Renormalised spectral flows

SciPost Physics Core, 2023
We derive renormalised finite functional flow equations for quantum field theories in real and imaginary time that incorporate scale transformations of the renormalisation conditions, hence implementing a flowing renormalisation. The flows are manifestly finite in general non-perturbative truncation schemes also for regularisation schemes that do not ...

Operator Integrals, Spectral Shift, and Spectral Flow [PDF]

Canadian Journal of Mathematics, 2009
Abstract. We present a new and simple approach to the theory of multiple operator integrals that applies to unbounded operators affiliated with general von Neumann algebras. For semifinite von Neumann algebras we give applications to the Fréchet differentiation of operator functions that sharpen existing results, and establish the Birman–Solomyak ...

Panel Design and Optimization for High‐Dimensional Immunophenotyping Assays Using Spectral Flow Cytometry

Current Protocols in Cytometry, 2020
Technological advances in fluorescence flow cytometry and an ever‐expanding understanding of the complexity of the immune system have led to the development of large (20+ parameters) flow cytometry panels.

SKYRMIONS, SPECTRAL FLOW AND PARITY DOUBLES [PDF]

International Journal of Modern Physics A, 1999
It is well-known that the winding number of the Skyrmion can be identified as the baryon number. We show in this paper that this result can also be established using the Atiyah–Singer index theorem and spectral flow arguments. We argue that this proof suggests that there are light quarks moving in the field of the Skyrmion.

The Aharonov-Bohm effect for massless Dirac fermions and the spectral flow of Dirac type operators with classical boundary conditions [PDF]

, 2012
We compute, in topological terms, the spectral flow of an arbitrary family of self-adjoint Dirac type operators with classical (local) boundary conditions on a compact Riemannian manifold with boundary under the assumption that the initial and terminal ...

Spectral modeling of magnetohydrodynamic turbulent flows [PDF]

Physical Review E, 2008
We present a dynamical spectral model for Large Eddy Simulation of the incompressible magnetohydrodynamic (MHD) equations based on the Eddy Damped Quasi Normal Markovian approximation. This model extends classical spectral Large Eddy Simulations for the Navier-Stokes equations to incorporate general (non Kolmogorovian) spectra as well as eddy noise. We

$ L^2 $-Gradient flows of spectral functionals

Discrete and Continuous Dynamical Systems, 2023
We study the $L^2$-gradient flow of functionals $\mathcal F$ depending on the eigenvalues of Schrödinger potentials $V$ for a wide class of differential operators associated to closed, symmetric, and coercive bilinear forms, including the case of all the Dirichlet forms (as for second order elliptic operators in Euclidean domains or Riemannian ...

Spectral flow and variational bifurcation [PDF]

Journal of Fixed Point Theory and Applications
We show that the principle “nonvanishing of spectral flow of the linearization along the trivial branch entails bifurcation of nontrivial solutions”, established in Fitzpatrick et al.

More AdS_3 correlators [PDF]

, 2014
We compute three-point functions for the $SL(2,\mathbb R)$-WZNW model. After reviewing the case of the two-point correlator, we compute spectral flow preserving and nonpreserving correlation functions in the space-time picture involving three vertex ...

Knizhnik-Zamolodchikov equations and spectral flow in AdS3 string theory [PDF]

, 2005
I generalize the Knizhnik-Zamolodchikov equations to correlators of spectral flowed fields in AdS3 string theory. If spectral flow is preserved or violated by one unit, the resulting equations are equivalent to the KZ equations.
