Direct observation of surface state thermal oscillation in SmB6 oscillators
Brian Casas, Alex Stern, Dmitry K. Efimkin +2
SmB6 is a mixed valence Kondo insulator that exhibits a sharp increase in resistance following an activated behavior that levels off and saturates below 4K. This behavior can be ex…
Exciton-polarons in doped semiconductors in a strong magnetic field
Dmitry K. Efimkin, Allan H. MacDonald
In previous work we have argued that the optical properties of moderately doped two-dimensional semiconductors can be described in terms of excitons dressed by their interactions w…
Kinetic theory of dark solitons with tunable friction
Hilary M. Hurst, Dmitry K. Efimkin, I. B. Spielman +1
We study controllable friction in a system consisting of a dark soliton in a one-dimensional Bose-Einstein condensate coupled to a non-interacting Fermi gas. The fermions act as im…
