Does cp2k have r2SCAN built in? What other open source quantum codes …
Yes, CP2K has r²SCAN (often written as r2SCAN) built-in via its integration with LibXC. It supports the full r²SCAN functional (by specifying separate exchange and correlation components, e.g., MGGA_X_R2SCAN and MGGA_C_R2SCAN), as well as variants like r2SCAN hybrids (e.g., r2SCANh, r2SCAN0) and deorbitalized forms (r2SCAN-L). CP2K is fully capable of periodic unit cell calculations and ab initio molecular dynamics (AIMD).
