Hi Everyone, As part of my computational project in topological insulators, I wish to calculate the Z2 invariant in my tight binding model of Kane-Mele Graphene. I have so far produced band structure and surface states consistent with literature, and have been looking at the theory of the Z2...

Hi all, I'm currently trying to investigate the edge current on a finite strip of Zigzag Haldane model (spinless, pi/2 phase) and I measure the current (in my code) by taking the expectation value of my current operator which is a function of wavevector k, for each eigenvector of the...

Thanks man, How far into your project were you? Who did you speak to (what position in admin) to change? It just feels like I've wasted so much effort on what will in the end be for nothing.

Hey, I'm having a big problem with my master's (MSci) project, in the sense that there isn't one! My supervisor doesn't actually know what he's going to arrange as a project yet and its been a month into it, and he doesn't seem to offer any helpful insight. He keeps asking if I have any ideas...

Hi all, I'm currently applying for PhD/CDT positions, and I have one reference who is a great Professor who like has his own significant theorem and let's me know when they've come and tells me to pester him to send them. The other is an Professor in America (I'm in the UK) whose obscenely...

Hi, I'm in a similar boat as I would very much like to pursue a PhD at the same university I am at now (Imperial) as the department of condensed matter physics is really active and I wouldn't have to spend much time organizing the programme beforehand or adjusting to a new university at the...

I only just started reading about QFT and partially the Dirac Equation, but I thought that in a wave solution of the Klein Gordon (which is also a solution of Dirac Eq.), in the complex exponential of the Lorentz invariant quantity pμxμ, the negative energy was accounted for by Feynman by...

My next year gives me the Undergraduate Masters that is quite common in the UK. Also my project choice wouldn't be so narrow, as I wouldn't mind a project where I get to study various other aspects of theoretical solid state and the interaction of radiation with matter. I'm looking for quite a...

I am quite set on remaining in the UK for my PhD, and was mainly looking at Cambridge and Manchester's CMT groups, or thinking of staying on at Imperial. I get quite homesick and also wasn't interested in doing a GRE test. I'm currently doing a Summer project on Majorana Fermions in Thin film...

Hi All, I'm very close to having to start thinking about what and where my PhD will involve. I'm interested in Theoretical Condensed Matter, (possibly topological superconductors/insulators ) and was just wondering if anyone knows from experience which universities have very active research...
