Our paper Controlling heat and particle currents in nanodevices by quantum observation (from our previous post) keeps getting attention online. Another note about it was written by Phys.org. And a Russian website has written about it (and change the colors of some of its images.

Our paper Controlling heat and particle currents in nanodevices by quantum observation has been published in Nature Partner Journal Quantum Materials. The paper has received considerable social media attention, according to the Altmetric. The press release also has been picked up by some outlets.

 

I’ve been traveling a lot for work, and I’m finally catching up. Last May I was in Melbourne, visiting my old friend and collaborator Kavan Modi at Monash University. We worked more on Operational Characterization of Non-Markovian Processes, a project we have been working on for some time now. As an aside, discussing random ideas,  we got some interested results on an operational definition of detailed balance. Once they are more mature, I’ll post more here. Him and his group kept me very busy, I gave 3 different talks to different audiences.

I really enjoyed Melbourne, it reminded me of San Francisco, but friendlier and more laid back. Coffee was incredible! Food also was very good, I particularly loved the big Melbourne breakfasts,  like avocado toast.

We went to the fantastic Victoria Market to purchase some exotic meats.

I really enjoy the Wallaby. Kangaroo was good in both cuts, much better quality than other cheap Kangaroo cuts I’ve had before.

Melbourne is very vibrant and full of parks. One night we some possums at the park.

We also saw a fox, but we couldn’t capture it on camera. Later that night we saw a very interesting person in the tram.

I honestly don’t know if this was someone in need of help, or if it was some clever modern theatrical performance.

This year it will be the 90th anniversary of the legendary Solvay Conference where all the big names in Quantum Mechanics congregated. Here is a nice video documenting it.

Weirdest paper I’ve seen on quant-ph in a long time:

胡锦涛开通“网络民意直通车”-东北网国内-东北网:2021-6-28 · 早在2021年，胡锦涛、温家宝就公开了网民身份，向外界展现对互联网的重视；2021至2021年，温家宝连续四年在“两会”中外记者招待会上主动问候中国网民，并感谢网民分忧，公开肯定了这种“民意直达高层直通车”的沟通方式；去年初，中共中央政治局集体学习

My review: the paper is not funny.

I’ve been reading a fantastic paper by an international collaboration on Quantized thermal transport in single-atom junctions. One of the authors has kindly put a video overview of the experimental set up online that is interesting and accesible. Check it out.

Our paper has been published in Europhysics Letter!

Dephasing-controlled particle transport devices

We study the role of dephasing in transport through different structures. We show that interference effects invalidate Kirchhoff’s circuit laws in quantum devices and illustrate the emergence of Ohmic conduction under strong dephasing. We present circuits where the particle transport and the direction of rectification can be controlled through the dephasing strength. This suggests the possibility of constructing molecular devices with new functionalities which use dephasing as a control parameter.
