Tunneling density of states, correlation energy, and spin polarization in the fractional quantum Hall regime
Gaurav Chaudhary, Dmitry K. Efimkin, Allan H. MacDonald
We derive exact sum-rules that relate the tunneling density of states (TDOS) of spinful electrons in the fractional quantum Hall (FQH) regime to the spin-dependent many body ground…
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…
Amperean Pairing at the Surface of Topological Insulators
Mehdi Kargarian, Dmitry K. Efimkin, Victor Galitski
The surface of a 3D topological insulator is described by a helical electron state with the electron's spin and momentum locked together. We show that in the presence of ferromagne…
Radio Frequency Tunable Oscillator Device Based on SmB6 Microcrystal
A. Stern, D. K. Efimkin, V. Galitski +2
Radio frequency tunable oscillators are vital electronic components for signal generation, characterization, and processing. They are often constructed with a resonant circuit and…
