Vor 6 Tagen · Theoretical physics is the development of mathematical formalisms and computational protocols for describing all aspects of objects found in the world around us and their interaction.
15. Apr. 2024 · Physicists debate Universe-expansion data. Results from the telescope could help to end a long-standing disagreement over the rate of cosmic expansion. But scientists say more measurements are...
Vor 3 Tagen · Abstract. Within the framework of general relativity, we explore the interior of the Schwarzschild black hole before complete collapse occurs, finding that the exterior is perfectly compatible with a source much more complex than a pointlike mass. We provide a set of inner geometries for singular and regular black holes that smoothly joint the ...
Vor 3 Tagen · Tracy R. Slatyer, the Edward, Frances, and Shirley B. Daniels Fellow and a theoretical physicist who works on particle physics, cosmology, and astrophysics, will research the mysterious nature and interactions of dark matter by studying the possible signature of new physics in astrophysical and cosmological data. She was the co-discoverer of the giant structures known as “Fermi bubbles ...
16. Apr. 2024 · Schedule. Monday 15 April. Tuesday 16 April. Scientific discussion meeting organised by Professor James Binney FRS, Dr Roya Mohayaee, Professor John Peacock FRS and Professor Subir Sarkar.
1. Mai 2024 · Physicists have done a remarkable job explaining the chaos of the universe with well-behaved equations, but certain situations remain mysterious. Among these are collections of many tiny particles — they can be atoms, electrons, anything sufficiently small — that interact in surprising and complicated ways.
Vor 3 Tagen · Non-Hermitian quantum metrology, an emerging field at the intersection of quantum estimation and non-Hermitian physics, holds promise for revolutionizing precision measurement. Here, we present a comprehensive investigation of non-Hermitian quantum parameter estimation in the quantum regime, with a special focus on achieving Heisenberg scaling.
