Ground State

In a new experiment, physicists have replicated the famous Schrödinger's cat experiment at hotter temperatures than ever before. The breakthrough is a small but significant step toward quantum computers that can work at normal temperatures.

Physicists showed that photons can seem to exit a material before entering it, revealing observational evidence of negative time

ACE, a new DNA-powered signal amplification technology, dramatically increases sensitivity of mass cytometry, opening new windows on many biological and pathological processes

U.S. Naval Research Laboratory (NRL) scientists confirm the identification of a new class of semiconductor nanocrystals with bright ground-state excitons, a significant advancement in the field of optoelectronics, in an article published in the American Chemical Society (ACS) journal ACS Nano.

A dissipative time crystal is a phase of matter characterized by periodic oscillations over time, while a system is dissipating energy. In contrast with conventional time crystals, which can also occur in closed systems with no energy loss, dissipative time crystals are observed in open systems with energy freely flowing in and out of them.

Nuclear power (peaceful and military) is based on atomic fission, unleashing titanic amounts of energy via splitting the nucleus of certain atoms - mainly enriched Uranium U235. In 1944, Otto Hahn received the Nobel Prize for its discovery.  Omitted from recognition was his co-discoverer, the first female physics professor in Germany, Dr. Lisë Meitner.

Electrons swarm in a soup of quantum entanglement in a new class of materials called strange metals

In a new study published in Science today, JILA and NIST (National Institute of Standards and Technology) Fellow Jun Ye and his research team have taken a significant step in understanding the intricate and collective light-atom interactions within atomic clocks, the most precise clocks in the universe.

A team of physicists has produced pure trilobite molecules in rubidium over a wide range of frequencies and characterize their binding energies, lifetimes, and dipole moments.

Only formally discovered in 2016, STEVE is a mysterious atmospheric phenomenon that is linked to yet distinct from the aurora. Here's where to look for it in the night sky.

It's beautiful. It's blue. It's a really big deal.

Researchers at Duke University have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations.

Atomic clocks are the world's most precise timekeepers. Based on periodic transitions between two electronic states of an atom, they can track the passage of time with a precision as high as one part in a quintillion, meaning that they won't lose or gain a second over 30 billion years—more than twice the age of the universe.

The state of perfect stillness known as absolute zero is one of the Universe's impossible achievements.

A team of scientists from the U.S. Department of Energy's Ames National Laboratory demonstrated a way to advance the role of quantum computing in materials research with an adaptive algorithm for simulating materials. Quantum computers have potential capabilities far beyond today's computers, and using an adaptive algorithm allows them to produce solutions quickly and accurately.

From quarks and gluons to giant galaxy clusters, everything that exists in our Universe is determined by what is (and isn't) bound together.

Organic materials with room-temperature phosphorescence (RTP) emission have attracted extensive attention due to extraordinary properties including long lifetime, large Stokes shift, stimuli-responsiveness, and so on, and show bright prospects in broad fields. However, the energy of the excited state of organic phosphors is easily consumed through thermal radiation and collision deactivation.

The 'Hawking radiation' emitted by black holes may be able to carry information after all, a new solution to Stephen Hawking's famous paradox suggests.

In organic solar cells, carbon-based polymers convert light into charges that are passed to an acceptor. This type of material has great potential, but to unlock this, a better understanding is needed of the way in which charges are produced and transported along the polymers.
