| 09:00 - 10:30 Optical Microscopy School CMNL structure and application of Optical Microscopy 11:00 - 12:00 Computational nanoscience biweekly journal club First-Principles Atomic Force Microscopy Image Simulations with Density Embedding Theory School NANO SCIENCES First-Principles Atomic Force Microscopy Image Simulations with Density Embedding Theory We present an efficient first-principles method for simulating noncontact atomic force microscopy (nc-AFM) images using a "frozen density" embedding theory. Frozen density embedding theory enables one to efficiently compute the tip-sample interaction by considering a sample as a frozen external field. This method reduces the extensive computational load of firs-principles AFM simulations by avoiding consideration of the entire tip-sample system and focusing on the tip alone. We demonstrate that our simulation with frozen density embeddin ... 13:30 - 15:00 Weekly Seminar On Adiabatic Modes and violation of consistency relations in Cosmology School ASTRONOMY There is a celebrated theorem by Steven Weinberg, stating that the perturbations in the curvature of the universe on large scales is almost constant. The conservation of the curvature must be seen as a cornerstone of Cosmology since otherwise, one can not relate the early universe initial condition on the statistics of cosmological perturbations to the late-time observations of CMB and LSS. Weinberg uses coordinate transformation invariance of General Relativity to prove this conservation. Consistency relations in Cosmology, on the other hand, are unique tools to discriminate between single field and multiple field models of inflation ... 14:00 - 15:00 Combinatorics and Computing Weekly Seminar Vertex-shifts on unimodular random graphs School MATHEMATICS ... 14:00 - 15:00 Weekly Seminar Condensed Matter and Statistical Physics Group Two nanostructured platforms: MoS2 / MoOx (x=2 and 3) composite and porous Si School PHYSICS Classroom A ... 14:00 - 15:00 Weekly Seminar Two nanostructured platforms: MoS2 / MoOx (x=2 and 3) composite and porous Si School NANO SCIENCES Two nanostructured platforms: MoS2 / MoOx (x=2 and 3) composite and porous Si In this talk, I will report on two nanostructured platforms: the MoS2 and MoOx (x=2 and 3) composite thin layers, electrodeposited, onto a Florine doped Tin Oxide (FTO) substrate and porous Si (Psi). In the first platform, our results show a change in relative content of these compounds in different thicknesses ranging from ~20 to 540 nm. The Optical and electrical bandgaps reveal a tunable behavior by controlling the relative content. In addition, a sharp transition from p to n-type of semiconductivity is observed. We find that the spin-orbit inte ... 15:00 - 16:00 Weekly Seminar Extra Dimension Searches At CMS School PARTICLES AND ACCELERATORS Arkani-Hamed, Dimopoulos, and Dvali (ADD) proposed that extra spatial dimensions could potentially solve the standard model hierarchy problem. They proposed a scenario whereby the SM is constrained to the common 3 + 1 space-time dimensions, while gravity is free to propagate throughout a larger multidimensional space. In this talk I will review part of CMS searches in this area after a brief introduction to the model. Larak Seminar Room ... |
