Reinhard Maurer
Research Focus
Our research vision is to develop and apply new simulation methods and prediction tools that fuse machine learning (ML) and data-driven approaches with electronic structure and dynamical simulation methods. Doing so removes existing bottlenecks in simulation capabilities that limit the length and time scales and the complexity of molecular/materials simulations. More importantly, hybrid ML/QM methods enable fundamentally new prediction approaches that defy the conventional structure-to-property paradigm that underpins modern computational materials discovery.
We are interested in application areas ranging from heterogeneous photo-/electrocatalysis, new energy conversion materials, nanostructured and functionalized interfaces, to controlled materials fabrication. In the past, we have studied energy transfer and dissipation processes in hydrogen-metal chemistry, hyperthermal scattering, and light-driven surface dynamics with custom-built simulation methods and machine learning models.
Research environment
The Maurer group is an internationally recognised research group that develops and applies new computational simulation methods and prediction tools for computational materials discovery and surface science. The group is truly international in location and membership. The total of currently 20 team members are hosted across the University of Vienna and the University of Warwick, with close links ensured by hybrid meetings, regular site visits and retreats. The group works in close collaboration with many international collaborators.
The group is part of the Computational Materials Physics division of the Faculty of Physics, which hosts three world-leading research groups, creating a vibrant environment in newly renovated and centrally located offices.
We codevelop several electronic structure software packages and have built a comprehensive in-house stack of open-source software for mixed quantum-classical dynamics simulations and machine learning workflows written in Python, Julia.
Expectations towards postdoctoral fellows in this programme

In a career that has consistently applied both simulation and experiment in complementary ways, his research has ion implantation, x-ray photoelectron and electron energy-loss spectroscopies, understanding and modeling of electron irradiation effects, and advanced scanning transmission electron microscopy of low-dimensional and other materials. Most recently, his research focus has been increasingly on electron ptychography and quantitative scattering simulations using first-principles potentials derived from density functional theory. His most notable recent contribution to transmission electron microscopy is the massively parallel open-source Python simulation code abTEM, which is the fastest and most modern software package used by an increasingly large part of the field.
Research environment
The host group has for over a decade pioneered research on the atomic structure and tailoring of low-dimensional materials, enabled by highly customized experimental infrastructure centered on an aberration-corrected ultra-high vacuum scanning transmission electron microscope Nion UltraSTEM 100. Uniquely in the world, this microscope is connected through a direct vacuum sample transfer to an adjacent modular experimental setup currently spanning two floors that allows the creation and tailoring of atomic structures. The current microscope within the modular system will be replaced by 2026 with the latest-generation High Energy Resolution Monochromated EELS STEM microscope from Bruker. It will allow the study of quantum-mechanical quasiparticle excitations and interactions at an unprecedented energy and momentum resolution, the imaging of charge densities, electric and magnetic fields, and super-resolution computational microscopy.
Expectations towards postdoctoral fellows in this programme
Depending on the interests and qualifications of the applicant, either computational, experimental, or combined projects can be conducted under the supervision of Prof. Susi.

From successful candidates, we expect a background in transmission electron microscopy or electron diffraction, a track record of peer-reviewed publications commensurate with the career stage, and at least basic knowledge of and experience with the Python programming language. Expertise in aberration-corrected instruments or computational microscopy and first principles methods, as well as open-science contributions including data and code will be further appreciated. Good communication and writing skills in English are a must.

Research Focus
“How does a quantum object gravitate?”, “How far can we push massive objects into the quantum regime?”, “How well can we measure gravity of microscopic systems?”. Such questions and their implications for the foundations of physics are the driving force behind our research.

Possible research themes or topics for postdoctoral projects
The main research activities of the Aspelmeyer group include quantum optical control of levitated solid-state objects, the exploration of their quantum properties for fundamental questions and novel quantum technology platforms, as well as precision measurements of ultra-weak gravitational forces. On the quantum side, we explore the extreme regime of motional quantum states of solids and their interactions to understand how to maximize mass, delocalization, and coherence time in quantum experiments. On the gravity side, we explore the extreme regime of gravitational phenomena of miniature source masses to understand how to isolate gravity from all other interactions on a microscopic scale. You will be part of one of those activities.
