Hey, There are really only two people that decide whether you're given an offer, the head of the group and the supervisor. Once they decide they would like to make you an offer they make the suggestion to the Board of Graduate studies. If the supervisor wants to make you an offer the BoGS...

Hi, Yeah my interview was a few years ago, in fact I'm finishing my thesis off right now. I'm apart of the Semiconductor physics. I wouldn't worry about the interview at all, they're more interested in getting to know the student's interests. You'll be given a tour of each group and meet with...

You can create entanglement through interference effects. Also it isn't necessary that the photon pair are emitted by the same source ss long as the which-path information is erased.

yes i think i need to do that , i'll try that and get back to you

Because I know what the final answer should be and it is just a single expression so it should be possible to have a single expression for the simplified form in post #1

I understand that but how do I obtain a general expression for the limits when a and b are independent of each other?

Hurkyl yes that's correct, as for a and b they can take any real value and are not dependent on each other. The function that I posted at the beginning is part of a larger function that I want to eventually plot as a function of a and b. x in this case is like a dummy variable over which I...

I know, but this lower limit I'm trying to find would vary depending on whether -b>b-a if this is true -b would be the lower limit, otherwise b-a would be.

Essentially what this is isa simplified integral I'm trying to solve which describes two photons overlapping, each with an exponential wavefunction in the time domain. a an b describe offsets in time between the two. Regardless If you plot out those two functions you can see that there should...

...Why is that? Maybe I should have mentioned that each exp() is 0 otherwise.. integration isn't a problem it's the limits of integration that I need to find.

Yes I know they can't be BOTH true, which is why I need to find the condition where they are both satisfied. a and b are real variables I don't understand your 2nd point

An ACTUAL urgent post: Integrating exp() over certain range Hi, Simplified problem: Suppose I have two exponentials \[ e^{ - (x + a - b)} \forall x + a -b> 0 \] \[ e^{ - (x + b)} \forall x + b> 0 \] Then suppose I wanted to integrate: \[ \int\limits_{ - \infty }^\infty {e^{ - (x + b)}...

bump..

Yes, as you reduce the width of the slit you would increase the coherence length upto infinity as the width tends to zero. Like you mentioned your intensity would drop off substantially. By filtering the white light your essentially going from a white light to a monchromatic beam with a fixed...

Hey guys, My name is Raj, I'm actually a student @ toshiba and Anthony Bennett and Andrew Shields are my supervisors. We have a couple of papers soon to be published in APL and PRL ( see http://arxiv.org/abs/0803.3700 and http://arxiv.org/abs/0804.1897) The experiment that anthony performed...
