Our new preprint is finally on @arxiv! How to control the dynamics of magnetic moments by currents in a magnetic junctions? We investigated this question using a combination of quantum and classical equations of motion. Check it out!

nature has actually contacted me for comment about accusations that Sci-Hub is a threat, here is my full response / it is clear that academic publishers care about their money, not about security of other people

John Wheeler's game of negative 20 questions (you keep changing the answer, to be consistent with all prior answers, as an allegory of quantum theory).

@careerconversa1 What do you mean by „value“? Monetarily or reputation-wise? And which society? Industry and job-related, or the „general public“/„plebs“/„rich bigwigs“? As always, it depends. In some of the spheres PhD are valued, in some not at all.

@rebeccatraldi @juliababuta @AcademicChatter Bookmarking? Pff, how oldschool. Using the „group tabs“ feature of google chrome gives on top of that the illusion of organisation in all this mess. And it feels as if you really accomplished something. At least.

I'm excited to be co-organizing (together with Liang Jiang, Vedika Khemani, and Sagar Vijay) a KITP workshop on many-body physics and quantum computing from 8/15/22 - 10/7/22.

Soft application deadline is Sep 26.

Two #classical #spins interact with #quantum electrons, acting as sources for spin-waves. Although spatially separated, the two local spins 'feel' an indirect interaction, mediated by the electrons.

This plot from https://t.co/r7QWouKWZ1, the energy density in a spin chain as a function of position (horizontal) and time (vertical) shows the collapse of a false vacuum bubble resulting in production of mesons which propagate ballistically at relativistic velocity.

A #quantum particle trapped by two attractive delta potentials. Probability density and Wigner's function.

[Rudolf Smorka @RSmorka]

@vijay_mocherla @zlatko_minev @quant_phys Your questions go in the right direction. Let me say that both points are intrinsically connected: Dephasing is local, meaning that the short-time behavior of small isolated systems is identical with that of systems in the thermod. limit (e.g. open quantum systems)

[Rudolf Smorka @RSmorka]

Response of #quantum electrons to a #classical spin in 1D. Due to interaction with the spin, electrons form spin-waves, which propagate through the lattice, and then reflect at the boundaries. @quant_phys

[Rudolf Smorka @RSmorka]

@vijay_mocherla @zlatko_minev @quant_phys Exactly. The classical spin has fixed magnitude S=1 (red arrow). The blue arrow shows the local spin expectation value, which has fluctuating magnitude (but always <=1/2). To put the focus on the dynamics, I enlarged the blue arrow a little bit.
