Monopoles, Dirac strings and generalised symmetries

Journal of High Energy Physics
Dirac’s formulation of magnetic monopoles is shown to be equivalent to Maxwell theory coupled to 2-form gauge fields so that it has a local 1-form symmetry, with the 2-form gauge fields given in terms of the 2-form current densities associated with the ...

Two‐Dimensional Materials as a Multiproperty Sensing Platform

Advanced Functional Materials, EarlyView.
Various sensing modalities enabled and/or enhanced by two‐dimensional (2D) materials are reviewed. The domains considered for sensing include: 1) optoelectronics, 2) quantum defects, 3) scanning probe microscopy, 4) nanomechanics, and 5) bio‐ and chemosensing.

Chern-Simons modification of fluid mechanics

Physics Letters B
We show that the hydrodynamics of the perfect fluid admits a natural modification that incorporates a chiral gravitational anomaly (also known as a mixed gauge-gravity anomaly) alongside the chiral current anomaly.

Hydrodynamics of topological Dirac semi-metals with chiral and ℤ2 anomalies

Journal of High Energy Physics, 2018
We consider the hydrodynamical model of topological Dirac semi-metal possessing two Dirac nodes separated in momentum space along a rotation axis. It has been argued that the system in question, except the chiral anomaly, is endowed with the other one ℤ2.

Unprecedented Spin‐Lifetime of Itinerant Electrons in Natural Graphite Crystals

Advanced Functional Materials, EarlyView.
Graphite exhibits extraordinary spintronic potential, with electron spin lifetimes reaching 1,000 ns at room temperature ‐ over 100 times longer than graphene‐based devices. Magnetic resonance spectroscopy reveals strong anisotropy: out‐of‐plane spins live 50 times longer than their in‐plane counterparts.

Time-reversal anomalies of QCD3 and QED3

Journal of High Energy Physics
Anomalies of global symmetry provide powerful tool to constrain the dynamics of quantum systems, such as anomaly matching in the renormalization group flow and obstruction to symmetric mass generation.

Lieb-Schultz-Mattis anomalies as obstructions to gauging (non-on-site) symmetries

SciPost Physics
We study 't Hooft anomalies of global symmetries in 1+1d lattice Hamiltonian systems. We consider anomalies in internal and lattice translation symmetries.

Generalized ’t Hooft anomalies on non-spin manifolds

Journal of High Energy Physics, 2020
We study the mixed anomaly between the discrete chiral symmetry and general baryon-color-flavor (BCF) backgrounds in SU(N c ) gauge theories with N f flavors of Dirac fermions in representations ℛ c of N -ality n c , formulated on non-spin manifolds.

Space-time dependent couplings in N=1 SUSY gauge theories: Anomalies and Central Functions

, 2005
We consider N=1 supersymmetric gauge theories in which the couplings are allowed to be space-time dependent functions. Both the gauge and the superpotential couplings become chiral superfields.
