The electronic structure of 1/1 ZnMgHf and its consequences for the electronic transport of the quasicrystal
Structural relaxation
The structure after relaxation has a lattice constant equal to 14.3185 Å for B1 and 14.3004 Å for T1. This value is almost 5% greater than the experimentally determined value 13.6740 . With the GGA, the overestimation of…

Modeling the impact of intercellular signaling on dose metrics and therapeutic outcomes in spatially fractionated radiation therapy (SFRT) for lung cancer
Patient selection and contouring
From the patient population at Imam Khomeini Hospital’s Cancer Institute, a lung cancer patient with a GTV of 875.310 cm3 was retrospectively selected. This study was conducted using anonymized CT scan images,…

Universal quantum computation using Ising anyons from a non-semisimple topological quantum field theory
Non-semisimple anyons
The fusion rules governing anyons in our theory are closely related to SU(2)k Chern-Simons theory at level k = 2, in which each quasiparticle has a half-integer “q-deformed” spin quantum number, or q-spin, analogous to…

Observation of a bilayer superfluid with interlayer coherence
Monte Carlo simulation
We use classical Monte Carlo simulations to obtain the many-body thermal state of our interacting system at nonzero temperature. To perform these simulations, we discretize real space on a 2D square lattice and represent the…

Foundation neural-networks quantum states as a unified Ansatz for multiple hamiltonians
Theoretical framework
The first step in developing foundation models to approximate ground states of quantum many-body Hamiltonians is to establish a theoretical framework that enables training a single NQS to approximate the ground states of…

Defected ground structure antenna array with metasurface inspired interlinked CSRR for 5G millimeter wave applications
The design of the antenna array began with the selection of the Rogers RT5880 substrate, chosen for its favorable electromagnetic properties, including a dielectric constant (εr = 2.2), a low loss tangent (tanδ = 0.0009), and a…

Attosecond spectroscopy of molecular charge transfer uncovers a 1.5-fs delay in population transfer
To investigate the effect that a third (intermediate) state has on the dynamics of a two-state crossing we introduce the following model Hamiltonian, which depends on a reaction coordinate x:
