Adiabatic monoparametric autonomous motors enabled by self-induced nonconservative forces
Arkady Kurnosov, Lucas J. Fernández-Alcázar, Raúl Bustos-Marún +1
Archetypal motors produce work when two slowly varying degrees of freedom (DOF) move around a closed loop of finite area in the parameter space. Here, instead, we propose a simple…

Temperature-driven narrowing of the insulating gap as a precursor of the insulator-to-metal transition: Implications for the electronic structure of solids
Vassiliy Lubchenko, Arkady Kurnosov
We present a microscopic picture rationalizing the surprisingly steep decrease of the band gap with temperature in insulators, crystalline or otherwise. The gap narrowing largely r…
