Ultrasonic attenuation in a pseudogapped superconductor

A. V. Shtyk, M. V. Feigel'man

We develop a theory of ultrasound decay rate $α$ in a model of a superconductor with a large pseudogap $Δ_{P}$ , and show that at low temperatures ( $T ≪ T_{c}$ ) the magnitude of the d…

Electrons at the monkey saddle: a multicritical Lifshitz point

Alex Shtyk, Garry Goldstein, Claudio Chamon

We consider 2D interacting electrons at a monkey saddle with dispersion $\propto p_{x}^{3} - 3 p_{x} p_{y}^{2}$ . Such a dispersion naturally arises at the multicritical Lifshitz point when three…
