Anomalous chiral magnetic effect in time reversal symmetry breaking Weyl semimetals
Long Liang
We propose a mechanism to generate dissipationless current in time reversal symmetry breaking Weyl semimetals through the anomalous chiral magnetic effect (ACME). The ACME current…
Axial Magnetoelectric Effect in Dirac semimetals
Long Liang, P. O. Sukhachov, A. V. Balatsky
We propose a mechanism to generate a static magnetization via {\em axial magnetoelectric effect} (AMEE). Magnetization appears as…
Topological magnetotorsional effect in Weyl semimetals
Long Liang, Teemu Ojanen
In this work we introduce a thermal magnetotorsional effect (TME) as a novel topological response in magnetic Weyl semimetals. We predict that magnetization gradients perpendicular…
Dynamical slave-boson mean-field study of the Mott transition in the Hubbard model in the large- limit
Sen Zhou, Long Liang, Ziqiang Wang
The Mott metal-insulator transition in the Hubbard model is studied by constructing a dynamical slave-boson mean-field theory in the limit of large lattice coordination number …
Curved spacetime theory of inhomogeneous Weyl materials
Long Liang, Teemu Ojanen
We show how the universal low-energy properties of Weyl semimetals with spatially varying time-reversal (TR) or inversion (I) symmetry breaking are described in terms of chiral fer…
Superfluid weight and Berezinskii-Kosterlitz-Thouless transition temperature of twisted bilayer graphene
Aleksi Julku, Teemu J. Peltonen, Long Liang +2
We study superconductivity of twisted bilayer graphene with local and non-local attractive interactions. We obtain the superfluid weight and Berezinskii-Kosterlitz-Thouless (BKT) t…
