The second paper from my PhD has just been published on Physics of the Earth and Planetary Interiors! 🎉 Have a look at the full text here: https://lnkd.in/eAMy_7rW. This paper demonstrates how important it is for tomography models to be accompanied by uncertainty and resolution information, especially when interpreting together different physical properties. We have built our models using the SOLA method (based on a Backus-Gilbert approach) applied to normal modes, showing the huge potential of both this innovative inversion method and type of data. Many thanks to my co-authors Christophe Zaroli and Paula Koelemeijer

🚀#mdpisymmetry #featurepaper Excited to share a Feature Paper with you. "More Insights into Symmetries in Multisymplectic Field Theories" 🔸https://lnkd.in/gx9Uh5G8 🔹Authors: Arnoldo Guerra IV and Narciso Román-Roy Universitat de Barcelona Universitat Politècnica de Catalunya 🔸Abstract: This work provides a general overview for the treatment of symmetries in classical field theories and (pre)multisymplectic geometry. The geometric characteristics of the relation between how symmetries are interpreted in theoretical physics and in the geometric formulation of these theories are clarified. Finally, a general discussion is given on the structure of symmetries in the presence of constraints appearing in singular field theories... #fieldtheory Physics Section of Symmetry

Proceedings of the Twentieth International Conference on Quantum Physics and Logic Shane Mansfield, Benoît Valiron, Vladimir Zamdzhiev This volume contains the proceedings of the 20th International Conference on Quantum Physics and Logic (QPL 2023). The aim of the QPL conference series is to bring together academic and industry researchers working on mathematical foundations of quantum computation, quantum physics, and related areas. The main focus is on the use of algebraic and categorical structures, formal languages, type systems, semantic methods, as well as other mathematical and computer scientific techniques applicable to the study of physical systems, physical processes, and their composition. https://lnkd.in/dmXnRewT

An amazing read that took me too long to read titled "The Mechanism Behind Probability" by Sydney Ernest Grimm. This paper delves into the origins and applications of probability theory in the context of quantum mechanics, providing a unique perspective on how nature itself operates under the principles of probability. Key Insights and Takeaways: Fundamental Role of Probability: The paper discusses how changes within observable reality, especially at the quantum level, adhere to probability theory, highlighting its foundational role in the structure of the universe. Historical Context: Starting with macroscopic examples like dice throwing, the paper illustrates how probability has always been a part of scientific inquiry and how it scales down to the quantum level. Quantum Mechanics: In physics, probability theory predicts the outcomes of experiments involving quantum interactions, where causality is assigned to probabilistic models rather than deterministic ones. Non-Local Universe: One of the intriguing aspects discussed is the non-local nature of the universe, where local changes influence other local changes instantaneously, suggesting a universe of interconnected probabilities. Practical Implications: The insights from this paper enhance our understanding of probability in quantum mechanics, which is crucial for advancements in fields like quantum computing and theoretical physics. Understanding these fundamental principles helps us appreciate the complex interplay of forces at the smallest scales of reality, providing a deeper insight into the nature of the universe.

Changes from the First Edition include many new discussions of modern quantum systems (such as Bose-Einstein condensates, the quantum Hall effect, and wave packet revivals) all in the context of familiar textbook level examples. The book continues to emphasize the many connections to classical mechanics and wave physics to help students use their existing intuition to better learn new quantum concepts. https://lnkd.in/gxKxkH6D

Our latest manuscript is out! This is a story of three friends (brothers in physics, Andre Stoffel, PhD Santiago Francisco Caballero Benitez) who did a masters together, followed different paths for their PhDs, and found a way to put together what they learned. We aim to provide a practical tutorial on using group theory for the analysis of photonic lattices for those less familiar with abstract algebra methods. Going beyond the standard optical-quantum analogy, we show that coupled-mode equations for intensity and phase allows us to calculate envelopes for inputs within an intensity class, as well as individual input field amplitudes, eliminating the need for point-to-point propagation calculations. https://lnkd.in/eSuuHfJK

🔍 Save the Date! Colloquium on Quantum Geometry at Konstanz University 🎓 I am excited to announce my forthcoming colloquium "From Quantum Geometry to Kähler Bands: Moiré Materials and Beyond," to be held on the 11th of January at Konstanz University. 📅 Date: January 11, 2024 📍 Location: Konstanz University, SFB 1432 Colloquium 🎙 Speaker: Bruno Mera 👥 Host: Oded Zilberberg 🙌 Special Thanks: This visit is made possible by the support of my dear colleague and friend Greta Villa. 📚 Abstract: This colloquium aims to provide a pedagogical introduction to the topic of quantum geometry, i.e., the geometry of families of quantum states. Beginning with a foundational introduction to quantum geometry, we delve into the specific case of Bloch bands, unraveling the inequalities that emerge relating the quantum metric and the Berry curvature, the saturation of which implies holomorphicity and gives rise to the concept of Kähler band. The discussion finds direct applications to twisted bilayer graphene in the chiral limit, where the saturation of these inequalities plays a pivotal role in stabilizing fractional Chern insulating phases. Highlighting the significance of these insights, we draw connections to the existence of an algebra of projected density operators. Intriguingly, this algebra mirrors the Girvin-MacDonald-Platzman (GMP) algebra found in the Fractional Quantum Hall Effect (FQHE). Join us to uncover the quantum geometry of materials like twisted bilayer graphene and explore broader implications for understanding and predicting novel quantum phases. Looking forward to an engaging discussion and your presence at this exciting event! #QuantumGeometry #Colloquium #Physics #KonstanzUniversity #ScienceTalk

Dear, Why is AdS/CFT the hottest topic in theoretical physics? In the ever-expanding cosmos of theoretical physics, there exists a concept that electrifies the minds of scientists and philosophers alike: the AdS/CFT correspondence. At its heart lies the brilliant revelation of Juan Maldacena, a physicist whose groundbreaking paper, "The Large N Limit of Superconformal Field Theories and Supergravity," catapulted him into the annals of scientific history. This paper, with its thousands of citations, stands as a titan among academic works, weaving the fabric of reality by uniting two seemingly disparate realms: Anti-de Sitter space (AdS) and conformal field theory (CFT). The AdS/CFT correspondence, a manifestation of the holographic principle, teases at a deeper cosmic truth—a theory of everything. It beckons us to journey into the unknown, where gravity and quantum fields intertwine, where spacetime is but a holographic projection, and where the uncharted territory of a unified understanding of the universe awaits its intrepid explorers.
