  Theoretical Spectroscopy Lectures

  school · in-person · Lausanne, CH · CECAM

  This school covers ab initio methods for predicting spectroscopy beyond ground-state DFT, focusing on Time-Dependent Density-Functional Theory (TDDFT) and Many-Body Perturbation Theory (MBPT), including Green's function methods. It also introduces modern topics like machine learning for valence and core-level spectroscopy, X-ray spectroscopies (including RIXS), and automated workflows for ab initio simulations. The school combines theoretical lectures with hands-on computational sessions using state-of-the-art codes.

  Interfacial charge, spin in energy and quantum materials, APS Global Physics Summit Apr 11-16 2027, Atlanta, GA, USA Dear colleagues, I would like to invite you to submit your abstract for the session on "Interfacial charge, spin, and chemical dynamics in energy and quantum materials" (session 15.01.11) at the 2027 APS Global Physics Summit, to be held April 11-16 2027 in Atlanta Georgia, USA. A brief description of the Focus Session is below. I look forward to seeing you in Atlanta, Oliver Monti University of Arizona A deep understanding of spin, charge and energy transfer across materials interfaces is crucial for developing next-generation energy storage and conversion systems as well as novel electronic, spintronic and opto-electronic devices. These interfaces are the drivers of spin injection, charge separation, and charge transfer, which are essential for the functionality of the systems and devices. They are inherently complex and evolve under device operation, often constituting bottlenecks for device performance and sometimes leading to materials degradation and failure. The dynamic evolution of the atomic structure at the materials interface coupled with electron dynamics governs energy, spin, and charge transport through the interface. Developing an understanding of these interfacial dynamics is challenging both for imaging and spectroscopy in experiments and for computational simulations due to the multiple temporal and spatial scales as well as the types of interactions involved. This session highlights recent progress in theory and simulation methods and their application to modeling dynamics at solid-solid interfaces, including 2D materials, topological materials, chirality-induced spin selectivity, and solid-gas phase interfaces of relevance to energy and quantum materials, as well as experimental studies to be interpreted through or integrated with such computational approaches. We expect this session to bring together contributions from research on method development and its application to the simulations of charge, spin, and chemical dynamics and energy, charge, and spin transport through materials interfaces, including those of organic and hybrid organic/inorganic structures and devices. This session will include theory and method development for electron-phonon coupling, spin-orbit interactions, and excited state dynamics for solid surfaces and interfaces, and for machine-learning models for accelerated prediction of complex interfacial dynamics including non-adiabatic processes and quantum coherent phenomena. It will also include experimental studies that elucidate the spin and charge dynamics and transport at the interfaces.
