I used to be on this platform, but not since ~late 2024. Keeping the handle though. Theoretical Physicist working on all things quantum. Enjoyer of penguins.

Stability of emergent time periodicity in a few-body interacting system

https://t.co/CRyBPBoBbA

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

[Steve Campbell @quantumwizard]

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)

kudos to Brody for both an interesting work and for using Yes, Prime Minister as the subject

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

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

[Steve Campbell @quantumwizard]

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 https://t.co/HTioJxgEVm

My work with Sebastian Deffner (@quthermo_comp) and Diogo O Soares-Pinto, "Conditional quantum thermometry—enhancing precision by measuring less" has just been published on Quantum Science and Technology: https://t.co/6BGDVfLQC1 via @QuantSciTech
Happy reading!

[Steve Campbell @quantumwizard]

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!)

[Steve Campbell @quantumwizard]

@HyperboIeva @taliesinb @MattWillani @symbolica @PhasecraftLtd i'm glad it you also had fun that day. I dunno about you, but the near 3 hours (if memory serves correctly!) seemed to pass in a flash!

[Steve Campbell @quantumwizard]

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.

(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.

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

[Steve Campbell @quantumwizard]

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!

[Kevin Mercurio @kjbmercurio]

Full house! Big thanks to organizers and speakers, plus @IBMResearch for sponsoring #PintOfQuantum and for helping to support @pintofscienceIE in bringing #SciComm to Ireland’s best pubs 🤩🇮🇪🍻
