Add   How many surface modes does one see on the boundary of a Dirac material?
Authors: Kurkov, Maxim | Vassilevich, Dmitri V.
Source: Physical Review Letters. 2020. Vol. 124, № 17. P. 176802-1-176802-5
Type: статьи в журналах
Date: 2020
Description: We present full expressions for the surface part of polarization tensor of a Dirac fermion confined in a half-space in 3+1 dimensions. We compare this tensor to the polarization tensor of eventual sur ... More
Add   Quantum Dirac fermions in a half-space and their interaction with an electromagnetic field
Authors: Fialkovsky, Ignat | Kurkov, Maxim | Vassilevich, Dmitri V.
Source: Physical Review D. 2019. Vol. 100, № 4. P. 045026-1-045026-13
Type: статьи в журналах
Date: 2019
Description: We study the polarization tensor of a Dirac field in (3 þ 1) dimensions confined to a half-space—a problem motivated by applications to the condensed matter physics, and to topological insulators in p ... More
Add   Gravitational parity anomaly with and without boundaries
Authors: Kurkov, Maxim | Vassilevich, Dmitri V.
Source: Journal of high energy physics. 2018. № 3. P. 072 (1-16)
Type: статьи в журналах
Date: 2018
Description: In this paper we consider gravitational parity anomaly in three and four dimensions. We start with a re-computation of this anomaly on a 3D manifold without boundaries and with a critical comparison o ... More
