Fractional quantum Hall effect in strained graphene: stability of Laughlin states in disordered (pseudo)magnetic fields
Andrey A. Bagrov, Alessandro Principi, Mikhail I. Katsnelson
We address the question of the stability of the (fractional) quantum Hall effect (QHE) in presence of pseudomagnetic disorder generated by mechanical deformations of a graphene she…
Super-Planckian electron cooling in a van der Waals stack
Alessandro Principi, Mark B. Lundeberg, Niels C. H. Hesp +3
Radiative heat transfer (RHT) between macroscopic bodies at separations that are much smaller than the thermal wavelength is ruled by evanescent electromagnetic modes and can be or…
Hall viscosity and electromagnetic response of electrons in graphene
Mohammad Sherafati, Alessandro Principi, Giovanni Vignale
We derive an analytic expression for the geometric Hall viscosity of non-interacting electrons in a single graphene layer in the presence of a perpendicular magnetic field. We show…
Edge pseudo-magnetoplasmons
Alessandro Principi, Mikhail I. Katsnelson, Giovanni Vignale
We study the properties of edge plasmons in two-component electron liquids in the presence of pseudomagnetic fields, which have opposite signs for the two different electronic popu…
Self-induced glassiness and pattern formation in spin systems subject to long-range interactions
Alessandro Principi, Mikhail I. Katsnelson
We study the glass formation in two- and three-dimensional Ising and Heisenberg spin systems subject to competing interactions and uniaxial anisotropy with a mean-field approach. I…
Ultra-confined acoustic THz graphene plasmons revealed by photocurrent nanoscopy
Pablo Alonso-Gonzalez, Alexey Y. Nikitin, Yuanda Gao +14
Terahertz (THz) fields are widely applied for sensing, communication and quality control. In future applications, they could be efficiently confined, enhanced and manipulated - wel…
