Quantum anomalies and linear response theory
"... Abstract. The analysis of diffusive energy spreading in quantized chaotic driven systems, leads to a universal paradigm for the emergence of a quantum anomaly. In the classical approximation a driven chaotic system exhibits stochasticlike diffusion in energy space with a coefficient D that is propo ..."

A QUANTUM ANOMALY FOR RIGID PARTICLES
, 1992
"... Canonical quantisation of rigid particles is considered paying special attention to the restriction on phase space due to causal propagation. A mixed Lorentzgravitational anomaly is found in the commutator of Lorentz boosts with worldline reparametrisations. The subspace of gauge invariant physica ..."

Quantum anomalies and some recent developments 1
, 902
"... Some of the developments related to quantum anomalies and path integrals during the past 10 years are briefly discussed. The covered subjects include the issues related to the local counter term in the context of 2dimensional path integral bosonization and the treatment of chiral anomaly and index ..."

Quantum anomalies for generalized Euclidean TaubNUT metrics
"... We investigate quantum anomalies for generalized Euclidean TaubNUT metrics which admit hidden symmetries analogous to the RungeLenz vector of the Keplertype problem. We review results which show that the appearance of gravitational anomalies is connected with the absence of KillingYano tensors f ..."

Quantum anomaly and geometric phase; their basic differences
, 2006
"... It is sometimes stated in the literature that the quantum anomaly is regarded as an example of the geometric phase. Though there is some superficial similarity between these two notions, we here show that the differences bewteen these two notions are more profound and fundamental. As an explicit exa ..."

KodairaSpencer theory of gravity and exact results for quantum string amplitudes
 Commun. Math. Phys
, 1994
"... We develop techniques to compute higher loop string amplitudes for twisted N = 2 theories with ĉ = 3 (i.e. the critical case). An important ingredient is the discovery of an anomaly at every genus in decoupling of BRST trivial states, captured to all orders by a master anomaly equation. In a particu ..."

"... We study the possible quantum anomaly for the transverse WardTakahashi relations in four dimensional gauge theories based on the method of computing the axialvector and the vector current operator equations. In addition to the wellknown anomalous axialvector divergence equation (the AdlerBellJ ..."

RELATIVISTIC RIGID PARTICLES: CLASSICAL TACHYONS AND QUANTUM ANOMALIES
, 1992
"... Causal rigid particles whose action includes an arbitrary dependence on the worldline extrinsic curvature are considered. General classes of solutions are constructed, including causal tachyonic ones. The Hamiltonian formulation is developed in detail except for one degenerate situation for which o ..."

quantisation of the generic case is performed paying special attention to the phase space restriction due to causal propagation. A mixed Lorentzgravitational anomaly is found in the commutator of Lorentz boosts with worldline reparametrisations. The subspace of gauge invariant physical states is therefore
