Researchers achieve first quantum simulation of baryons
A team of researchers led by an Institute for Quantum Computing (IQC) faculty member performed the first-ever simulation of baryons—fundamental quantum particles—on a quantum computer.

Strengthening the second law of thermodynamics
According to the second law of thermodynamics, the total entropy of a closed process can increase or stay the same, but never decrease. The second law guarantees, for example, that an egg can wobble off a table and leave a mess on the floor but that such a mess will never spontaneously form an egg and leap back on the table. Or that air will escape a balloon but never, on its own accord, inflate it. Since at least the 19th century, physicists have been investigating the role of entropy in information theory—studying the energy transactions of adding or erasing bits from computers, for example.

CMS collaboration has observed three J/ψ particles emerging from a single collision between two protons
It's a triple treat. By sifting through data from particle collisions at the Large Hadron Collider (LHC), the CMS collaboration has seen not one, not two but three J/ψ particles emerging from a single collision between two protons. In addition to being a first for particle physics, the observation opens a new window into how quarks and gluons are distributed inside the proton.

Amount of information in visible universe quantified
Researchers have long suspected a connection between information and the physical universe, with various paradoxes and thought experiments used to explore how or why information could be encoded in physical matter. The digital age propelled this field of study, suggesting that solving these research questions could have tangible applications across multiple branches of physics and computing.

Analysis puts most general constraints on nonstandard neutrino interactions
For decades, physicists have theorized that the current best theory describing particle physics—the "Standard Model"—was not sufficient to explain the way the universe works. In the search for physics beyond the Standard Model (BSM), elusive particles called neutrinos might point the way.

Why skyrmions could have a lot in common with glass and high-temperature superconductors
Scientists have known for a long time that magnetism is created by the spins of electrons lining up in certain ways. But about a decade ago, they discovered another astonishing layer of complexity in magnetic materials: Under the right conditions, these spins can form little vortexes or whirlpools that act like particles and move around independently of the atoms that spawned them.

Quantum circuit black hole lasers to explore Hawking radiation
The fundamental forces of physics govern the matter comprising the universe, yet exactly how these forces work together is still not fully understood. The existence of Hawking radiation—the particle emission from near black holes—indicates that general relativity and quantum mechanics must cooperate. But directly observing Hawking radiation from a black hole is nearly impossible due to the background noise of the universe, so how can researchers study it to better understand how the forces interact and integrate into a "Theory of Everything?"

Researchers announce photon-phonon breakthrough
New research by a City College of New York team has uncovered a novel way to combine two different states of matter. For one of the first times, topological photons—light—has been combined with lattice vibrations, also known as phonons, to manipulate their propagation in a robust and controllable way.
