EigenSpace: Quantum Physics 3D

Make the Schrödinger equation visible.

EigenSpace is an interactive quantum mechanics simulator and wavefunction visualizer for Android. Solve quantum eigenvalue problems, navigate energy eigenstates, and examine wavefunctions and probability densities through detailed 2D and 3D visualizations.

Designed for university physics and quantum chemistry students, educators, researchers, and curious learners, EigenSpace connects the potential, energy spectrum, basis composition, wavefunction ψ, and probability density |ψ|² in one touch-friendly workspace. Explore harmonic-oscillator states, hydrogen orbitals, and custom potentials on your phone or tablet.

SOLVE AND EXPLORE

• Configure the solver: choose Cartesian or spherical coordinates, select a basis, and adjust the basis size, particle mass, potential width, and other model parameters.

• Navigate the energy spectrum: move between calculated eigenstates and inspect approximate quantum-number assignments and basis contributions.

• Analyze states in 2D: view wavefunction profiles, probability-density heatmaps, radial distributions, and basis decompositions.

• Explore states in 3D: rotate, zoom, and inspect point-cloud, density-cloud, and isosurface representations.

• Examine interactive slices: position XY, XZ, or YZ planes through a 3D state and view the corresponding 2D probability-density slice.

• Work across devices: use an interface optimized for both phones and tablets.

FREE VERSION

The free version includes the harmonic-oscillator potential and the essential solver and visualization experience. EigenSpace contains no advertising.
