The collective motion of animals in a group is a fascinating topic of research for many scientists. Understanding these collective behaviors can sometimes inspire the development of strategies for promoting positive social change, as well as technologies that emulate...
Teams of astrophysicists worldwide are trying to observe different possible types of dark matter (DM), hypothetical matter in the universe that does not emit, absorb or reflect light and would thus be very difficult to detect. Fermionic DM, however, which would be...
Excitons are quasiparticles that are formed in insulators or semiconductors when an electron is promoted to a higher energy band, leaving a positively charged hole behind.
Stochastic thermodynamics is an emerging area of physics aimed at better understanding and interpreting thermodynamic concepts away from equilibrium. Over the past few years, findings in these fields have revolutionized the general understanding of different...
Researchers at the National Institute of Standards and Technology (NIST), Massachusetts Institute of Technology (MIT) and the Perimeter Institute recently set new constraints on dark photons, which are hypothetical particles and renowned dark matter candidates. Their...
High-energy neutrinos are highly fascinating subatomic particles produced when very fast charged particles collide with other particles or photons. IceCube, a renowned neutrino detector located at the South Pole, has been detecting extragalactic high-energy neutrinos...
The Berry curvature and Chern number are crucial topological qualities of a quantum mechanical origin characterizing the electron wave function of materials. These two elements play a very important role in determining the properties of specific materials.
Physicists studying quantum many-body physics very rarely reach exact solutions or conclusions, particularly in more than one dimension. This is also true for the Fermi polaron problem, describing instances in which the many-body quantum background is a...
Floquet topological insulators are materials with topological phases that originate from tailored time-dependent perturbations of their crystal structure. These materials have been proved to feature highly unusual electron conduction properties. In recent years, there...
Dark matter is a type of matter in the universe that does not absorb, reflect or emit light, which makes it impossible to directly detect. In recent years, astrophysicists and cosmologists worldwide have been trying to indirectly detect this elusive type of matter, to...
