Magnetic materials play an important role in the industry. Except for common
material parameters such as magnetocrystalline anisotropy, magnetoelastic
behavior can be significant for application serving in various devices, e.g. in
acoustic ...

In recent years, the behavior of dislocations in random solid solutions has
received renewed interest, and several models have been discussed where random
alloys are treated as effective media containing random distributions of
dilatation a...

Finite-horizon probabilistic multiagent concurrent game systems, also known
as finite multiplayer stochastic games, are a well-studied model in artificial
intelligence due to their ability to represent a wide range of real-world
scenarios i...

We explicitly demonstrate the universality of critical dynamics through
unprecedented large-scale GPU-based simulations of two out-of-equilibrium
processes, comparing the behavior of spin- Ising and spin- Blume-Capel
models on a squ...

Mass loss governs the evolution of massive stars and shapes the stellar
surroundings. To quantify the impact of the stellar winds we need to know the
exact mass-loss rates; however, empirical constraints on the rates are hampered
by limited...

Gravitational waves (GWs) from compact binary coalescences (CBCs) provide a
new avenue to probe the cosmic expansion, in particular the Hubble constant
. The spectral sirens method is one of the most used techniques for GW
cosmology. I...

We investigate higher-point correlators in the BFSS matrix model, a
non-conformal theory dual to type IIA string theory, using Witten diagrams and
techniques from the amplitudes program. While the Witten diagrams are more
complex than those...

Advancements in VLBI instrumentation, driven by the geodetic community's goal
of achieving positioning accuracy of 1 mm and stability of 0.1 mm/y, have led
to the development of new broadband systems. Here, we assess the potential of
these ...
