超导宇宙弦中的Shock waves:电流的增长

Shock waves in superconducting cosmic strings: growth of current

Ernst Trojan, George V. Vlasov

摘要:

超导宇宙弦的内禀运动方程可能有激波形式的解,这意味着电流项χ的不连续性。不连续超曲面以有限增量Δχ=χ + -χ-确定的有限速度传播。在稳定的冲击波中,电流增加χ +>χ-,但类空电流(χ>0)和类时电流(χ<0)之间的转换是不可能的。

英文摘要:

Intrinsic equations of motion of superconducting cosmic string may admit solutions in the shock-wave form that implies discontinuity of the current term χ. The hypersurface of discontinuity propagates at finite velocity determined by finite increment Δχ=χ_+ -χ_-. The current increases χ_+>χ_- in stable shocks but transition between spacelike (χ>0) and timelike (χ<0) currents is impossible.
