First diode for magnetic fields

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.

Nanomagnets Levitate Thanks to Quantum Physics

Cosimo Rusconi and Oriol Romero-Isart

Quantum physicists in Oriol Romero-Isart’s research group in Innsbruck show in two current publications that, despite Earnshaw’s theorem, nanomagnets can be stably levitated in an external static magnetic field owing to quantum mechanical principles. The quantum angular momentum of electrons, which also causes magnetism, is accountable for this mechanism.

Ultrashort and Extremely Precise

A group of theoretical physicists headed by Oriol Romero-Isart observes a surprising quantum effect when short light pulses interact with matter. In the future, this effect may be used for developing a completely new type of far-field light nanoscopes.  

Physicists Design Ultrafocused Pulses

A new scheme to theoretically generate arbitrarily short and focused electromagnetic fields.

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.

Innsbruck is a place that attracts the most intelligent thinkers in Europe. One of these bright minds, Jordi Prat-Camps, has just made it onto the American economic magazine Forbes’ 30 Under 30 Europe lists of ground-breaking leaders. The physicist, a graduate from Barcelona, started working as a researcher at the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck last year.
