for various applications in solid-state and mesoscopic physics. Furthermore, we investigate nanomechanical oscillators, whose motional degrees of freedom can be efficiently sensed (and potentially even entangled) with single spins.

Prof. E. Meyer's group

The aim is to investigate physics of surfaces on the nanometer-scale. Ultra-sensitive force sensors are being developed. Phenomena, such as true atomic resolution of dynamic force microscopy, friction on the atomic scale, Kelvin force microscopy and mechanical detection of magnetic resonance are studied. One of the ultimate goals is the detection of single spins.

Prof. M. Poggio's group

We are interested in using ultra-sensitive micro- and nano-mechanical resonators to probe quantum states. We study the quantum behavior of small mechanical structures, their coupling to single electron states, to spin states, to light, and to the larger environment around them. Sensors able to detect the tiny forces arising from single charges or spins allow the study of a wide class of problems in condensed matter physics. Improved understanding of these phenomena may lead to new high resolution nano- and atomic-scale imaging techniques.

Prof. C. Schönenberger's group

Our research is directed towards static and dynamic electric-transport properties of nanostructures of various kind including normal metals, superconductors, and organic conductors. The structures are fabricated either by high-resolution electron-beam lithography or by using a chemical approach.

Prof. T. Smolenski's group

Our group utilizes low-temperature magneto-optical and quantum-optical spectroscopy to investigate collective electronic, excitonic, and spin phenomena in tunable atomically-thin quantum materials. In our lab, we design and assemble new classes of highly-controllable van der Waals heterostructures and probe them with various opto-electronic techniques, including linear or non-linear spectroscopy, ultra-fast time-resolved experiments, super-resolution imaging etc. This allows us to access novel strongly correlated phases of matter such as electronic crystals, topological liquids or unconventional magnets, as well as to explore their quantum phase diagrams with a variety of tuning knobs, such as bias voltage, magnetic field, strain, externally-tunable spatial confinement etc. This research enables us not only to answer outstanding fundamental questions of condensed matter physics, but also to open new vistas for quantum technologies and quantum computing.

Prof. P. Treutlein's group

Our research focuses on the quantum physics of ultracold atoms and on their interactions with solid-state micro- and nanostructures. The main experimental tool is an atom chip, which allows us to laser cool, trap, and coherently manipulate ultracold atoms at micrometer distance from a chip surface. We use tailored potentials generated by microstructures on the chip to perform quantum atom optics experiments with Bose-Einstein condensates (BECs).

Prof. R. Warburton's group

The Nano-optics lab is investigating charge and spins physics in optically active quantum dots, ultra-microscopy and bio-imaging, semiconductor physics, optics of semiconductor heterostructures and nanostructures.

Prof. I. Zardo's group

The Nanophononics lab is investigating lattice dynamics and phonon transport in nanostructures, which allow to engineer phonons to a larger extent compared to bulk materials. In particular, the manipulation of phonons as coherent waves in solids is expected to allow fine control of heat conduction, which is of fundamental scientific interest and has promising technological impact. Furthermore, we study the interaction between phonons and charge carriers, spins, and photons, which is known to be pivotal in electronic, optoelectronic, quantum, sonic, and thermal devices.

Prof. D. Zumbühl's group

Research focuses on mesoscopic and nanoscale physics, quantum coherence, spin and electron interactions in semiconductor nanostructures such as laterally gated quantum dots in GaAs 2D electron gases as well as graphene. We are pursuing coherent manipulation of quantum mechanical degrees of freedom in solid state nanostructures with the ultimate goal of implementing quantum computation schemes, for example in coupled electron spin qubits.
