Universal Renormalons in Principal Chiral Models

Falk Bruckmann, Matthias Puhr

Perturbative expansions in many physical systems yield 'only' asymptotic series which are not even Borel resummable. Interestingly, the corresponding ambiguities point to nonpertur…

A Lattice Study of Renormalons in Asymptotically Free Sigma Models

Matthias Puhr, Falk Bruckmann

In general, perturbative expansions of observables in powers of the coupling constant in quantum field theories are asymptotic series. In many cases it is possible to apply resumma…

The Chiral Separation Effect in quenched finite-density QCD

M. Puhr, P. V. Buividovich

We present results of a study of the Chiral Separation Effect (CSE) in quenched finite-density QCD. Using a recently developed numerical method we calculate the conserved axial cur…

A numerical study of non-perturbative corrections to the Chiral Separation Effect in quenched finite-density QCD

M. Puhr, P. V. Buividovich

We demonstrate the non-renormalization of the Chiral Separation Effect (CSE) in quenched finite-density QCD in both confinement and deconfinement phases using a recently developed…

A numerical method to compute derivatives of functions of large complex matrices and its application to the overlap Dirac operator at finite chemical potential

M. Puhr, P. V. Buividovich

We present a method for the numerical calculation of derivatives of functions of general complex matrices. The method can be used in combination with any algorithm that evaluates o…

Chiral Magnetic Effect in finite-size samples of parity-breaking Weyl semimetals

S. N. Valgushev, M. Puhr, P. V. Buividovich

We study the static electric current due to the Chiral Magnetic Effect in samples of Weyl semimetals with slab geometry, where the magnetic field is parallel to the boundaries of t…
