Electronic bistability, discontinuous switching and stochasticity in a two-dimensional semiconductor
S. Jana, M. Kravtsov, A. Ermakov +11
Bistability - two stable electronic states under the same bias - underlies switching and memory, but is usually absent in transistors and must be engineered through material means:…

Spin and Charge Transport Mediated by Fractionalized Excitations
Alexey Ermakov, Alessandro Principi
We study charge and spin transport in systems composed of itinerant electrons and localized magnetic moments of a Kitaev quantum spin liquid (QSL) phase. For example, $α-{\rm RuCl…

Extreme electron-hole drag and negative mobility in the Dirac plasma of graphene
L. A. Ponomarenko, Alessandro Principi, A. D. Niblett +13
Coulomb drag between adjacent electron and hole gases has attracted considerable attention, being studied in various two-dimensional systems, including semiconductor and graphene h…
