Structure Formation in the Early UniverseJun 23 2009The standard theory of cosmic structure formation posits that the present-day rich structure of the Universe developed through gravitational amplification of tiny matter density fluctuations generated in its very early history. Recent observations of ... More
On non-abelian Lubin-Tate theory via vanishing cyclesApr 21 2004May 18 2010We give a purely local proof, in the depth 0 case, of the result by Harris-Taylor which asserts that the local Langlands correspondence for GL_n over a p-adic field K realizes itself inside the vanishing cycle cohomology of the deformation space of formal ...

Multi-hadron final states in RPV supersymmetric models with extra mattersMay 15 2014The gluino mass has been constrained by various search channels at the LHC experiments and the recent analyses are even sensitive to the cases where gluinos decay to quarks at the end of the decay chains through the baryonic RPV operator. We argue that ... More
Search for Sphalerons: IceCube vs. LHCMar 21 2016We discuss the observability of neutrino-induced sphaleron transitions in the IceCube detector, encouraged by a recent paper by Tye and Wong (TW), which argued on the basis of a Bloch wave function in the periodic sphaleron potential that such transitions ...

Dynamics of bubbles in a two-component Bose-Einstein condensateNov 25 2010The dynamics of a phase-separated two-component Bose-Einstein condensate are investigated, in which a bubble of one component moves through the other component. Numerical simulations of the Gross--Pitaevskii equation reveal a variety of dynamics associated ... More
