CERN’s Post

My journey continues at Caltech ! I am joining the Bellan Plasma Group in the department of Applied Physics as a visiting student researcher for the next 6 months. I will be working on the diagnostic and modelling of dusty plasmas. Those plasmas contain small grains of water ice that, when electrically charged, interact with each other, the plasma, and other neutral particles. This gives rises to complex and interesting dynamics.

🔬 Join Us for an Engaging Scientific Talk! 🌟 We are excited to invite you to the upcoming SFB Colloquium featuring Prof. Dr. Tobias Stauber from the Instituto de Ciencia de Materiales de Madrid. 🗓️ Date: Tuesday, 02.07.2024 ⏰ Time: 14:15 🏢 Location: H34 Prof. Stauber will be presenting on the compelling topic of "Nematic versus Triplet Superconductivity in Twisted Bilayer Graphene." Be part of an enlightening session where we explore the phase diagrams of realistic moiré systems, starting from a microscopic tight-binding model for twisted bilayer graphene within the Hartree-Fock approximation. The talk will cover the emergent U(4)-ferromagnet, the symmetry-breaking in real samples, and how this affects the asymmetry between the superconducting phases for electron and hole doping. Additionally, the discussion will extend to the theory of Ising superconductivity in twisted trilayer graphene and how real-space chirality can be measured in linear transport experiments. This is a fantastic opportunity for anyone interested in cutting-edge research in condensed matter physics and materials science. #CondensedMatterPhysics #TwistedBilayerGraphene #NematicSuperconductivity #TripletSuperconductivity #MoiréSystems #MaterialsScience #ScientificResearch #PhysicsTalk #Colloquium #SFB1277 See you there! 🚀

Hello everyone, In the context of my PhD on topological insulators, I had the opportunity to spend a week at the TOCHA school (Topological channels) winter school in Aussois. It was a great opportunity to get concrete explanations on a topic that sometimes seems very theoretical (especially if you are interested in the concept from a mathematical point of view) and to be able to discuss with experienced researchers the possibilities opened by topology in physics. It turns out that a wide variety of topics were presented: topological phases, moiré materials, topological photonics, topological polaritons, topological metamaterials, topological opto-acoustics, non-Hermitian systems... These discussions allowed me to deepen my understanding of the implications of topology in physics. I thank the organizers and the speakers who allowed me to attend the various conferences.

LHC: Advancing Science Together The Large Hadron Collider (LHC) is a remarkable scientific facility located at CERN in Switzerland. What I particularly like about the LHC is its immense scale and the cutting-edge technology used in its design. It is the world's largest and most powerful particle accelerator, enabling scientists to study fundamental particles and their interactions. The LHC has been a contributing factor in today's world in several ways. Firstly, it played a crucial role in the discovery of the Higgs boson in 2012, which confirmed the existence of the Higgs field and gave mass to other particles, deepening our understanding of the universe's building blocks. Secondly, the LHC has expanded our knowledge of the early universe by recreating conditions similar to those just after the Big Bang. This has allowed scientists to study the formation of matter and antimatter, shedding light on the universe's origins. Furthermore, the LHC has fostered international collaboration among scientists, transcending borders and leading to groundbreaking research and discoveries that benefit all of humanity. It has also sparked interest in science and inspired the next generation of scientists and engineers. In summary, the LHC's remarkable achievements in particle physics, its advancements in technology, and its contributions to global scientific collaboration have made it a vital factor in shaping today's world and driving our understanding of the universe's fundamental nature.

