Stability of emergent time periodicity in a few-body interacting system iopscience.iop.org/article/1… We examine the onset and resilience of emergent #timeperiodicity in a few-body all-to-all interacting Lipkin–Meshkov–Glick #manybody model, where one of the constituents is locally in contact with a thermal bath. Employing both a #collisionmodelframework and a suitable #timecontinuousdescription, we show that stable time-periodic behavior can only be exhibited when the bath acts as a purely #dissipative channel. We assess the role that the microscopic interactions within the system play, establishing that for the all-to-all model the introduction of temperature leads to a melting of the emergent time periodicity, in contrast to stable long-time behavior which can be maintained for nearest neighbor XXZ type interactions. I am happy to see this out in the @NJPhysics.

for the bank holiday, i shall redirect my efforts more suitably to remembering joys of my childhood. Screw pumpkins...carved turnips are proper nightmare material

great to see this out into the world -- and thanks to the @AvHStiftung funding which made it possible. I learned a lot doing this...particularly the subtleties about what systems we might (or might not!) consider a bona-fide time crystal.

i just hope that with the formation of the new @Researchirel this will come with a renewed look at underfunding of research in Ireland (at 0.2% GDP the country will struggle to be internationally competitive) linkedin.com/pulse/talent-dr…

this was my wife trolling me with todays @xkcdComic xkcd.com/2986/ ....she's not wrong.

kudos to Brody for both an interesting work and for using Yes, Prime Minister as the subject arxiv.org/abs/2409.08930 the scene it refers to is one of the many excellent moments youtube.com/watch?v=6GSKwf4A…

and stint 2 of my @AvHStiftung fellowship w/@jenseisert and @QuControlBerlin wraps up. Scientifically it was amazing. And dare I say that personally, I may have had even more fun this year enjoying the other things Berlin and nearby places had to offer (....like WACKEN!!)

my last weekend in Germany before I head back to Dublin and I managed to squeeze in another tattoo convention -- this time with added metal. And indeed I leave with a fresh #kneeditch tattoo

I am down with this! #Noether doi.org/10.1119/5.0229624

just got to Oxford and i am bringing some class to the Keble college...also had a chance to see Einstein's blackboard. Oxford is a bit like Disneyland for academics

we laugh because it is probably a little bit on the nose 🤣

Having just seen Amon Amarth at Wacken, I understand that this is Thor smashing his anvil above Berlin. I shall have a good evening watching out my window and listening to Twilight of the Thunder God, I'm just missing the drinking horn.

A wonderful paper that also kicks off a new Focus on Thermodynamics of Quantum Coherent Platforms collection for @QuantSciTech we are pulling together. Submissions are open tinyurl.com/2n2zrcj4

i am sad that I'm missing #QTD2024 this year, but I had a good reason. the last few months i've been back in Berlin on stint #2 of my @AvHStiftung fellowship w/@jenseisert & I've taken full advantage to experience all aspects of German culture!(& doing some fun science obvs!)

while I doubt we'll abandon writing grant proposals anytime soon, I don't think the results of this study will come as a massive shocker to many. link.springer.com/article/10…

(1/n) Introducing 🥁... the autonomous quantum processing unit! Our proposal for a thermodynamically self consistent model of quantum computation which we hope will serve as a framework to examine the physics of computation and complexity. scirate.com/arxiv/2402.00111

Now that term is finished, I take myself to the cinema to see xmas classic Die Hard and what is the first thing I see!?! @antmarcarr pushing his astrophysics agenda for @ucddublin @UCD_physics

I had a cracking time last night getting out of @ucddublin and heading to the pub for #PintOfQuantum to have a go at explaining the u̶n̶c̶e̶r̶t̶a̶i̶n̶t̶y̶ (indeterminacy!!) principles while not so elegantly sidestepping questions about interpretations of quantum mechanics!

in terms of spam journal emails this one has the greatest wording. I wish all my articles had a "victorious release"....
