Manifestations of (2 + 1)d chiral anomaly in a graphene plate
Physics Letters BInspired by the Dirac model of graphene, we consider a (2+1)-dimensional fermionic system in which fermions are described by four-component spinors. These fermions are proposed to interact with an electromagnetic field originating from a four-dimensional

Advanced Science, EarlyView.We combine altermagnet with topological insulators and subject the structure to Floquet driving. This breaks time‐reversal symmetry and creates a new type of higher‐order topological insulator. Its key feature is the emergence of programmable “0/π‐corner modes” that can be controlled by magnetic field direction, offering a novel dynamic platform for ...

Exploring the World of Double Nanohoops
Angewandte Chemie International Edition, EarlyView.As two conjugated nanohoops covalently linked by a central unit, double nanohoops are a relatively new class of strained nanocarbons with different properties to single nanohoops. This review gives an overview of all reported double nanohoops, categorizing their structures, syntheses, and discussing properties and applications. Creativity and synthetic

NEW APPLICATIONS OF THE CHIRAL ANOMALY [PDF]
, 2000 We describe consequences of the chiral anomaly in the theory of quantum wires, the (quantum) Hall effect, and of a four-dimensional cousin of the Hall effect. We explain which aspects of conductance quantization are related to the chiral anomaly. The four-dimensional analogue of the Hall effect involves the axion field, whose time derivative can be ...

Anomalous Magnetization Dynamics After Dual Optical Excitation
Advanced Physics Research, EarlyView.We demonstrate that dual‐pump femtosecond excitation in copper leads to a pronounced, non‐additive change in spin and orbital relaxation dynamics compared to single‐pulse excitation. Time‐resolved magneto‐optical Kerr effect measurements reveal a 2.5× increase in angular momentum decay time, highlighting a new route to ultrafast control of electronic ...

Chiral magnetic waves in strongly coupled Weyl semimetals
Journal of High Energy PhysicsPropagating chiral magnetic waves (CMW) are expected to exist in chiral plasmas due to the interplay between the chiral magnetic and chiral separation effects induced by the presence of a chiral anomaly. Unfortunately, it was pointed out that, because of

Berry phase theory of planar Hall effect in topological insulators
Scientific Reports, 2018 The appearance of negative longitudinal magnetoresistance (LMR) in topological semimetals such as Weyl and Dirac semimetals is understood as an effect of chiral anomaly, whereas such an anomaly is not well-defined in topological insulators. Nevertheless,

Quasinormal modes of charged magnetic black branes & chiral magnetic transport
Journal of High Energy Physics, 2017 We compute quasinormal modes (QNMs) of the metric and gauge field perturbations about black branes electrically and magnetically charged in the Einstein-Maxwell-Chern-Simons theory. By the gauge/gravity correspondence, this theory is dual to a particular
