    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

    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

    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

    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:

    Sub-nanosecond polarization switching with anomalous kinetics in vdW ferroelectric WTe2

    Characterizations of ferroelectricity in WTe2

    WTe2 exhibits various crystal structures, such as 2H, 1T’, and Td. In the Td phase (Td-WTe2, space group Pnm21), the tungsten (W) atoms are surrounded by octahedra formed by…
