From: Spontaneous formation and relaxation of spin domains in antiferromagnetic spin-1 condensates
Phase | I (mF = 0) | II (mF = ±1) | III (mF = +1) |
|---|---|---|---|
Spin density | m|| = 0 | m|| < ρ | m|| = ρ |
Energy density | \(\frac{{\overline g }}{2}\rho ^2 - q\rho _{}^{}\) | \(\frac{{\overline g }}{2}\rho ^2 + \frac{{g_{\mathrm{s}}}}{2}m_{||}^2\) | \(\frac{{\overline g + g_{\mathrm{s}}}}{2}\rho ^2\) |
Equation of state | \(\mu + q = \overline g \rho\) | \(\mu = \overline g \rho\), η = gsm|| | \(\mu + \eta = ({\bar g} + g_{\mathrm{s}})\rho\) |
