کارگاه فیزیک انرژی‌های بالا
پژوهشکده فیزیک، پژوهشگاه دانش‌های بنیادی

۲۲ تا ۲۳ آذر ۱۴۰۳(۱۲-۱۳ دسامبر ۲۰۲۴)

(پنجشنبه و جمعه)


پژوهشکده فیزیک در نظر دارد کارگاهی دو روزه به صورت حضوری و با هدف کسب برخی از مهارت‌های ضروری در دو حوزه تحقیقاتی فیزیک نوسان نوترینوها و ساختار هادرون‌ها برگزار نماید. از علاقه‌مندان و پژوهشگران حوزه پدیده‌شناسی دعوت می‌شود در این کارگاه ثبت‌نام نمایند.

این دوره دارای دو بخش است. بخش اول به آموزش مفاهیم ضروری در مدل‌سازی نتایج آزمایشگاهی می‌پردازد. تمرکز این بخش از کارگاه بر روی آزمایش‌هایی است که ساختار هادرون‌ها را بررسی می‌کنند. در بخش دوم بسته نرم‌افزاری GLoBES معرفی شده و در کنار آموزش مفاهیم اساسی نوسان نوترینوها، شما با برخی از کاربردهای این نرم‌افزار آشنا خواهید شد.

ثبت نام در این کارگاه برای عموم پژوهشگران آزاد است. در صورتی که محقق شاخه ذرات هستید و مطالعات شما در حوزه تحقیقاتی مرتبط با ساختار هادرون‌ها و یا فیزیک نوترینوها است، ثبت‌نام در این کارگاه برای شما توصیه می‌شود.

اولویت ثبت‌نام برای دانشجویان کارشناسی ارشد و دکتری خواهد بود. پژوهشگران پسادکتری می‌توانند در این دوره شرکت نمایند. دانشجویان کارشناسی در صورت وجود ظرفیت، به صورت مشروط پذیرفته خواهند شد.

In this talk, we present binomial complexities in sequences of symbols, a branch of combinatorics on words. We explore variations of factor complexity, specifically focusing on k-binomial complexity. Binomial complexities, initially introduced by Rigo and Salimov in 2015, provide insight into the structural properties of sequences by considering equivalence relations based on subword occurrences. The talk covers key findings on bounded binomial complexities observed in Sturmian words, Thue-Morse words, and fixed points of Parikh-collinear morphisms. We also address open questions concerning the relationship between factor complexity and binomial complexity, examining the conditions that contribute to their stability or divergence. The presented research revolves around two main questions: Can factor complexity coincide with binomial complexity under certain conditions, and do there exist words for which these complexities become equivalent at larger k-values? We investigate bounded and unbounded complexities and attempt to describe words that exhibit specific behaviors based on their complexity, using examples like Thue-Morse and Fibonacci words. Ultimately, we aim to uncover how different types of complexity can reveal hidden patterns and structures within infinite words, offering fresh perspectives on the vast field of symbolic sequences.

A Tevelev degree is a type of Gromov-Witten invariant where the domain curve is fixed in the moduli. After reviewing the basic definitions and previously known results, I will report on joint work with Lehmann, Lian, Riedl, Starr, and Tanimoto, where we improve the Lian-Pandharipande bound on asymptotic enumerativity of Tevelev degrees of hypersurfaces and provide counterexamples to asymptotic enumerativity for certain other Fano varieties.

A map $g:{0,1}^n o {0,1}^m$ ($m > n$) is a hard proof complexity generator for a proof system P if and only if for every string $b in {0,1}^msetminus Range(g)$, the formula $ au_b(g)$ naturally expressing $b otin Range(g)$ requires superpolynomial size P-proofs. One of the well-studied maps in the theory of proof complexity generators is the Nisan-Wigderson generator. Razborov [Annals of Mathematics 2015] conjectured that if $A$ is a suitable matrix and $f$ is an NP $cap$ Co-NP function hard-on-average for P/poly, then NW$_{{f,A}}$ is a hard proof complexity generator for Extended Frege. In this talk, we prove a form of Razborov's conjecture for AC$^circ$-Frege. We show that for any symmetric NP $cap$ Co-NP function $f$ that is exponentially hard for depth two AC$^circ$ circuits, NW$_{{f,A}}$ is a hard proof complexity generator for AC$^circ$-Frege in a natural setting.

Abstract:

This workshop will delve into cutting-edge developments in particle physics aimed at advancing our understanding beyond the Standard Model (SM). While the SM has provided a robust framework for describing elementary particles and their interactions, evidenced by its success up to TeV-scale energies at the LHC and the 2012 discovery of the Higgs boson by the ATLAS and CMS collaborations, it leaves several profound questions unanswered. The workshop will explore recent theoretical advancements and experimental results from the LHC with a focus on Higgs boson, top quark, and bottom quark physics, alongside pivotal topics in Beyond the Standard Model (BSM) physics, such as dark matter and baryogenesis. By bringing together experts in these fields, the workshop aims to foster discussions on potential extensions of the SM above the electroweak scale, addressing key challenges in particle physics and the search for new phenomena that could illuminate the mysteries of dark matter and the origin of matter-antimatter asymmetry.

Winter school on Physics of Complex Fluids (PCF)
School of Physics, IPM
February 19-20, 2025 (Esfand 1-2, 1403)


The Winter School on Complex Fluids aims to enhance the knowledge of postdoctoral researchers and graduate students, particularly at the doctoral level, in the physics of fluids and complex systems. This program provides an in-depth exploration of the physics of complex fluids and hydrodynamic phenomena in soft and dispersed materials, delivering a solid foundation in these fields. The school covers a diverse range of materials with physical and mechanical properties between those of liquids and solids, including macromolecules (e.g., polymers in solution or melt, liquid crystals), suspensions, dispersions (colloids, emulsions, foams, immersed granular materials), dry granular materials, biological fluids, and self-assembling fluids like surfactants. These systems have applications in numerous scientific and industrial fields.

The curriculum combines experimental techniques with theoretical research to uncover fundamental mechanisms governing the dynamics of complex fluids. Participants will also gain practical experience with measurement techniques for dynamic and static parameters and explore simulation methods for modeling natural and industrial systems. Additionally, the school emphasizes applied fluids, addressing critical challenges in energy transition and biological sciences.


The deadline for registration is 3th of February, 2025 (15 Bahman, 1403).
