s = 1.96 TeV at the Fermilab Tevatron collider are discussed. For the inclusive searches, events with multiple jets of hadrons and large missing transverse energy in the final state are studied within the framework of minimal supergravity and assuming R-parity conservation. Searches for the scalar top quark are studied in two final state topologies: with events of two charm jets and large missi...

We report on experimental observations that the two-fluid Hall dynamo plays an important role in plasma relaxation. Measurements of the Hall effect during relaxation are made in the plasma core and edge. The Hall dynamo is found to be small at the edge ( ! r /a " 0.85) but increases substantially towards the interior (r/a=0.82) as measured by probes. In the high-temperature plasma core (r/a=0.3...

For each simply-laced Dynkin graph ∆ we realize the simple complex Lie algebra of type ∆ as a quotient algebra of the complex degenerate composition Lie algebra L(A) 1 of a domestic canonical algebra A of type ∆ by some ideal I of L(A) 1 that is defined via the Hall algebra of A, and give an explicit form of I. Moreover, we show that each root space of L(A) 1 /I has a basis given by the coset o...

was described in terms of the so-called Hall algebra U+X of the category of coherent sheaves on an elliptic curve X (defined over a finite field Fq). This Hall algebra turns out to be a two-parameter deformation of ΛΛ, the two deformation parameters being the Frobenius eigenvalues σ, σ̄ of the particular elliptic curve. In fact, the structure constants for U+X are Laurent polynomials in σ and σ̄,...

We show that gated bilayer graphene hosts a strong topological insulator (TI) phase in the presence of Rashba spin-orbit (SO) coupling. We find that gated bilayer graphene under preserved time-reversal symmetry is a quantum valley Hall insulator for small Rashba SO coupling λ(R), and transitions to a strong TI when λ(R)>√[U(2)+t(⊥)(2)], where U and t(⊥) are, respectively, the interlayer potenti...
