The mechanism of electrical conduction in glassy semiconductors
Arkady Kurnosov, Vassiliy Lubchenko
We argue that the dominant charge carrier in glassy semiconducting alloys is a compound particle in the form of an electron or hole bound to an intimate pair of topological lattice…
Optical Kinetic Theory of Nonlinear Multi-mode Photonic Networks
Arkady Kurnosov, Lucas J. Fernández-Alcázar, Alba Y. Ramos +2
Recent experimental developments in multimode nonlinear photonic circuits (MMNPC), have motivated the development of an optical thermodynamic theory that describes the equilibrium…
Nonlinear Wavepacket Dynamics in Proximity to a Stationary Inflection Point
Serena Landers, Arkady Kurnosov, William Tuxbury +2
A stationary inflection point (SIP) in the Bloch dispersion relation of a periodic waveguide is an exceptional point degeneracy where three Bloch eigenmodes coalesce forming the so…
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…
Reconfigurable Enhancement of Actuation Forces by Engineered Losses in non-Hermitian Metamaterials
Abhishek Gupta, Arkady Kurnosov, Tsampikos Kottos +1
While boosting signals with amplification mechanisms is a well established approach, attenuation mechanisms are typically considered an anathema because they degrade the efficiency…
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…
