Quantum chaos Definition and 14 Threads

Currently it's a very hot topic, so it would be nice to have a thread on this. Those who never heard of it may start from https://en.wikipedia.org/wiki/Sachdev–Ye–Kitaev_model A good review is https://arxiv.org/abs/1711.08482

I might have a few questions about this topic in the future. So I am just asking if there are any experts on this topic here? Thanks in advance! BTW I asked also in physics stackexchange why they don't have a tag of QC, but you know how that site is...

The system in which I tried to calculate the Hamiltonian matrix was a particle in a stadium (Billiard stadium). And I used the principle where we take a rectangle around the stadium in which the parts outside the stadium have a very high potential V0. We know the wave function of a rectangular...

Hi, I was curious to know what the perception of quantum chaos is. It seems a bit on the fringe, but at the same time it seems interesting. An adviser I'm considering working for works on both solid state physics applications and does some theoretical work in quantum chaos, so I'm wondering if...

What are the topics which are been perceived by researchers around the World on the topic of Quantum Chaos? I know my questions is not specific, but I do not have any idea to ask about anything specific.

Is there a good explanation for how we can explain an ordered universe arising from an inherently uncertain quantum world? I'm aware of the conflict between special relativity and quantum vacuum fluctuations, but is this the only issue? The correspondence principle would seem to imply that...

Hello all, For an undergraduate essay, I am studying the development of quantum chaos in a 1D spin 1/2 chain (my main source paper can be found here:http://scitation.aip.org/content/aapt/journal/ajp/80/3/10.1119/1.3671068). One of the main tools used to distinguish chaotic from non chaotic...

Hello everyone, I would like to know if Bohm Mechanics (and weak measurement) could be useful in understanding Quantum Chaos theories? I'm currently in search of a PhD in Foundation of QM and I would like to know if doing a project that combine the trajectories coming from Bohm Mechanics with...

http://www.technologyreview.com/blog/arxiv/27628/?p1=blogs For those who might not know of the theory the goal of quantum chaos theory is to explain all of classical physics including classical chaos as emerging from quantum systems. They've had some experimental success in the past, but this...

what is quantum chaos? dose it exist realy? the original definition of classical chaos is a system with exponential sensitivity to initial conditions. however in quantum mechanics because of the linear property of the schrodinger equation, variation on initial condition of the wave function...

Are there any attempts to synthesize between these two theories? I mean are there methods from QFT being used in QC and vice versa? I asked one professor from my univ if I were to research under his belt in QC, would I need some QFT knowledge and he said not. So I wonder are they really...

Apologies if this is the wrong forum, but I have a pair of thematically connected questions that I can't really fit anywhere else. Please move if this is better suited to the quantum physics forums. My first question being: The Poincare-Bendixon theorem states that chaos can only occur for...

According to Prof. Sir M. Berry's argument, the Quantum Mechanics transition to Classical Mechanics (when the Planck constant approaches 0) is a singular process. So there is a lot of new physics here. Let's consider the Schrodinger Equation. If the wave function at t=0 has a small error...

can someone please explain me in a layman (or even in elaborative manner) way, what is quantum chaos?
