Tiny solid particles—like pollutants, cloud droplets and medicine powders—form highly concentrated clusters in turbulent environments like smokestacks, clouds and pharmaceutical mixers.

The operation of quantum computers, systems that process information leveraging quantum mechanical effects, relies on the implementation of quantum logic gates. These are essentially operations that manipulate qubits, units of information that can exist in a superposition of states and can become entangled.

Copper selenide (Cu₂Se) attracts scientific interest for its thermoelectric ability to convert heat into electricity, but a lack of atomic-level understanding has limited its practical applications for decades.

Researchers from Japan have discovered a unique Hall effect resulting from deflection of electrons due to “in-plane magnetization” of ferromagnetic oxide films (SrRuO3). Arising from the spontaneous coupling of spin-orbit magnetization within SrRuO3 films, the effect overturns the century-old assumption that only out-of-plane magnetization can trigger the Hall effect.

Caltech scientists have developed an artificial intelligence (AI)–based method that dramatically speeds up calculations of the quantum interactions that take place in materials. In new work, the group focuses on interactions among atomic vibrations, or phonons—interactions that govern a wide range of material properties, including heat transport, thermal expansion, and phase transitions. The new machine […]

Quantum computing promises to solve the seemingly unsolvable in fields such as physics, medicine, cryptography and more.

This is what fun looks like for a particular set of theoretical chemists driven to solve extremely difficult problems: Deciding whether the electromagnetic fields in molecular polaritons should be treated classically or quantum mechanically.

Cornell Engineering researchers have demonstrated that, by zapping a synthetic thin film with ultrafast pulses of low-frequency infrared light, they can cause its lattice to atomically expand and contract billions of times per second—strain-driven “breathing” that could potentially be harnessed to quickly switch a material’s electronic, magnetic or optical properties on and off.
