It carries one fundamental unit of electric charge, and every electron is exactly the same. But under extreme conditions, large numbers of electrons act together and give rise to new quantum objects called quasiparticles. These act as if they carry only a fraction of an electron's charge, making them one of the strangest phenomena in modern physics. https://phys.org/news/2026-08-graphene-device-fractional-electric-quantum.html Condensed Matter Mon, 17 Aug 2026 13:40:10 EDT news706185841 A study has been published in Nature Communications that identifies an unusual regime of quantum oscillations in a three-dimensional topological insulator.

The extreme environment inside these devices, however, can damage materials that surround the superheated, electrically charged plasma where the nuclear fusion reaction takes place. https://phys.org/news/2026-08-tungsten-fusion-reactors.html Condensed Matter Sat, 15 Aug 2026 08:40:01 EDT news705839207 Future fusion power plants aim to recreate the heart of a star here on Earth to power our future energy needs. While the core fusion plasma will burn at hundreds of millions of degrees, the surrounding structural components must handle sudden, punishing heat loads that rival the extreme temperatures faced by spacecraft upon reentry into Earth's atmosphere. Copper and its alloys are primary candidates for handling these intense heat fluctuations, making it vital to understand exactly how the metal behaves when pushed to its melting point. https://phys.org/news/2026-08-copper-behavior-insights-future-fusion.html Condensed Matter Thu, 13 Aug 2026 15:20:03 EDT news705842131 Diamond is more than a dazzling gem—the extremely hard form of carbon makes up the pellet that encases fuel for inertial confinement fusion, and scientists believe it rains down deep inside ice giant planets like Neptune and Uranus. In both cases, the material experiences enormous pressures. Until now, experiments and simulations have disagreed about how it actually behaves under those conditions. https://phys.org/news/2026-08-diamond-triple-fusion-gain-secrets.html General Physics Thu, 13 Aug 2026 11:40:05 EDT news705836281 Altermagnetism is a new, third type of magnetism of great interest for spin-transport applications like computer memory. If properly harnessed, it could combine the benefits of the two existing types of magnetism, ferromagnetism and antiferromagnetism, ultimately reducing or eliminating heat during information transfer and increasing the ability to miniaturize next-generation technologies.

Heatsinks, fans, cold plates and refrigerators are bulky exterior measures bolted onto a chip or package after the fact. They treat heat as a single averaged quantity to be removed in bulk, even though the heat is actually produced locally, component by component, deep inside the circuitry. https://phys.org/news/2026-08-quantum-circuits-electronics-oldest-power.html Condensed Matter Mon, 10 Aug 2026 16:40:10 EDT news705585471 In January 2024, physicists at TU Dortmund University demonstrated a continuous time crystal in a semiconductor whose oscillations remained stable for hours.

As the phonons move through a material, they propagate that circular motion, or angular momentum, through the material. The angular momentum serves as the source of spin, and the chirality dictates the direction of the spin, enabling spin control in spintronics. https://phys.org/news/2026-08-electric-field-reverses-phonon-chirality.html Condensed Matter Wed, 05 Aug 2026 15:00:06 EDT news705151382 Bose-Einstein condensates (BECs) are often described as a "fifth state of matter": a quantum state in which many particles lose their individual identities and behave as one collective object. For more than 60 years, researchers have sought to create such condensates from excitons—electron-hole pairs—as a solid-state route to macroscopic quantum coherence, which is useful for quantum technologies. This has been difficult to realize in controllable semiconductor devices because optically generated excitons have very short lifetimes of around a billionth of a second, and BECs are normally attained with ultracold gases in a vacuum. https://phys.org/news/2026-08-quantum-fluid-reveals-hidden-states.html Condensed Matter Tue, 04 Aug 2026 17:40:02 EDT news705076621 Researchers at Flinders University have discovered an unexpected way light can control tiny electronic structures inside advanced materials, a development that could help pave the way for more energy-efficient memory devices, sensors and future computing technologies. https://phys.org/news/2026-08-nanoscale-domains-ferroelectric-crystal.html Condensed Matter Mon, 03 Aug 2026 16:50:01 EDT news704993701 Ruthenium dioxide (RuO2) is a metal oxide that commonly serves as an important metallic conductor, quantum material and industrial electrocatalyst.

In the field of microelectronics—where devices continue to shrink and new materials are introduced—small imperfections in solids can strongly influence how a material stores, transfers or loses energy. Those processes can either be used to improve device performance or create problems such as energy loss, information loss, signal disruption or reduced reliability. https://phys.org/news/2026-07-source-software-energy-tiny-defects.html General Physics Fri, 31 Jul 2026 14:00:06 EDT news704719732 Topological photonics can force propagating light to travel in a single direction—allowing researchers to route optical signals around corners and past defects without any of it scattering backward. So far, however, this one-way flow has only been found at the boundary between two specially engineered "topological insulator" regions, leaving most of the material unavailable for light transport. https://phys.org/news/2026-07-photonic-platform-lane-highway.html Condensed Matter Fri, 31 Jul 2026 10:20:04 EDT news704625165 Semiconductor spin qubits are one of the most promising building blocks for future quantum computers, but turning them into a working, large-scale quantum computer has so far proven difficult. For now, two big questions remain open: how to connect qubits that aren't sitting right next to each other, and how to control huge numbers of them without an unmanageable tangle of wiring. https://phys.org/news/2026-07-independent-semiconductor-qubits-scales.html Condensed Matter Fri, 31 Jul 2026 07:20:04 EDT news704643614 Quantum fluctuations influence direction-dependent electrical transport in chiral magnets, researchers from Science Tokyo report. In chiral magnetic systems, electric current flows differently depending on its direction, but the role of quantum effects in this behavior has remained unclear.
