It is well known that carbon-based materials could increase the coherence times of spin qubits, which are among the most developed solid-state qubits. Here, we propose how to form spin qubits in graphene quantum dots. A crucial requirement to achieve this goal is to find quantum-dot states where the usual valley degeneracy in bulk graphene is lifted. We show that this problem can be avoided in quantum dots based on ribbons of graphene with armchair boundaries. The most remarkable new ... 13:30 - 15:00 Weekly Seminar Quasar host galaxies revealed by eclipsing damped Lyman alpha systems School ASTRONOMY Damped Lyman alpha absorption systems (DLAs) with the same redshift as their background quasars, can act as natural coronagraphs, blocking the blazing radiation from the broad line region (BLR) of the quasar, and as a result revealing to us the much fainter emission from the quasar host galaxy. This constitutes a new way to have direct access to the quasar host galaxy, and possibly to the very center of the active galactic nucleus (AGN). We searched the SDSS database and found 26 such eclipsing DLAs that exhibit narrow Lyman-alpha emission in their DLA troughs. We obtained high-resolution echelle spectra of six of these systems using the MagE ... 15:00 Weekly Seminar Dilepton Production and its Significance in Heavy Ion Experiments School PARTICLES AND ACCELERATORS The aim of heavy ions collisions is to study nuclear matter under critical conditions. In this way many observables deserve to shed light on the collective structure of ions after collision. Dileptons as a yield of electromagnetic interactions which caused by photon has a crucial role, since its profile can give us valuable information about resonance location, modification of intermediate hadrons and etc. Also photon solely is valuable signal in heavy ion experiments, since it goes out from all the stages after collision and is a neat sign to explore properties of different stages. In this talk we would like to introduce some preliminary iss ... |
