<div dir="ltr">Dear wien2k users,<div><br></div><div> I have simulated properties of one titanate based oxide materials with GGA+U. The structure contains 56 inequivalent atoms. The simulated properties are well confronted with experimental properties. However, while the optimized structure obtained with GGA+U is used to simulate electronic structure with mbj potential, ghostband error arises for p orbital of one of the oxygen atom of the compound. Can anybody figure out the possible cause for this error?</div><div><br></div><div>Computational parameters are: Rmt*Kmax=7, K-points=14, Port mixing scheme with mixing parameter 0.2. However, even after decreasing the mixing parameter to 0.05 the same error appears for another oxygen atom of the structure.</div><div><br></div><div>Thanks in advance.</div><div><br></div><div>with regards, <br clear="all"><div><br></div>-- <br><div class="gmail_signature">Shamik Chakrabarti<br>Senior Research Fellow<br>Dept. of Physics & Meteorology<br>Material Processing & Solid State Ionics Lab<br>IIT Kharagpur<br>Kharagpur 721302<br>INDIA</div>
