Target models

Six decades from its inception¹, the FH model remains intensely studied because it contains very few physical degrees of freedom, yet it captures salient features of strongly correlated electronic systems. Despite the attention it…

Mathematical design of TPMS structures

Primitive, Gyroid and Diamond surfaces can be described by the following equations given in Table 1. The function f(x, y, z) is and iso-surface evaluated at an iso-value C. The space is separated by the TPMS…

Our experimental setup is depicted in Fig. 1. The photoelectric control system is shown in Fig. 1a. A semiconductor laser (EYP-DFB-0795-00080-1500-BFW01-0005, TOPTICA) is used as the source. About 0.5 mW laser power is feed into the frequency…

Heterogeneous ice nucleation and growth

By the in-situ cryo-TEM equipped with high-resolution real-time and real-space imaging (see “Methods”), we investigated the microdynamics of ice I formation from vapor deposition on translucent graphene…

Here, we utilized the present technique for solving the time-fractional improved (2+1)-dimensional nonlinear Schrödinger equation with the presence of the spatio-temporal dispersions, which enables us to obtain optical solutions with diverse…

Heisenberg Hamiltonian

We begin our study of spangolite by determining the parameters of the Heisenberg Hamiltonian

using the density…

Materials and reagents

Unless otherwise noted, all compounds, chemicals and solvents were purchased from Sigma-Aldrich (St. Louis, MO, USA) or Bracco Imaging (Colleretto Giacossa, Italy).

Multi-resolution hash encoding

The hash encoding \({\mathcal{H}}\phi\) operates across L resolution levels, with each level maintaining a dedicated table of feature vectors⁴¹. For each level l, input coordinates are mapped to grid vertices…
