Hi all,
I'm attempting to look at spin correlation functions, both nearest neighbour and next nearest neighbour, near the centre of an XXZ chain that is undergoing a quench using the TEBD code. As far as I can tell from the documentation, these measurements are hardcoded in to the TEBD code, but the documentation gives no clue on how to access them. In effect, what I would like to know is what can I write into the following line of Python (taken from the second TEBD tutorial): Data = pyalps.load.loadTimeEvolution(pyalps.getResultFiles(prefix='tutorial_2a'), measurements=['Local Magnetization']) instead of 'Local Magnetization', in order to obtain the correlation functions, and also how I could then define which sites the correlation function will be calculated using. I think a question similar to this was asked in January, but there was no answer.
Thank you very much in advance! Joseph Prentice
