Turbulent Waves Behave like a Gas
• Physics 18, 129
Experiments with turbulent waves show that energy spreads from small to large scales, producing a steady-state regime that can be described using classical thermodynamics.

They glow without fusion—hidden stars that may finally reveal dark matter
The Anglo-USA team behind the study named them dark dwarfs. Not because they are dark bodies — on the contrary — but because of their special link with dark matter, one of the most central topics in current cosmology and astrophysics research….

Physicists Uncover Forgotten 1938 Fusion Breakthrough That Could Power the Future
Physicists confirm DT fusion insights from a 1938 experiment. The findings connect past theory with current fusion efforts. A team at Los Alamos National Laboratory has successfully recreated a significant yet largely overlooked physics…

Low-dimensional compact states in 3D moiré lattices
Geometric properties
We consider a non-interacting BEC having zero s-wave scattering length, which can be achieved by Fesbach resonance, loaded in a quasiperiodic potential V(x). In the mean-field approximation, this system is governed by the…

Two-dimensional Weyl and type-III Dirac semimetals in BaCu monolayer and twisted α/β-BaCu/BN systems
BaCu monolayer
Figure 1a, b illustrates the crystal structure of the single-layer BaCu in side and top views. The monolayer has a lattice constant of a = b ≈ 4.33 Å and belongs to the P6/mmm space group (SG.191), corresponding to the…

A novel approach to salinity monitoring using two dimensional hexagonal photonic crystals
Here, we show the results and optimization procedure of our structure from 2D PCs with a hexagonal unit cell with a triangle lattice. The results are displayed in three parts. In the first part, we study the optical properties of saline water to…

Deep-tissue two-photon brain imaging enabled by a tunable fiber-optic dispersive wave generator
Laser and imaging setup
Guided by the numerical results, an experimental setup is constructed to enable the application of wavelength-tunable DW generation for multicolor deep-tissue two-photon brain imaging. The experimental setup, shown in…

Optimization of connection patterns between mobile phones and base stations using quantum annealing
Naive formulation
In this section, we describe the naive formulation for the problem of maximizing the SINR of each mobile phone when the positions of mobile phones, base stations, and the antenna patterns are fixed. This problem involves…

Methods to achieve near-millisecond energy relaxation and dephasing times for a superconducting transmon qubit
Fabrication
This section provides a detailed description of our sample fabrication process, which is an adaptation of the recipe described in ref. 16 to the chemicals and equipment available to us. Notable differences include the choice of CF4 as…
