The Huang–Yang Formula for the Low‐Density Fermi Gas: Upper Bound
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1919-1972, August 2026.ABSTRACT We study the ground state energy of a gas of spin 1/2$1/2$ fermions with repulsive short‐range interactions. We derive an upper bound that agrees, at low density ϱ$\varrho$, with the Huang–Yang conjecture. The latter captures the first three terms in an asymptotic low‐density expansion, and in particular the Huang–Yang correction term of order

Probing the strongly driven spin-boson model in a superconducting quantum circuit
Nature Communications, 2018 Two-level systems interacting with a bosonic environment appear everywhere in physics. Here, the authors use a superconducting device to study this spin-boson model in the presence of coherent driving, showing that the drive enhances dissipation into the

Protein Science, Volume 35, Issue 7, July 2026.Abstract In light of the centennial of the Schrödinger equation, this article addresses the popular idea that quantum mechanical effects play an important role in biological systems. We start by defining what is qualified as a quantum effect. We then clarify the idea that quantum mechanical tunneling is a crucial factor in enzyme catalysis.

Nanofibrous Bio‐Textile From Tilapia Fish Gelatin Prepared Using Alternating Field Electrospinning
ChemistrySelect, Volume 11, Issue 25, 3 July 2026.Warm‐water fish gelatin nanofibrous nonwovens (W‐FGel “bio‐textile”) are fabricated using alternating field electrospinning (AFES) at productivities up to 5.4 g∙h−1. The average fiber diameter varies in the range of 85 ± 21–240 ± 74 nm depending on the acetic acid–water ratio in the precursor solution.

Electron Scattering in the Interacting Boson Model [PDF]
Il Nuovo Cimento A, 1979 From the preceeding talks two different aspects of the interacting boson model (IBA) of collective degrees of freedom in nuclei have emerged. First the symmetry aspects of the model have been emphasized. It was shown that the Hamiltonian can be expressed in terms of the generators of the SU(6) group, and in special cases in terms of subgroups of SU(6);

Study of Nuclear Structures for Nd 148,150,152 a Isotopes by Using IBM-1
Al-Mustansiriyah Journal of Science, 2018 The nuclear structures of even-even isotopes Nd (A=148,150,152) are studied by using the first Interacting Boson Model (IBM-1). The energy levels of ground state, beta and gamma bands ,energy ratios are calculated. The results showed dynamical symmetry

Noise Spectroscopy of Cavity Polaritons
Advanced Theory and Simulations, Volume 9, Issue 6, June 2026.Advancements in experimental techniques at the nanoscale have given rise to the field of molecular polaritonics. Recent developments report simultaneous measurement of conductance and electroluminescence in such systems. A theoretical method for simulating electron and photon fluxes and noise in open molecular polaritonic systems is formulated by ...

On the Meaning of Localization in Non‐Local Quantum Field Theory
Annalen der Physik, Volume 538, Issue 6, June 2026.In non‐local quantum field theory nature does not necessarily allow objects or events to be localized to exact mathematical points. Instead any physical measurement has a built‐in finite resolution set by the non‐locality scale. Spacetime remains continuous and Lorentz‐covariant, but below this scale pointlike localization becomes an idealization ...

Partial dynamical symmetry and odd-even staggering in deformed nuclei
EPJ Web of Conferences, 2015 Partial dynamical symmetry (PDS) is shown to be relevant for describing the odd-even staggering in the γ-band of 156Gd while retaining solvability and good SU(3) symmetry for the ground and β bands. Several classes of interacting boson model Hamiltonians

Annalen der Physik, Volume 538, Issue 6, June 2026.This study examines slowly rotating traversable wormholes supported by string fluids whose properties change with radius. The matter smoothly shifts from a de Sitter‐like core to a string‐dominated exterior, producing a regular, horizon‐free spacetime.
