析自由度、建 Hamiltonian 與狀空、定邊界、擇近似、驗極限。
寫式前全察:
## System Characterization
- **Particles**: [list with quantum numbers]
- **Active degrees of freedom**: [coordinates, spins, fields]
- **Frozen degrees of freedom**: [and justification for freezing]
- **Symmetry group**: [continuous and discrete]
- **Energy scale hierarchy**: [e.g., electronic >> vibrational >> rotational]
得:全目錄(粒、量數、對稱),活凍自由度皆明由。
敗:能階不明→先全留,標須尺度析。早截致質性謬誤。
由一所辨自由度建數學架構:
## Hamiltonian Structure
- **Hilbert space**: [definition and basis]
- **H = T + V decomposition**:
- T = [kinetic terms]
- V = [potential terms, grouped by type]
- **Constants of motion**: [operators commuting with H]
- **Symmetry-adapted basis**: [if block diagonalization is possible]
得:完整 Hermitian H,諸項顯寫,Hilbert 空明,守恆量已辨。
敗:非顯 Hermitian→查漏共軛或規範相。Hilbert 空模糊(如相對論粒)→明形並標問題。
約束使解唯一:
## Boundary and Initial Conditions
- **Spatial domain**: [definition]
- **Boundary type**: [Dirichlet / Neumann / periodic / scattering]
- **Normalization**: [condition]
- **Particle statistics**: [bosonic / fermionic / distinguishable]
- **Initial state** (if time-dependent): [specification]
得:邊界物理合理、與 H 域數學一致,足定唯一解(或明定散射矩陣)。
敗:過定或不足→查 H 於所選域之自伴性。非自伴 H 須處理缺陷指標。
依題構擇解策:
察可精確解:是否歸已知可精解模(諧振子、氫原子、Ising)。若然,主用精解,攝動為校正。
攝動論(弱耦):
變分法(基態):
密度泛函(多電子):
數值精法(小系、基準):
## Approximation Method Selection
- **Method chosen**: [name]
- **Justification**: [why this method fits the problem structure]
- **Expected accuracy**: [order of perturbation, variational bound quality, DFT functional accuracy]
- **Computational cost**: [scaling with system size]
- **Alternatives considered**: [and why they were rejected]
得:擇法有明由,預期精度與算量明,備選亦已錄。
敗:無單法確宜→兩法並立比解。法異揭題難並導進一步精化。
解前驗陳立反映已知:
## Validation Checks
| Check | Expected Result | Status |
|-------|----------------|--------|
| Classical limit (hbar -> 0) | [classical Hamiltonian] | [Pass/Fail] |
| Non-interacting limit | [product states] | [Pass/Fail] |
| Symmetry transformation | [correct representation] | [Pass/Fail] |
| Dimensional analysis | [all terms in energy units] | [Pass/Fail] |
| Known exact case | [reproduced result] | [Pass/Fail] |
得:諸驗皆通。形式自洽,備解。
敗:驗敗乃 H 構建或邊界之誤。溯至該項或條件修之,再進解。
