[Master Thesis] [Atom Interferometer Observatory and Network] [Gravitational Waves] [Imperial College London] This summer, I am working on the AION project (Atom Interferometer Observatory and Network) which is part of the High Energy Physics department in Imperial College. AION aims to explore the nature of dark matter and provide a pathway towards detecting gravitational waves from the very early Universe and astrophysical sources in the mid-frequency band ranging from several mHz to a few Hz.  My master thesis is about sideband modulation of spectroscopy light with a waveguide EOM to characterise velocity profiles of atomic strontium beams which are used as the atoms sources for the experiments. Accurately characterising the velocity profiles of the sources will improve the quality of the Zeeman slowing and of the overall MOT processes.

The world we experience seems very predictable, but on the atomic and subatomic level, things get strange! Unlike everyday objects, light and matter can behave both like waves and particles. Imagine a tennis ball acting like a blurry wave at times! Additionally, energy comes in "packets" called quanta, not smoothly like filling a glass with water.

🔬✨ CERN’s Rare Kaon Decay Discovery Hints at New Physics ✨🔬 Scientists at CERN have observed an ultra-rare kaon decay that could challenge the Standard Model of particle physics. Known as a "golden channel," this decay occurs in fewer than one in ten billion kaons. Interestingly, the decay rate observed was about 50% higher than predicted, which could signal new physics. The experiment, called NA62, achieved a five-sigma significance, confirming that the findings are statistically sound. While this doesn’t dismantle the Standard Model, it suggests possible new phenomena, highlighting how much we still have to discover at the subatomic level. #Physics #CERN #KaonDecay #StandardModel #ParticlePhysics #ScientificDiscovery #NewPhysics #ScienceNews

I'm thrilled to share my latest research: "Exploring Supersymmetry, Gravitational Waves, and Extra Dimensions through CMB Simulations: A Detailed Study". In this comprehensive study, we delve deep into the realms of #supersymmetry, #gravitationalwaves, and the intriguing possibility of #extradimensions, using cutting-edge simulations of the Cosmic Microwave Background (CMB). Key Highlights: - Detailed analysis of supersymmetric particles' potential impact on the CMB. - Exploration of gravitational wave signatures within various cosmological models. - Insights into how additional spatial dimensions could influence the fabric of the universe. This work aims to push the boundaries of our current understanding of the cosmos, contributing to the ongoing search for a unified theory of everything. The findings are not only a step forward in theoretical physics but also open new avenues for experimental validation. I would love to connect with fellow researchers, physicists, and enthusiasts to discuss these findings and explore future collaborations. Your feedback and insights are highly appreciated! #Physics #Cosmology #CMB #QuantumMechanics #Astrophysics #Research #Science #BlackHoles #StringTheory #AcademicResearch

New Research: Exploring Extra Dimensions Through High-Energy Collisions and Gravitational Wave Analysis I'm excited to share our latest work, where we delve into one of the most pressing challenges in modern physics: the potential existence of extra dimensions beyond the familiar four-dimensional spacetime. Our study investigates how these additional dimensions could influence high-energy particle collisions at the TeV scale and affect the propagation of gravitational waves. Using advanced simulation models, we've explored scenarios that could lead to the detection of gravitons, deviations from the Standard Model, and the interaction between dark matter and extra dimensions. Key Insights: - Extra dimensions could become observable in future LHC experiments that exceed energies of 14 TeV, providing new data on particle collisions. - Gravitational waves could offer critical insights, potentially revealing the presence of extra dimensions through the propagation of gravitons into higher-dimensional space. - The interaction between dark matter and ordinary matter may be significantly affected by extra dimensions, suggesting new pathways for direct detection experiments. This research builds on recent developments at CERN, LIGO, Virgo, and other observatories, helping to bridge the gap between quantum mechanics and general relativity. #Physics #Research #ExtraDimensions #ParticlePhysics #GravitationalWaves #DarkMatter #HighEnergyPhysics #LHC #QuantumMechanics #GeneralRelativity #ScientificDiscovery #DataScience #AdvancedSimulations #InnovationInScience
