Improved models of heavy ion collisions reveal new details of early universe nuclear matter

A researcher, Heikki Mäntysaari from the University of Jyväskylä (Finland), has been part of an international research group that has made significant advances in modeling heavy ion collisions. New computer models provide additional information about the matter in the early universe and improve our understanding of the extremely hot and dense nuclear matter. The work […]

Quantum error correction codes enable efficient scaling to hundreds of thousands of qubits

A new class of highly efficient and scalable quantum low-density parity-check error correction codes, capable of performance approaching the theoretical hashing bound, has been developed by scientists at the Institute of Science, Tokyo, Japan. These novel error correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, […]

High-order analysis reveals more signs of phase-change ‘turbulence’ in nuclear matter

Members of the STAR collaboration, a group of physicists collecting and analyzing data from particle collisions at the Relativistic Heavy Ion Collider (RHIC), have published a new high-precision analysis of data on the number of protons produced in gold-ion smashups over a range of energies.

World’s most sensitive detector tightens the net on on elusive dark matter

Determining the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world’s most sensitive dark matter detector, LUX-ZEPLIN (LZ), have narrowed down the possibilities for one of the leading dark matter candidates: weakly interacting massive […]

‘A real physical thing’: Quantum computer exhibit at O’Hare seeks to make the technology tangible

Chicago has quickly emerged as a hub for quantum computing, with the state of Illinois and technology companies pouring millions of dollars into developing a campus to build the world’s first commercially viable quantum computer on the city’s Southeast Side.

Electrically tunable metasurface unlocks real-time THz holography

The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging. However, manipulating THz waves has long been a technical challenge, since these frequencies interact weakly with most natural materials.

Physicists realize time-varying strong coupling in a magnonic system

Time-varying systems, materials with properties that change over time, have opened new possibilities for the experimental manipulation of waves. Contrarily to static systems, which exhibit the same properties over time, these materials break so-called temporal translation symmetry. This in turn prompts the emergence of various fascinating phenomena, including time reflection, refraction and diffraction.

New perspectives on light-matter interaction: How virtual charges influence material responses

Understanding what happens inside a material when it is hit by ultrashort light pulses is one of the great challenges of matter physics and modern photonics. A new study published in Nature Photonics and led by Politecnico di Milano reveals a hitherto neglected but essential aspect, precisely the contribution of virtual charges, charge carriers that […]

Coexisting magnetic states in 2D material promise major energy savings in memory chips

It is anticipated that within just a few decades, the surging volume of digital data will constitute one of the world’s largest energy consumers. Now, researchers at Chalmers University of Technology, Sweden, have made a breakthrough that could shift the paradigm: an atomically thin material that enables two opposing magnetic forces to coexist—dramatically reducing energy […]
