I never knew i needed a strawberry shortcake au until i read your fic oml it was so nice :""")

I DIDN’T REALISE EXACTLY HOW BORDERLINE CRACK IT WAS UNTIL AFTER ZEE READ IT AND SAID SHE WAS PROUD OF ME..... a bitch might have wept >>

But thank you so much! I’m glad you enjoyed it babe!!! Thank you for reading and taking the time to send this!! ❤️💘❤️💖💝

Using DFT Quantum Computing To Reveal Atomic Secrets

DFT Quantum Computing Density Functional Theory: Advance Science at the Atomic Scale Quantum mechanical modelling with Density Functional Theory (DFT) is revolutionising our understanding of atoms and materials in physics, chemistry, and materials. This innovative method examines the ground state and electronic structure of many-body systems like atoms, molecules, and condensed phases using spatially dependent electron density instead of electrons. Because of its versatility and low processing cost compared to Hartree-Fock theory, it is prized for scientific inquiry and technological growth.

DFT's theoretical journey began in 1927 with the Thomas–Fermi model, which computed atomic energy using kinetic-energy functional and classical interactions and represented electron distribution with a statistical model. It was a major initial step, but imprecise kinetic and exchange energy representations and a complete disregard for electron correlation limited its precision when Paul Dirac provided an exchange-energy functional in 1928. In the middle of the 1960s, Walter Kohn and Pierre Hohenberg discovered the two Hohenberg–Kohn theorems (HK), which established DFT theoretically. Theorem 1 states that only a three-dimensional electron density can determine a many-electron system's ground-state features. This basic realisation used electron density functionals to simplify the many-body problem from 3N spatial coordinates for N electrons to three. It also indicates that the external potential, many-body wavefunction, and Hamiltonian spectrum are all unique functions of the ground-state density. Theorem 2 develops an energy functional and proves that the ground-state electron density minimises the Hamiltonian's energy content at the real ground-state charge density.

Florida Develops Quantum Computing in Palm Beach County. Walter Kohn and Lu Jeu Sham expanded on the HK theorems to produce Kohn–Sham DFT (KS DFT), a framework that made non-interacting electrons moving in an effective potential controllable. The effective potential contains the external potential and electron-to-electron Coulomb, exchange, and correlation interactions. Kohn-Sham equations, n-electron Schrödinger-like equations, are used to examine electronic structure. An iterative, self-consistent approach computes the effective potential, solves for orbitals, and produces a new density until convergence is reached to solve these equations. KS DFT frequently encounters the exchange and correlation functionals' unknown exact forms, except for the free-electron gas. This led to several approximations: The Local-Density Approximation (LDA) is the simplest because it assumes the functional depends only on density at the evaluation site. Although LDA may account for these errors, it often overestimates correlation energy and underestimates exchange.

Local Spin-Density Approximation (LSDA) generalises spin. GGAs account for electron density non-homogeneity by expanding in terms of the density's gradient. GGA functionals like the BLYP and updated Perdew–Burke–Ernzerhof (PBE) have yielded good ground-state energy and molecular geometries. Meta-GGA Functionals: These more advanced functionals incorporate the second derivative (Laplacian) of the electron density in addition to the density and its first derivative. Hybrid Functionals: The popular B3LYP improves precision by incorporating a component of Hartree-Fock theory's precise exchange energy. Others argue that they use adjustable parameters fitted to “training sets” of molecules, which detracts from the search for the precise functional and potentially weaken the second DFT theorem. DFT has been expanded to handle more complex circumstances. Particularly for hydrogen-like ions that meet the Dirac equation, a relativistic formulation for relativistic electrons allows exact and explicit density functionals. For systems in magnetic fields, CDFT and BDFT add the magnetic field or paramagnetic current density to the functionals. However, developing usable functionals beyond LDA equivalents is difficult. DFT has many and developing uses. Since the 1970s, solid-state physics has relied on DFT to understand crystal electric field gradients, especially for Mössbauer spectroscopy. With better exchange and correlation approximations, quantum chemistry precision improved in the 1990s. DFT is often used in: Materials science: Dopant effects on phase shifts, material behaviour prediction, and magnetic and electronic behaviour in various materials are examples of materials science. Chemistry: Characterising and predicting biomolecules, chemical processes, and novel molecules. Nanotechnology predicted coating mechanical properties and nanostructure contaminant sensitivity. Electronic devices: Studying complex molecules, amorphous and crystalline materials, interfaces, and atomic-scale devices' electronic, thermal, mechanical, optical, magnetic, ferroelectric, and thermoelectric properties, especially with non-equilibrium Green's functions (NEGF).

Because of its predictive capability, DFT can handle practically any element and atomic arrangement without experimental input, making it a potent technology pathfinding tool. This lets researchers study new materials and phenomena years before they're made. Synopsys offers systems like QuantumATK, which integrates DFT and other models (force fields, semiempirical models, and machine learning) to provide atomistic modelling for complex materials and device designs. However, DFT has limitations. It can struggle to represent transition states, charge transfer excitations, intermolecular interactions (especially van der Waals forces), and highly coupled systems. Its poor dispersion force handling may also hamper accuracy in dispersion-dominated systems. Some alterations “stray from the path towards the exact functional” while functionals are developed. The conventional DFT technique has trouble estimating computation errors without external comparison. Traditional Density Functional Theory (CDFT) is used to examine interacting molecules, macromolecules, and microparticles individually. It uses a formalism similar to quantum DFT to calculate modifications of a spatially dependent thermodynamic functional of particle density. CDFT is essential for studying fluid phase transitions, liquid ordering, and nanomaterial properties since it is computationally cheaper than molecular dynamics simulations for larger systems and longer timescales. Chemistry, civil engineering, biophysics, and materials science use it. Density Functional Theory has revolutionised atomic-level quantum world research due to its profound theoretical roots and ongoing approximation development. In many scientific and technical fields, new methods, processing power, and integrations with machine learning promise more improvements.

THE GIRLS!!!

(I worked on this manuscript for the first time in months and rewarded myself.)

Here we have: the four crew stuck on a space ship with a broken jump drive, a glitchy AI, and 6 award-winning jr. high students.

top left to bottom right:

Kelly, Captain, who I directly lifted from a dear captain friend IRL and will probably have to rename. Extremely smol. Extremely competent. Can do a lot of pull-ups.

Damaris, first officer. Lesbian soccer star you had a crush on. Wears basketball shorts in space. Endless depths of patience but also won’t put up with nonsense and notices everything. Has something going on with Linny??? they’re just good friends Geneva is just ace and bad at reading such things

Geneva, Program coordinator. My daughter. My poor, stressed child. Ex-military and good with kids but not entirely sure how to do both at the same time? Must be forced to trust herself. The main character.

Linny, Engineer. Disaster bi, sarcastic and grumpy. Why are you even working with kids??? You could be paid 5x this if you just went back to building rocket engines Linny. Lab queen, mean to Geneva but she’ll come around. The kids are in awe of her.
