Afternoon session of the "Topology in Lattice Systems 2026" workshop at @UTokyo_News starts with Jun Nishimura (@kek_jp) who presents his work on the #signproblem & topological freezing deploying the #complexLangevin method & Lefshetz thimbles.
Great to be back in Bern๐จ๐ญat the Albert Einstein Center for the 2025 "Workshop on the #SignProblem in QCD and beyond".

Latest news on from-line research on one of the toughest problems in modern theoretical physics spanning condensed matter to nuclear.
You can run, you can hide but the #signproblem will still haunt you in Euclidean #latticeQCD. One interesting manifestation in Michael Wagman's (@Fermilab) talk: signal/noise problem in nucleon correlation functions interpreted as sign problem. Contour deformations to tackle it.
2nd day of @EctTrento #ML & #lattice #fieldtheory workshop kicks off with a talk by Yukari Yamauchi @UW (Institute for Nuclear Theory) on a complex generalization of #normalizingflows. Converting a #signproblem laden complex distribution into a real Gaussian. #womeninphysics
Next up Neil Warrington @UW (Institute for Nuclear Theory) tells us about path integrals for #Qubits (continuous spheres!) and the use of contour deformations to tackle the associated #signproblem. Interesting to see how path integrals for finite number of d.o.f. behaves.
First up Gurtej Kanwar @unibern @MIT on using #machinelearning to attack the signal to noise challenge in #latticeQCD. Actually a manifestation of the ubiquitous #signproblem and thus amenable to integration contour deformations here constructed systematically via ML.
Pleasure to present our research on #machinelearning assisted #ComplexLangevin simulations of #quantum real-time dynamics at the @uisimf @unistavanger #NordicLattice meeting. With #ML: incorporate system specific prior info in sims. to beat NP-hard #signproblem. @forskningsradet
Our @uisimf @unistavanger postdoc R. Larsen presents his recent idea to tame the #signproblem w/ line integrals at 2023 #NordicLattice meeting. Separating integration over oscillatory integrals from sampling & treating it with high precision integrator is key. @forskningsradet
Excited to see so many colleagues attend the 2023 @UniStavanger - @UniHeidelberg #lattice seminar series today. Started with flash talks from group members: news on taming the #signproblem for fermions & real-time sims using complex Langevin & novel strategies. @forskningsradet
#Mathematics is really great as it can tell us that beating the game #Tetris has the same computational complexity ( need for computing resources ) as simulating how #quantum fields evolve in time. Both problems are NP-hard. #signproblem

Our PhD student Daniel Alvestad is in Israel this week for #SIGN22, the 8th Intl. Workshop on the #SignProblem @TelAvivUni. In his talk he presented his latest research on novel simulation strategies for quantum systems which defy standard simulation strategies. @forskningsradet
A real pleasure to give an in-person seminar @uctphysics @UCT_news on recent progress of my group @UiSIMF "towards robust real-time dynamics with complex langevin". Novel strategies to incorporate system specific knowledge in simulations to beat the #signproblem. @forskningsradet
Can I get some๐love for methodsโค๏ธโ๐ฅdevelopment ๐ซถ ? Feedback on my denied @forskningsradet proposal: those methods you propose are neat but you did not promise us the sky on how you are going to revolutionize physics with them. Apparently we have the methods we need๐#signproblem
Research on #latticeQCD and the #signproblem connects scientists from all around the globe ๐ฉ๐ช๐ง๐ท๐ฉ๐ฐ๐ณ๐ด๐ฆ๐น๐ฎ๐ณ. Tasting some of the regional Rhine River region dishes with colleagues at #Lattice2022 in #Bonn.
We share with our friends @Bennijaeger1 @felixpgziegler & Felipe Attanasio from @NATsdu @SyddanskUni a passion for fighting the #signproblem with complex Langevin. Great to see their progress on QCD at finite density at #Lattice2021, our focus otoh is real-time. @forskningsradet
Happy to see our analysis of the easing the Monte Carlo #signproblem - developing both a systematic, generally applicable, and practically feasible methodology for easing the sign problem and a complexity-theoretic analysis going to press in the @ScienceAdvances.
What is the computational complexity of easing the #signproblem of #quantum Monte Carlo? The answer is here (it took us three years to come up with this).

Think positive ako ng think positive yan tuloy nakalimutan ko yung negative. Huhuhu.

Do you "c" the problem? #signproblem
