[Pw_forum] SOC with Spin Polarization (UP and DOWN SPIN)

2017-01-27 Thread Mohammed Ghadiyali
Thanks, Federico for the reply. I do understand that when SOC is used than spin polarization is not considered. But that's the problem the paper which I 'm referring does talk about it and do provide the information regarding the spin polarization, in the paper "Valence Band Splitting on M

just typing "carbon nanotube position generator” in google I found for example: http://www.nanotube.msu.edu/tubeASP/ it does not give the unit cell period (c in the example I sent you), but it is enough to generate two unit cells to guess it. Giovanni >

a CNT is represented, within QE, with the supercell approach, for example you choose a tetragonal cell, with z axis as a periodicity direction and x and y axes where vacuum space is added to the lattice parameter(s) to prevent periodi replicas to interact with each other. The positions of the C

hi is there any example to compute scf and nscf calculations of any kind of simple Carbon nanotube in QE. If there is any archive then please suggest how to construct a simple CNT in QE. -- Uttam Paliwal *Assistant Professor* Department of Physics J.N.V. University Jodhpur (India) Phone- 759790844

Hi. Normally when do you introduce SOC you loose the common polarization UP and DOWN for the spin. Thou it does not make sense anymore talking about spin up and spin down. Thou for a SOC in QE, you have to specify only noncolin=.true. and lspinorb=.true. paying attention to use a proper rela
