(2023-09-15)Monte Carlo event generators are nowadays indispensable tools for predictions based on first principles in high energy physics, and they represent one of the mainstays of particle physics research at the Large Hadron ... -
Structure Investigations of LiMn2O4 as Oxygen Evolution Reaction Catalyst
(2023-09-15)The catalytic activity of a material is determined by the electronic structure and atomic arrangements at its surface. In particular, eg occupancy of octahedral cations has been found to be a successful descriptor of the ... -
Topological charge pumping in ultracold quantum gases
(2023-09-13)A topological charge pump is a one-dimensional, dynamical analogue of a quantum Hall system that is particularly well suited for studying topology, both theoretically and experimentally, since no synthetic gauge fields are ... -
Investigation of Physical and Chemical Effects in Sonicated Small Flow Channels
(2023-09-08)In the framework of intensification of chemical processes, miniature continuous flow reactors have come into focus in recent time. As a specific way of “non-classical” energy supply to the liquid in such a flow reactor, ... -
Phase-Dependent Energy Dissipation Processes in La0.7Sr0.3MnO3 and (La0.6Pr0.4)0.7Ca0.3MnO3 after an Ultrashort Optical Excitation
(2023-08-31)La0.7Sr0.3MnO3 (LSMO) and (La0.6Pr0.4)0.7Ca0.3MnO3 (LPCMO) are perovsikte manganites which both show a ferromagnetic-to-paramagnetic phase transition. Interestingly, the development of the new phase when crossing the ... -
Correlated phases in the vicinity of tunable van Hove singularities in Bernal bilayer graphene
(2023-08-18)The naturally occurring Bernal bilayer graphene exhibits a complex low-energy band structure hosting electric-field-controlled Lifshitz transitions and van Hove singularities. The diverging density of states is predicted ... -
Resource Bounded Agency in Public goods Games
(2023-07-28)The new and emerging field of sociophysics aims to explain and understand collective behavior demonstrated by humans in a variety of domains. This usually requires to make some assumptions about the microscopic inter-human ... -
Analytic studies on the SYK models: from instantaneous thermalization to holographic duality
(2023-07-18)The quasiparticle picture is so prominent in condensed matter physics that it is almost taken as an axiom. Without this simplification, the physics becomes nearly intractable. However, the physics also becomes remarkable, ... -
Interlayer effect on the hydrogen uptake in Vanadium films: Stress development, surface topography and optical behavior changes
(2023-07-13)The purpose of this study is to investigate hydrogen absorption-related properties changes of nanocrystalline thin films by varying the elastic constraints condition. The elastic constraint condition is varied by using ... -
Spanwise rotating convection in an ideal gas
(2023-06-23)Spanwise rotating convection is a model for the equator region of planets like Jupiter or Earth's outer liquid core. Direct numerical simulations of the Navier-Stokes, and continuity equation as well as an equation for the ... -
Quantitative Hemodynamics using Magnetic Resonance Imaging, Computational Fluid Dynamics and Physics-informed Neural Network
(2023-06-20)Hemodynamics is related to blood flows in the circulatory system under normal and pathological conditions to understand the mechanisms of various diseases and to treat them accordingly. Different methods, with their own ... -
Dynamical remodeling of visual circuit architecture
(2023-06-14)Visual cortex, as a model for plasticity, has been studied for many years. It is still controversial, however which mechanisms guide the emergence and development of a hallmark of the cortical functional architecture, ... -
Pixel Detector Studies for the ATLAS ITk Upgrade for the HL-LHC
(2023-06-02)The integrated luminosity of the Large Hadron Collider (lhc), which is proportional to the number of particles colliding and thus data being collected, is planned to be increased by a factor of 5-7.5 compared to the ... -
Orbital-order phase transition and non-adiabatic quantum-classical dynamics in strongly coupled electron-phonon systems
