Detecting quantum chaos via pseudo-entropy

Journal of High Energy Physics
Quantum informatic quantities such as entanglement entropy are useful in detecting quantum phase transitions. Recently, a new entanglement measure called pseudo-entropy was proposed which is a generalization of the more well-known entanglement entropy ...

Hybrid Deference, Hybrid Chance

Philosophy and Phenomenological Research, Volume 112, Issue 1, Page 214-233, January 2026.
ABSTRACT If you learn about one kind of chance and nothing else, then you should defer to those chances. But what if you learn about more than one kind of chance? In such “hybrid” cases, familiar chance‐credence principles, like the Principal Principle, go silent when they should intuitively speak.

Thermal chaos of quantum-corrected-AdS black hole in the extended phase space

European Physical Journal C: Particles and Fields
We briefly analyzed the equation of state and critical points of the quantum-corrected-AdS black hole and used the Melnikov method to study its thermal chaotic behavior in the extended phase space of flat, closed, and open universes.

Splitting the difference: Computations of the Reynolds operator in classical invariant theory

Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract If G$G$ is a linearly reductive group acting rationally on a polynomial ring S$S$, then the inclusion SG↪S$S^{G} \hookrightarrow S$ possesses a unique G$G$‐equivariant splitting, called the Reynolds operator. We describe algorithms for computing the Reynolds operator for the classical actions as in Weyl's book.

Fuzzy spheres in stringy matrix models: quantifying chaos in a mixed phase space

Journal of High Energy Physics
We consider a truncation of the BMN matrix model to a configuration of two fuzzy spheres, described by two coupled non-linear oscillators dependent on the mass parameter μ.

Quantitative Treatments for Explaining the Mechanism and Kinetics of Catalytic Electron Transfers in Murburn Processes, Particularly Involving Heme Enzymes Like (Per)oxidases and P450s

BioMed Research International, Volume 2026, Issue 1, 2026.
The seminal Michaelis–Menten theorization for biological catalysis was based on “transition state” (TS), involving the formation of a topologically complementary substrate (S) and enzyme (E) complex (ES) at the “active site” of the latter. Rudolph Marcus put forth the theory of outer sphere electron transfer (ET) in a “donor–acceptor” TS complex, which

The Dynamical Landscape of the Negative‐Order (3+1)‐Dimensional Calogero–Bogoyavlenskii–Schiff Equation

Journal of Mathematics, Volume 2026, Issue 1, 2026.
A new negative‐order form of the (3 + 1)‐dimensional Calogero–Bogoyavlenskii–Schiff equation is examined in this investigation. This equation plays an important role in accurately describing the thermodynamic properties of mixtures, particularly in chemical engineering applications.

A Secure and Robust Blockchain‐Based Medical Image Encryption Approach Using Lorenz Chaotic System

Journal of Sensors, Volume 2026, Issue 1, 2026.
Keeping medical images confidential while transmitting is crucial, especially in an open networking environment. One effective approach is blockchain‐based encryption, which provides strong security for sensitive healthcare data. To ensure the greatest levels of medical data integrity and authenticity, our proposed scheme employs a unique Lorenz ...

Simulating quantum chaos without chaos

Quantum chaos is a quantum many-body phenomenon that is associated with a number of intricate properties, such as level repulsion in energy spectra or distinct scalings of out-of-time ordered correlation functions. In this work, we introduce a novel class of "pseudochaotic" quantum Hamiltonians that fundamentally challenges the conventional ...
