Topological Surface-plasmon-polaritons on Corrugated Metal-dielectric Surfaces

Thomas Benjamin Smith, Coskun Kocabas, Alessandro Principi

We study topological surface-plasmon-polaritons at optical frequencies in diffraction gratings formed by bipartite corrugated metal-dielectric gratings. To do so we implement the t…

Thermal transport in compensated semimetals: a mystery explained

Mohammad Zarenia, Alessandro Principi, Giovanni Vignale

It is well known that the electronic thermal conductivity of clean compensated semimetals can be greatly enhanced over the electric conductivity by the availability of an ambipolar…

Observation of giant and tuneable thermal diffusivity of Dirac fluid at room temperature

Alexander Block, Alessandro Principi, Niels C. H. Hesp +8

Conducting materials typically exhibit either diffusive or ballistic charge transport. However, when electron-electron interactions dominate, a hydrodynamic regime with viscous cha…

Eccentric Corbino FET in magnetic field: a highly tunable photodetector

Bailey Winstanley, Henning Schomerus, Alessandro Principi

We study gated field effect transistors (FETs) with an eccentric Corbino-disk geometry, such that the drain spans its circumference while the off-center inner ring acts as a source…

Tunneling spectroscopy as a probe of fractionalization in 2D magnetic heterostructures

Matteo Carrega, Ivan J. Vera-Marun, Alessandro Principi

In this paper we develop the theory for 2D-to-2D tunneling spectroscopy aided by magnetic or quantum-order excitations, and apply it to the description of van-der-Waals heterostruc…

Emergent Non-Hermitian Edge Polarisation in an Hermitian Tight-binding Model

Thomas Benjamin Smith, Alessandro Principi

We study a bipartite Kronig-Penney model with negative Dirac-delta potentials that may be used, amongst other models, to interpret plasmon propagation in nanoparticle arrays. Such…
