Finite-temperature critical behaviors in 2D long-range quantum Heisenberg model

The Mermin-Wagner theorem states that spontaneous continuous symmetry breaking is prohibited in systems with short-range interactions at spatial dimension D ≤ 2. For long-range interactions with a power-law form (1/r^a), the theorem further forbids ferromagnetic or...

HKU and HKUST Physicists Unlock Controllable Nonlinear Hall Effect in Twisted Bilayer Graphene - Promising for Diverse Application in New Materials and Quantum Information Industries

A team of international researchers led by The University of Hong Kong (HKU) and The University of Science and Technology (HKUST) has made a significant discovery in the field of quantum materials, uncovering the controllable nonlinear Hall effect in twisted bilayer graphene. The findings,...

HKU Astrophysicists Reveal the Nature of Dark Matter through the Study of Crinkles in Spacetime

Revealing the Nature of Dark Matter through Studying Crinkles in Spacetime - Dr Jeremy LIM, Physics (YouTube)Most of the matter in the universe, amounting to a staggering 85% by mass, cannot be observed and consists of particles not accounted for by the Standard Model of Particle Physics (see...

HKU astronomy research team unveils one origin of globular clusters around giant galaxies

A study led by Dr Jeremy Lim and his Research Assistant, Miss Emily Wong, at the Department of Physics of The University of Hong Kong (HKU), utilizing data from the Hubble Space Telescope, has provided surprising answers to the origin of some globular clusters around giant galaxies at the centers...
