Condensed Matter Theory
The group performs research on diverse topics that span forefront areas of hard/soft condensed matter physics and emerging areas at the intersection of physics and other disciplines. Specific research areas include the electronic structure and spectroscopy of high-temperature superconductors and other complex materials, nanotribology
atomic-scale friction in crystalline and polymeric materials, theoretical/computational materials science, cardiac non-linear dynamics, and theoretical/computational neuroscience.

High Energy Theory
The faculty and students in the theoretical particle physics group are actively exploring questions concerning supersymmetry SUSY, and more specifically its local extension to supergravity SUGRA, with a view to understanding the connection between the universe at very large and very small scales. This leads to the study of supersymmetry and supergravity, possible extra dimensions beyond the usual four, and related exotic phenomena, such as mini-black holes, which may be produced at accelerators or by ultra-high-energy cosmic rays.
Our formal investigations in superstring theory and M-theory
are also conducted with the purpose of making connections between fundamental theory and experiment. The elementary
particle theory group at NU initiated the PASCOS and SUSY series of conferences, which have become major conferences in high-energy physics.

Complex network research is not a single discipline; it is highly interdisciplinary, seeking the answers to some fundamental questions about living, adaptable, and changeable systems. Several of the main disciplines are “network theory” involving the research areas of computer science, network science, and graph theory. Another is “network science (NS)” attempting to research engineered networks, information networks, biological networks, semantic networks, and social networks, whereas “dynamic network analysis (DNA)” will use traditional social network analysis, link analysis and multi-agent systems involving large amounts of electronic data. We should also add “complex adaptive systems,” which is grounded in modern chemistry, biological views on adaption, expatriation, and evolution. In all of these and more network-related areas, the study of emergence and self-organization are fundamental. Although academic disciplines are hugely diverse in complex network research, here in the Department of Physics, disciplines in statistical analysis involving physics, mathematics, and computational analysis (data mining) are its primary focus.

The faculty is actively pursuing research at the frontiers of nanoscience. The thrust areas in
nanophysics include the following: left-handed metamaterials for photonic
crystals, nanomedicine, spintronics, mesoscopic physics, low-dimensional electronic systems, nanomagnetism, and
quantum chaos. Research is aimed at the synthesis of nanoscale materials and devices, as well as fundamental materials issues.

Experimental Particle Physics
The Experimental Particle Physics group concentrates its efforts on the following activities: CMS and the Pierre Auger Observatory. Compact Muon Solenoid at LHC (Alverson, Barberis, Orimoto, Wood): The CMS detector recently resumed operations at the Large Hadron Collider (LHC), located near Geneva, Switzerland. The LHC is currently colliding protons at 13 TeV, the highest energy available in the world. At Northeastern, we are supporting the end cap muon detector and the electromagnetic calorimeter, are studying the newly-found Higgs boson, and are searching for leptoquarks (exotic particles with properties of both leptons and quarks), Dark Matter, massive new gauge bosons (Stueckelberg Z-primes), and other new physics. Post-doctoral fellows include Dr. Andreas Massironi, Dr. David Morse, and Dr. Daniele Trocino. Pierre Auger Observatory (Swain): The Pierre Auger Observatory makes use of the one accelerator bigger than the LHC-the one that gives us cosmic rays from intergalactic space. Currently taking data with a fully instrumented detector covering 3000 square kilometers.
