Secular evolution of spiral galaxies in non-Newtonian theories

School
ASTRONOMY

In this talk, I first review some major tensions of the standard dark matter paradigm in local self-gravitating systems. Then I discuss the evolution of exponential galactic disks in the context of the main alternative theories which deny the existence of dark matter particles and instead use different gravity law or dynamics to mimic the dark matter behavior. More specifically, I report the results of a series of high-resolution galactic simulations conducted in the context of four different gravity theories: Newtonian gravity, Modified Newtonian Dynamics (MOND), a model of nonlocal gravity model (NLG), and a scalar-tensor-vector gravity th ...

Two-dimensional Materials and Their Applications

Abstract:

Two-dimensional (2D) crystals are atomically thin materials that offer a wide range of physical and chemical properties that can be engineered for targeted applications. In particular, they allow fabrication of unconventional and efficient devices for (opto)electronic, sensing, and energy applications. Advances in manipulating 2D structures and heterostructures at the atomic level enable to engineer their functionalities specific to certain applications. Different techniques for fabrication and processing of 2D materials and heterostructures will be ...

Precise determination of quark masses from lattice-QCD simulations

School
PARTICLES AND ACCELERATORS

Abstract: Quantum chromodynamics (QCD) as a part of the standard model of particle physics describes the physics of quarks and gluons. Perturbation theory can be used to solve problems involving very high energies, but it breaks down at low energies forcing us to employ nonpertubrative approaches. Lattice QCD is the dominant approach to solve QCD numerically from first principles. Effective field theories (EFTs) such as heavy quark effective theory (HQET), on the other hand, provide analytic methods to describe the low-energy dynamics of QCD.
In this talk, we discuss determination of quark masses from a combined EFT and lattice-QCD ana ...
