Giant magnetoresistance of Dirac plasma in high-mobility graphene
Na Xin, James Lourembam, P. Kumaravadivel +12
The most recognizable feature of graphene's electronic spectrum is its Dirac point around which interesting phenomena tend to cluster. At low temperatures, the intrinsic behavior i…
Non-conservation of the valley density and its implications for the observation of the valley Hall effect
Alexander Kazantsev, Amelia Mills, Eoin O'Neill +3
We show that the conservation of the valley density in multivalley insulators is broken in an unexpected way by the electric field that drives the valley Hall effect. This implies…
On the origin of Abrikosov's quantum linear magnetoresistance
Alexander Kazantsev, Alexey Berdyugin, Andre Geim +1
Compensated semimetals with Weyl spectra are predicted to exhibit unsaturated linear growth of their resistivity in quantizing magnetic fields. This so-called quantum linear magnet…
Two-loop renormalization of the matter superfields and finiteness of supersymmetric gauge theories regularized by higher derivatives
Alexander Kazantsev, Konstantin Stepanyantz
The two-loop anomalous dimension of the chiral matter superfields is calculated for a general supersymmetric gauge theory regularized by higher covariant derivatives.…
New form of the exact NSVZ -function: the three-loop verification for terms containing Yukawa couplings
A. E. Kazantsev, V. Yu. Shakhmanov, K. V. Stepanyantz
We investigate a recently proposed new form of the exact NSVZ -function, which relates the -function to the anomalous dimensions of the quantum gauge superfield, of the Fadde…
Exact results in explicit three-loop calculations using higher derivatives for SQCD
A. L. Kataev, A. E. Kazantsev, K. V. Stepanyantz
We calculate the three-loop Adler -function of SQCD regularized by higher covariant derivatives and find the subtraction scheme in which the exact NSVZ-like relatio…

A. L. Kataev, A. E. Kazantsev, K. V. Stepanyantz
We calculate the Adler -function for SQCD in the three-loop approximation using the higher covariant derivative regularization and the NSVZ-like subtraction scheme.…
One-loop polarization operator of the quantum gauge superfield for SYM regularized by higher derivatives
A. E. Kazantsev, M. B. Skoptsov, K. V. Stepanyantz
We consider the general supersymmetric gauge theory with matter, regularized by higher covariant derivatives without breaking the BRST invariance, in the massless limi…
One-loop divergences in non-Abelian supersymmetric theories regularized by BRST-invariant version of the higher derivative regularization
S. S. Aleshin, A. E. Kazantsev, M. B. Skoptsov +1
We consider a general non-Abelian renormalizable supersymmetric gauge theory, regularized by higher covariant derivatives without breaking the BRST invariance, and cal…
Relation between two-point Green functions of SQED with flavors, regularized by higher derivatives, in the three-loop approximation
A. E. Kazantsev, K. V. Stepanyantz
We verify the identity which relates the two-point Green functions of SQED with flavors, regularized by higher derivatives, by explicit calculations in the three…
