<div dir="ltr">Dear all users<div><br></div><div><br></div><div>I am simulating GNR,with the help of matlab,and in results i am getting self energies in complex forms,can any body tell me if some one has worked in this area,why these broadening as well as self energy matrices are coming in complex forms,or any one has simulated through Quantum Espresso GNR,what kind of shape they have got for conductance ,LDOS .This is the case of without magnetic field term or electric field term,and my hopping terms are simply a number not in terms of vector potential.I am stuck off at this point ,please let me know what else i can do?</div><div><br></div><div>regards</div><div><br></div><div><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div><font size="2">Surender Pratap<br>Research Scholar<br>Physics Department<br>BITS Pilani,Pilani Campus Rajsthan-333031(INDIA)...<br></font></div><font size="2"><font size="2">Mob-<font size="2">7891949445</font></font><br></font><br><div><font color="#990000" face="tahoma, sans-serif"><img src="cid:part1.08000902.09030905@bits-pilani.ac.in"><br></font></div><div><p style="margin-top:6.85pt;margin-right:0cm;margin-left:0cm;margin-bottom:0.0001pt">
