概要
- 論文の詳細を見る
Spontaneous symmetry breaking in (1+1)-dimensional φ^4 theory is studied with discretized light-front quantization. The critical coupling evaluated from the first few terms in the &plank; expansion of the commutation relations [a_0,a_n] is 28.8μ^2/&plank; ≤ λ_<cr> ≤ 31.1μ^2/&plank;, consistent with the equal-time value, 22μ^2/&plank; ≤ λ_<cr> ≤ 55.5μ^2/&plank;.
