Ultracold atoms dressed by light simulate gauge theories

Our modern understanding of the physical world is based on gauge theories: mathematical models from theoretical physics that describe the interactions between elementary particles (such as electrons or quarks) and explain ...

New faint, distant and cold brown dwarf discovered

Using the James Webb Space Telescope (JWST), an international team of astronomers have detected a new faint, distant, and cold brown dwarf. The newly found object, designated GLASS-JWST-BD1, turns out to be about 31 times ...

In search of universal laws of diffusion with resetting

The manner in which animals penetrate a neighborhood searching for food shows similarities to the movements of liquid particles in plant capillaries or gas molecules near an absorbing wall. These phenomena—and many others ...

Demystifying DNA hybridization kinetics

Nanoscientists and theoretical physicists at UNSW Medicine & Health's EMBL Australia Node in Single Molecule Science joined forces to demystify the complicated mechanisms governing how quickly two matching strands of DNA ...

Secret language of cells? New cell computations uncovered

Throughout evolution, individual cells have been making successful decisions on their own, even while forming parts of vast networks, such as neurons and glia in the human brain. Now scientists from King Abdullah University ...

Present and future of nonlinear optical metasurfaces

One of the main objectives of optics is the control of light propagation and confinement. Progress in optics historically started with the development of bulky lenses and mirrors, then prisms and gratings, and so on. The ...

Predicting the phase stability of soft matter

Soft matter is an important class of materials that typically consists of colloidal particles and/or polymers in a liquid medium. For certain compositions, these types of systems tend to (micro-)phase separate and unmix into ...
