A Photonic Molecule built from three coupled whispering-gallery resonators. A guided electromagnetic pulse enters through the bus waveguide, loads into the first ring, tunnels onto the second, then climbs knto the third through evanescent coupling. Simulated directly with Maxwell's equation using FDTD.

Fantastic work. Inspiring. I recently implemented a Maxwell EM visualizer. Here you can see the E feel oscillating, and I’ve got a Navier Stokes solver driving a particle field that shows the realistic orthogonal oscillation of the M field. This visualization solves for the stapled poles did not require FDTD. I’ve since implemented FTDT solver. It’s all using Rust/wgpu. You’ve taken it to the next level though. I’m interested to know what made you think of doing this at all.

is the first to second to third loading sequence set by the coupling topology alone, or did you detune the resonances and time the input pulse to produce it?

That visual is a perfect showcase of the interactions of the Miller-Turner Triad. I recently wrote three papers covering it.

Beautiful work 👏 Ring resonators like these already sit at the heart of on-chip optical communications. I'm curious what coupling coefficients you used between rings. #Photonics #FDTD

This is an animation of a Photonic Molecule. Light becomes trapped inside a tiny ring and then coupled into another without the two ever touching. The scene is evolved from Maxwell's equations using Finite Difference Time Domain (FDTD) on a dense Yee grid.

A sharp 90-degree turn is a brutal request for an Electromagnetic wave. Yet inside a Photonic Crystal, something remarkable can happen. The repeating dielectric structure creates ranges of frequency for which propagation through the bulk crystal is strongly suppressed. Remove a line of that crystal and suddenly the defect becomes an allowed route the EM field.

A Luneburg lens bends an Electromagnetic wave without a curved boundary. Instead its dielectric constant changes continuously from the centre to the edge. This forces different parts of the wavelength to travel at different speeds. Here, we solve the full 2D TM EM wave equation on an unstructured triangular mesh using the Finite Element Method (FEM).

The Probability Density of a Brownian Particle Solves the. Heat Equation. Einstein’s 1905 paper on Brownian motion doesn’t get the same spotlight as General Relativity, but it’s still an astonishing piece of work. It takes a messy, noisy phenomenon and extracts three hard facts from it: First, the randomness of the particles is physical. The motion is molecular impacts made visible. Second, one path looks like chaos, but the cloud has a rigid scaling law...mean-square displacement grows like t, so the width grows like √t. Third, the cloud evolves deterministically. Its density solves the heat equation PDE! So Brownian probability spreads the same way heat spreads!

A Hamiltonian system is a way of describing motion where position and momentum evolve together as one coupled system. The plot shows an energy landscape in phase space, with the motion of the system traced directly on top of it and projected onto the underlying phase portrait. #HamiltonianSystems #PhaseSpace #PhysicsSimulation #DynamicalSystems #MathematicalPhysics

Erwin Schrödinger’s 1926 equation changed the game by turning Quantum Mechanics into wave dynamics. That move gave Physics a new way to think. Instead of forcing a particle onto one sharp path, it lets a complex wavefunction evolve in time, with its shape and phase holding the structure of the phenomenon. What makes this so striking is that Schrödinger’s equation does not start from vague mystery. It starts from a precise and daring idea The state of a particle is a complex field ψ(x,t), and the dynamics must push ψ forward in a way that preserves total probability.

A Bonus render of Electron Holography for our Quantum Mechanics Lecture Series. We’re staging a TEM-style electron holography shot as a single 3D scene. A coherent electron wave ψ(x,y,t) enters from the left as a localized packet, gets split by a thin biprism phase wedge, then bends around a central nanoring that stands in for an enclosed magnetic flux. The wave evolves by Schrödinger dynamics, so its intensity ρ=|ψ|² is literally the electron detection probability density, while the probability current j=(1/m)Im(ψ*∇ψ) acts like a conserved flow of that density across the plane. The main surface is a living whose height tracks |ψ| and whose skin color cycles with arg(ψ). On top of it, luminous current ribbons trace streamlines of v=j/(ρ+ε), so you can see how phase gradients steer the flow around the ring and back into interference. High above, a tilted detector/hologram screen shows the off-axis fringe image you’d measure (intensity after mixing with a reference wave), while a porcelain bead marks the centroid ⟨x⟩(t) and flux threads through the ring pulse in sync with the Aharonov-Bohm phase knob φ_AB(t). See our lecture series for details. #QuantumMechanics #ElectronHolography #MathematicalPhysics #Physics

Have You Ever Heard of Molecular Communication Systems? Instead of using radio waves or light, molecular communications send information carefully through released chemical particles. A transmitter emits molecules into a medium, the channel reshapes that signal through diffusion, flow, and randomness. The receiver reads the message from the molecules that arrive and bind. It is communication theory at microscopic scale, where physics, probability and biology all become part of the channel. Some applications you may know: Targeted drug delivery inside the body, microscopic health monitoring with nanosensors, and lab-on-a-chip.

General Relativity allows a geometry where two distant regions of Spacetime become connected through a curved throat. In 1935, Albert Einstein and Nathan Rosen showed that the Schwarzschild solution can be extended into a bridge-like structure. The metric is ds² = −(1 − 2M/r)dt² + (1 − 2M/r)⁻¹dr² + r²dΩ² Under maximal coordinate extension, the Spacetime splits into two asymptotically flat regions joined through a narrow throat called, the Einstein–Rosen bridge. It's a geometric structure emerging directly from Einstein’s field equations. #EinsteinRosenBridge #GeneralRelativity #SpacetimeGeometry #BlackHolePhysics #EinsteinFieldEquations #Relativity

Hezbollah’s ATGM team locked onto the Blat al-Mustahad ridge, tracked the zionist position through its routine movement cycle, then burned the emplacement in a single guided strike. The aftermath shows one soldier crawling back into the blast zone to drag the wounded. A clean hit, full disruption on the crest.
