Controlling spins with light.
The interaction of sub-picosecond laser pulses with magnetically ordered materials has developed into an extremely exciting research topic in modern magnetism. From the discovery of sub-picosecond demagnetization over a decade ago to the recent demonstration of magnetization reversal by a single 40 fs laser pulse, the manipulation of spins by ultrashort laser pulses has become a fundamentally c...
متن کاملPhD Position: Controlling spins by squeezing crystals
A first glance the title of this project may seem very strange. How can we control the properties of a quantum particle by simply squeezing a crystal? Electron or nuclear spins can be trapped in defects such as vacancies in a crystal structure. This of course is a “particle in a box”, and if we change the shape of the box by squeezing the crystal we can change the energy levels of the particle....
متن کاملNonlinear plasmonics: controlling light with light
Many scientists believe that the future of signal processing and computing lies not within electronics but in the field of subwavelength optics. Controlling light at sub-wavelength scales, forbidden by traditional far-field optics, relies on surface plasmon techniques. Surface plasmon polaritons (SPPs) are electromagnetic waves that exist on the surface of metals such as gold or silver. The int...
متن کاملControlling light-with-light without nonlinearity
According to the fundamental Huygens superposition principle, light beams traveling in a linear medium will pass though one another without mutual disturbance. Indeed, the field of photonics is based on the premise that controlling light signals with light requires intense laser fields to facilitate beam interactions in nonlinear media, where the superposition principle can be broken. Here we c...
متن کاملControlling spins in adsorbed molecules by a chemical switch
The development of chemical systems with switchable molecular spins could lead to the architecture of materials with controllable magnetic or spintronic properties. Here, we present conclusive evidence that the spin of an organometallic molecule coupled to a ferromagnetic substrate can be switched between magnetic off and on states by a chemical stimulus. This is achieved by nitric oxide (NO) f...
