Traditionally spectroscopy in the electron microscope was limited to UV and X-ray energies. We are now in a position to explore excitations in the visible and IR regions at nanometer spatial resolution. I shall show some of the results on colour centers in fluorite, and what is likely to be the signature of an NV center in diamond. Radiation damage has been a serious problem in electron microscopy of biological specimens. Low energy vibrational mode excitations can be delocalized over distances of up to 100 nm. Although the delocalization limits spatial resolution, it means that we can record spectra with beams positioned outside the specimen (aloof mode). I shall show results from a collaboration with Weizmann# where we demonstrate excitation of vibrational modes in guanine with no beam induced damage since in aloof mode we don’t excite transitions leading to ionization.

The model describes the macroscopic behavior of plasmas confined by magnetic fields. One form of the model, known as “ideal MHD”, has received extensive study, even leading to the publication of several related textbooks. The ideal MHD model is useful because of its relative simplicity making it amenable to both theoretical and computational analysis. However, a considerable number of assumptions have to be made to derive the model. The question then is whether the resulting model is actually useful in understanding and predicting experimental performance or just offers some general guidelines concerning plasma behavior. In the seminar the assumptions used in the derivation of the model plus the model’s basic physical properties will be discussed with specific application to the Z-Pinch experiment at the Weizmann Institute. Does the model make reliable predictions for the Z-Pinch experiment? We shall see. -

Defects are found in 2D materials as well as bulk. Their quantum properties on the one hand mimic atomic systems but as well reveal molecular or solid state properties. The talk shall highlight two particular use of defects for quantum technology. 1) As optically active defects couple to light fields. They are excellent systems for quantum repeater nodes. They both show strong interaction with the light field and on the other hand do have very good quantum memory capabilities due to local nuclear spins. I will show efficient storage of photon to nuclear spin coherence and discuss the potential for generating strings of entangled photons using single defect. 2) Diamond defects are excellent tools for nanoscale quantum sensing. The long spin coherence times of such defects even under ambient conditions close to surfaces make them highly suited for spin-based detection of various quantities. The talk shall describe nanoscale sensing of electric, magnetic fields, temperature etc. utilizing spin quantum sensors. Applications in such diverse areas like solid-state physics or cellular biology shall be discussed. -
