About v0.2-qm

From Exam Tool to Quantum Mechanics Assistant

v0.1-qm validated the full pipeline of textbook distillation and local deployment. v0.2-qm builds on that foundation with a stronger base model and cloud API service, preserving exam focus while expanding into daily learning, concept clarification, and derivation assistance.

🎯

Exam-Oriented

Targets high-frequency final exam topics: concept explanation, formula derivation, calculation problems, and proof questions.

💬

General Q&A

Not limited to exam questions; also explains concepts, compares representations, and discusses physical pictures and common misconceptions.

⚡

Cloud API

Call via the DashScope OpenAI-compatible endpoint. No local GPU required; just apply for an API Key to get started.

🚀

Stronger Base Model

Powered by Qwen2.5-7B-Instruct for significantly improved reasoning and instruction following, with more stable and well-formatted responses.

Features

What v0.2-qm Can Do

Concept Explanation

Explains core concepts such as wave functions, the uncertainty principle, representation transformations, identical particles, spin, and entanglement in clear language.

What is a Hermitian operator?

A Hermitian operator satisfies A† = A, has real eigenvalues, and corresponds to physical observables...

Formula Derivation

Step-by-step derivations of the Schrödinger equation, ladder operators, angular momentum commutation relations, perturbation theory, and more.

Exercise Solving

Provides problem-solving strategies and step-by-step solutions for harmonic oscillators, hydrogen atoms, perturbation theory, and scattering.

General Quantum Q&A

Answers open-ended quantum mechanics questions, including physical pictures, comparisons of theoretical frameworks, and connections to frontiers.

OpenAI-Compatible API

Uses the standard OpenAI SDK format, lowering integration costs and making it easy to embed in learning tools or teaching platforms.

Explain the energy level formula for a 1D infinite potential well.

⚛️

For a 1D infinite potential well of width a, solving the time-independent Schrödinger equation gives:

E_n = (n²π²ℏ²)/(2ma²), n = 1, 2, 3, ...

Key points:

Energy is quantized, not continuous.
The ground-state energy is non-zero (zero-point energy).
Energy scales inversely with a²: the narrower the well, the higher the energy.
