Wigner-Weyl calculus in Keldysh technique
C. Banerjee, I. V. Fialkovsky, M. Lewkowicz +2
We discuss the non-equilibrium dynamics of condensed matter/quantum field systems in the framework of Keldysh technique. In order to deal with the inhomogeneous systems we use the…
The type II Weyl semimetals at low temperatures: chiral anomaly, elastic deformations, zero sound
M. A. Zubkov, M. Lewkowicz
We consider the properties of the type II Weyl semimetals at low temperatures basing on the particular tight - binding model. In the presence of electric field directed along the l…
Nonlocal electrodynamics in Weyl semi-metals
B. Rosenstein, H. C. Kao, M. Lewkowicz
Recently synthesized 3D materials with Dirac spectrum exhibit peculiar electric transport qualitatively different from its 2D analogue, graphene. Neglecting impuritiy scattering, t…
Two distinct ballistic processes in graphene at Dirac point
M. Lewkowicz, B. Rosenstein, D. Nghiem
The dynamical approach is applied to ballistic transport in mesoscopic graphene samples of length L and contact potential U. At times shorter than both relevant time scales, the fl…
Signature of Schwinger's pair creation rate via radiation generated in graphene by strong electric current
M. Lewkowicz, H. C. Kao, B. Rosenstein
Electron - hole pairs are copuously created by an applied electric field near the Dirac point in graphene or similar 2D electronic systems. It was shown recently that for sufficien…
Ballistic transport, chiral anomaly and emergence of the neutral electron - hole plasma in graphene
H. C. Kao, M. Lewkowicz, B. Rosenstein
The process of coherent creation of particle - hole excitations by an electric field in graphene is quantitatively described using a dynamic "first quantized" approach. We calculat…
