Speaker: Amit Ghosal (Indian Institute of Science Education and Research Kolkata)
Orbital magnetic field and strong disorder weaken superconducting correlations acting individually on a type-II s-wave superconductor. The Abrikosov vortex lattice, resulting from the applied magnetic field, melts with an increase of the strength of the field, turning the system into a metal.... Read More »

Physics 298
Speaker: Thomas Banks (Rutgers University)
I will discuss an approximate equation for the two-point charge density correlation of the homogeneous electron fluid based on the large N expansion of this model. Large N considerations also lead to a conjecture about a colloidal phase in between the Wigner-crystal and fluid phases as first... Read More »

Physics 298
Speaker: Prof. Mathew Baumgart (Arizona State University)
In this letter we show that for observables which involve the measurement of weak charge in final states in hadronic collisions, the standard parton model picture breaks down at scales well above the weak scale due to non-factorizable electroweak corrections at leading order in the power expansion...

Physics 298
Speaker: Tapan Nayak (CERN)
For only a few millionths of a second after the Big Bang, our universe consisted of a hot and dense soup of quarks and gluons, which cooled down very quickly to form protons, neutrons, and other such normal nuclear matter. The discovery and characterization of this new phase of matter called the... Read More »

LSRC B101 Love Auditorium
Speaker: Nigel Lockyer (Fermilab)
"Neutrinos are Everywhere: Towards a New Understanding of the Quantum Universe" Neutrinos are the most numerous matter particles in the universe, but the least understood. The peculiar properties of neutrinos suggest connections to many of the big mysteries of particle physics, including the... Read More »

LSRC B101 Love Auditorium
FROM BIOLOGY IN THE 1960'S TO DISCOVERY OF THE HIGGS BOSON The symposium reviews the major discoveries that led to the construction of the Standard Model of elementary particle physics from its inception in the 1960's to a culmination with the discovery of the Higgs boson in 2012. It will conclude... Read More »

Physics 130
Speaker: Katia Bertoldi (Harvard)
"Kirigami-Inspired Metamaterials - from Morphable Structures to Soft Robots" In the search for materials with new properties, there have been great advances in recent years aimed at the construction of mechanical systems whose behaviour is governed by structure, rather than composition. Through... Read More »

Physics 298
Speaker: Benjamin Hunt (Carnegie Mellon University)
The physics of superconductors in reduced dimensions - two in particular - is related to such varied phenomena as high-temperature superconductivity, topological superconductivity, and the paradigmatic quantum phase transition, the superconductor-insulator transition. The discovery of graphene has... Read More »

Speaker: Andrea Shindler (MSU)
The electric dipole moments (EDM) of the nucleon (neutron or proton)is a very sensitive probe of CP-violation.The current bound on the neutron EDM strongly constrains many models of beyond-the-Standard Model (BSM) physics.At the current experimental accuracy, a nonzero nucleon EDM cannot be...
