Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories — bosons or fermions — but researchers have now shown that bizarre “in-between” particles called anyons could also exist in a one-dimensional system. Even more exciting, these strange particles may be adjustable, allowing scientists to tune the…

For decades, scientists have been searching for quantum spin liquids (QSLs) – materials thought to...

A phonon is absurdly small. The quantum of vibrational energy, the irreducible minimum of sound, it carries no mass and lives only briefly before dissolving back into the thermal noise of whatever material surrounds it. For quantum engineers trying to build the next generation of computing hardware, that brevity has long been the problem. You cannot build an information highway out of something t…

Hi My name is Raymond Russell, I am 61 years old, from Australia, hello everyone. I have a good understanding of physics, the standard model of particle physics, special & general relativity, quantum theory and I like astronomy. Kind Regards Ray

This paper traces a structural intuition across twenty-five centuries of optical inquiry: light is a localized perturbation propagating through a continuous medium that is space itself. The thread runs from the visual rays of Empedocles, through Aristotle's actualization of the transparent, the medieval Latin and Islamic optical traditions, the Newton-Huygens bifurcation, Maxwell's electromagneti…

This paper proves that under a specified mapping from Structural Determination Theory (SDT) to quantum mechanics, the SDT axiom G5 (use exclusivity) implies the no-cloning theorem (Wootters and Zurek 1982; Dieks 1982). The implication is established by showing that any mapping image admitting a universal cloning operator violates G5: the output of cloning, containing two copies of a quantum state…

Scientists have created a new way to generate powerful quantum interactions, achieving the first-ever demonstration of quadsqueezing. This breakthrough makes previously hidden quantum effects visible and usable for advanced technologies. Oxford Scientists Demonstrate First-Ever Quadsqueezing Quantum Interaction Researchers at the University of Oxford have achieved a major advance in quantum physi…

algebraic quantum field theory (perturbative, on curved spacetimes, homotopical) quantum mechanical system, quantum probability interacting field quantization DHR superselection theory is about superselection sectors in the Haag-Kastler approach to AQFT. As such, it has to state one or more conditions on representations of the given Haag-Kastler net that specify the representations of the quasi-l…

The Problem of Time — the apparent incompatibility between quantum mechanics' time parameter t and general relativity's proper time τ — has been treated as a fundamental obstacle to quantum gravity. This paper argues that the apparent incompatibility is the joint product of a level-confusion: both theories define time within their own entity-theoretic frameworks, generating an apparent opposition…

Nature Communications, Published online: 08 May 2026; doi:10.1038/s41467-026-71789-y Nonreciprocal magneto-transport is often attributed to Zeeman-driven mechanisms. Here, the authors identify Lorentz skew scattering nonreciprocal magneto-transport in BiTeBr which emerges from the cooperation of classical Lorentz force and quantum skew scattering.

_Zenodo_. 2026This paper presents a non-modal fixation of quantum. Quantum is not treated as probability, uncertainty, or measurement. It is fixed without causality, temporality, or subject-dependent interpretation. The paper does not explain quantum. It delimits the conditions under which quantum is fixed. This paper belongs to the Readable Configuration Series I. ( direct link )

Quantum 10, 2099 (2026). https://doi.org/10.22331/q-2026-05-08-2099 Current and near-term quantum hardware is constrained by limited qubit counts, circuit depth, and the high cost of repeated measurements. We address these challenges for solid-state Hamiltonians by introducing a logarithmic-qubit encoding that maps a system with $N$ physical sites onto only $\lceil \log_2 N \rceil$ qubits while m…

In a process analogous to how solids melt into liquids, the electrons in many different metals form crystal-like patterns that can deform and melt, opening new pathways for neuromorphic computing and superconductors, University of Michigan Engineering researchers have found.

Abstract Experiments in a dispersion-engineered nanophotonic lithium niobate waveguide have demonstrated two-color soliton compression to few-cycle duration by exploiting cascaded second-order nonlinearity. These results open new opportunities to study quadratic soliton dynamics in integrated platforms and for applications in on-chip photonic signal processing.

Abstract Context Alloyed core/shell quantum dots (QDs) provide a platform for composition-controlled modulation of electronic structure and optical response. Using an integrated extended tight binding (xTB) and simplified Tamm Dancoff approximation (sTDA) framework, a composition-defined GaInZnP/ZnSe y S 1-y core/shell QD series ( y = 0.00, 0.25, 0.50, 0.75, 1.00) revealed a distinctly nonlinear …

We investigate the thermodynamic criticality and phase structure of dilaton black holes in the presence of Born-Infeld nonlinear electrodynamics and a Liouville-type potential. By adopting an analytical approach based on the near-horizon geometry and the first law of thermodynamics, we derive consistent expressions for temperature, entropy, charge, and mass. This method allows us to bypass the co…
