Two-Loop Turbulent Helical Magnetohydrodynamics: Large-Scale Dynamo and Energy Spectrum
We present a two-loop field-theoretic analysis of incompressible helical magnetohydrodynamics (MHD) in fully developed stationary turbulence. A key feature of helical MHD is the appearance of an infrared-unstable ``mass-like'' term in the loop diagrams of the magnetic response function. Physically, this term corresponds to the relevant perturbation of the Joule damping, proportional to $\boldsymbol{\nabla} \times \boldsymbol{b}$ ($\boldsymbol{b} =$ magnetic field). Its presence destabilizes the…

Kirjutasin ERRi artikli. Pole vist kunagi nii kiiresti ühte artiklit kirjutanud, tavaliselt kulub selleks palju rohkem aega. Põhjus selles, et lugesin Kristjan Porti arvamust Novaatoris ning mõtlesin, et miks see "pimeda keskaja" müüt ka ei kao. Sellest on ju nii palju juttu olnud. Meil oli eelmisel semestril TÜs ka ülikoolimõtte ajaloo kursus, kus sai pikalt tegeletud keskaja ning varauusaja ülikoolide ajalooga ning eriti just sellel taustal tundus, et on vaja ikkagi midagi omalt …

High-temperature helical edge states in BiSbTeSe$_2$/graphene van der Waals heterostructure
Van der Waals heterostructures have been used to tailor atomic layers into various artificial materials through interactions at heterointerfaces. The interplay between the band gap created by the band folding of the interfacial potential and the band inversion driven by enhanced spin-orbit interaction (SOI) through band hybridization enables us to realize a two-dimensional topological insulator (2D-TI). Here we report the realization of graphene 2D-TIs by epitaxial growth of three-dimensional t…

Higher Chern bands in helical homotrilayer transition metal dichalcogenides
We propose helically twisted homotrilayer transition metal dichalcogenides as a platform for realizing correlated topological phases of matter with higher and tunable Chern numbers. We show that a clear separation of scales emerges for small twist angles, allowing us to derive a low-energy continuum model that captures the physics within moiré-scale domains. We identify regimes of twist angle and displacement field for which the highest-lying hole band is isolated from other bands and is topol…
