First observation of Bose–Einstein condensation of two-magnon bound state in spin-1 triangular lattice reported

Using the Multi-frequency High Field Electron Spin Resonance Spectrometer at the Steady-State High Magnetic Field Facility (SHMFF), researchers observed the first-ever Bose–Einstein condensation (BEC) of a two-magnon bound ...

Quantum control of collisions possible beyond ultralow temperatures, study shows

At ultracold temperatures, interatomic collisions are relatively simple, and their outcome can be controlled using a magnetic field. However, research by scientists led by Prof. Michal Tomza from the Faculty of Âé¶¹ÒùÔºics of ...

Einstein's light quanta through the lens of Maxwell's equations

Light was long considered to be a wave, exhibiting the phenomenon of interference in which ripples like those in water waves are generated under specific interactions. Light also bends around corners, resulting in fringing ...

Gravitational waves may prove black holes' quantum effect and resolve the dark matter problem

Black hole quantum effects are usually thought to be too small to have any observable signatures. This is indeed the case for heavy black holes, such as the ones detected via gravitational waves by LIGO in 2015. These black ...

Quantum simulators: When nature reveals its natural laws

Quantum physics is a very diverse field: it describes particle collisions shortly after the Big Bang as well as electrons in solid materials or atoms far out in space. But not all quantum objects are equally easy to study. ...

Very cold detectors reveal very hot universe and kick off a new era in X-ray astronomy

X-rays are radiated by matter hotter than one million Kelvin, and high-resolution X-ray spectroscopy can tell us about the composition of the matter and how fast and in what direction it is moving. Quantum calorimeters are ...

Âé¶¹ÒùÔºicists uncover strong light-matter interactions in quantum spin liquids

Âé¶¹ÒùÔºicists have long theorized the existence of a unique state of matter known as a quantum spin liquid. In this state, magnetic particles do not settle into an orderly pattern, even at absolute zero temperature. Instead, ...