EXOSENS was invited to participate to OPTRO-2024 Symposium in January. It was a great opportunity to attend several great speeches among which was the one from Professor Donna Strickland -- University of Waterloo -- recipient of the Nobel Prize in Physics 2018 for developing chirped pulse amplification. I personally gave a keynote speech about 'Revealing the Invisible' and the different strategies for increasing the power of incoming signal without significantly introducing a degradation of the SNR (in low-light or weak signal conditions for instance) : 1/ multiplying electrons in silicon (avalanche effect, impact ionization) 2/ multiplying electrons in vacuum (secondary electron emission) My main message was a reminder that, in order to obtain a good noise-free electron amplifier, the best electron (to be manipulated) remains an electron that is not bound to an atom or molecule and is free to move under the influence of electric and magnetic fields :-)

2025 marks a century of progress in Quantum Mechanics, with pivotal developments dating back to 1925. Max Born coined the term 'Quantum Mechanics,' marking the beginning of a groundbreaking era. German physicists Werner Heisenberg, Max Born, and Pascual Jordan introduced matrix mechanics, while Erwin Schrödinger pioneered wave mechanics and the Schrödinger equation. The United Nations has declared 2025 as the International Year of Quantum Science and Technology, emphasizing global initiatives to raise public awareness about quantum science's significance.

Science is magic explained it is said. Dr. Rolf-Dieter Heuer is a German physicist who served as Director-General of CERN from 2009 to 2015. He played a key role in the Higgs boson discovery through his leadership, overseeing the LHC. Dr. Heuer's strategic decisions and advocacy for the LHC were crucial in achieving this milestone in physics Why do we need to measure Higgs? (Higgs Boson particle)asked an Inventure student. CMS physicists recently measured the mass of the Higgs boson to be 125.35 GeV with a precision of 0.15 GeV, an uncertainty of roughly 0.1%. This new precise measurement of the Higgs boson’s mass will not, at least not on its own, lead us in a new direction of physics. But it does add another piece to the puzzle of the exciting world of subatomic particles, and its connection to the world around us. The Higgs boson mass is an unrestricted parameter in the physics theory describing subatomic particles called the Standard Model, and the value of the Higgs boson mass is connected to understanding the long-term stability of the universe. Its precise knowledge is needed to estimate many of the properties of the Higgs boson and the phenomena that we can observe at future colliders. The Nobel Prize in Physics for the discovery of the Higgs boson at CERN was awarded in 2013 to Peter Higgs and François Englert. We are thrilled at the exposure our students are getting at CERN and feel confident to ask questions of renowned scientists to understand the magic behind science. #STEM #LearningForLife #WeBuildTheFuture #FitForLife #TheInventureAdvantage #NewWorld #NewLearning #CarpeDiem CERN Lavanya Srinivas

Let's be honest, it's hard not to be awestruck by a massive, precision-engineered, particle accelerator that is unlocking the secrets of matter by smashing protons together at relativistic speeds! This week I had the opportunity to visit one of the wonders of the modern world at CERN with a delegation from Ireland. As Ireland's submission for associate membership to CERN is in progress, we came to Geneva to gain a deeper understanding of how Ireland might best benefit from, and contribute to, this remarkable facility. The scale, ingenuity and precision of the engineering and physics at CERN are mind-blowing. As the collider is currently offline, it afforded us the rare privilege of visiting the detector 100M below ground. The LHC (Large Hadron Collider) has a circumference of approx. 27Km and thousands of powerful, supercooled magnets that contain two accelerating beams of protons (going in opposite directions) at very nearly the speed of light. Once they are up to full speed the beams are nudged, ever so slightly, until they collide at the exact location of a sophisticated suite of sensors. The sensors gather incredible amounts of data in fractions of a second that allow physicists to unpack the exact composition of the subatomic particles created by the collision. The visionary and long-term thinking at CERN is truly inspiring. Not content with the current speed of 99.9999991% the speed of light, the team at CERN are already shaping a future vision with a new accelerator ring of up to 100Km in circumference that will deliver vastly more energy and should help unlock even more new physics and increase our understanding of the universe. Many thanks to our hosts at CERN who gave so generously of their time to host an Irish delegation of university leadership, researchers, government representatives and ambassadors. A special thanks to my researcher travelling companions for helping me to brush up on my very rusty particle physics. #CERN #science #technology #Physics #irishresearch.
