Resolving the vDVZ and Strong Coupling Problems in Massive Gravity and Bigravity
Gregory Gabadadze, Daniel Older, David Pirtskhalava
As is well known, both massive gravity and bigravity exhibit the linear van Dam-Veltman-Zakharov (vDVZ) discontinuity that is cured classically by the nonlinear Vainshtein mechanis…

Observation of a Topological Insulator Dirac Cone Reshaped by Non-magnetic Impurity Resonance
Lin Miao, Yishuai Xu, Wenhan Zhang +10
The massless Dirac electrons found at topological insulator surfaces are thought to be influenced very little by weak, non-magnetic disorder. However, a resonance effect of strongl…
