| 11:00 - 12:00 Computational nanoscience biweekly journal club Accurate first-principles structures and energies of diversely bonded systems from an efficient density functional School NANO SCIENCES Accurate first-principles structures and energies of diversely bonded systems from an efficient density functional One atom or molecule binds to another through various types of bond, the strengths of which range from several meV to several eV. Although some computational methods can provide accurate descriptions of all bond types, those methods are not efficient enough for many studies (for example, large systems, ab initio molecular dynamics and high-throughput searches for functional materials). Here, we show that the recently developed non-empirical strongly constrained and appropriately normed (SCAN) meta-generalized gr ... 13:30 - 15:00 Weekly Seminar A circumgalactic study at intermediate redshifts School ASTRONOMY Circumgalactic medium (CGM), the interface between the interstellar medium and the intergalactic medium (IGM), is a complicated site of entwined gas from the IGM accretion and galactic outflows. QSO absorption line systems are amongst the best places to study the physical properties of the CGM. MUSE observations of the host galaxy absorbers along with the QSO absorption line data provide a unique set of data to explore the gas flows in CGM. Here I present the results of our recent CGM studies using MUSE observations. In particular, I demonstrate the detailed analysis of a sightline where we find a bonafide candidate for the “cold-flow” disk. ... 14:00 - 15:00 Combinatorics and Computing Weekly Seminar Inverse 1-median problem on weighted graphs School MATHEMATICS ... 14:00 - 15:00 Weekly Seminar Ultracold fermions in a cavity-induced artificial magnetic field School NANO SCIENCES Ultracold fermions in a cavity-induced artificial magnetic field The tailored generation of topologically non-trivial quantum phases is of greatest interest as these phases possess special properties such as extended edge states that can be well protected against destructive environmental effects. The dynamic control and detection of such phases still remain a great challenge. In order to overcome these difficulties, we propose a mechanism by which the dynamical feedback between the atoms and the optical cavity mode leads to the emergence of an artificial magnetic field and to self-organizing topological phases.
