Stellar Wind of Components of Detached Binary Systems
A. V. Tutukov, A. V. Sobolev
The paper is devoted to the consideration of the role of the donor stellar wind in the matter exchange between the components of detached binary systems. A classification of close…
Spectral asymptotics of pseudodifferential operators with discontinuous symbols
Alexey Derkach, Alexander V. Sobolev
We study discrete spectrum of self-adjoint Weyl pseudodifferential operators with discontinuous symbols of the form where is the indicator of a domain in $Ω\subset…
Multifunctional 2d infrared photodetectors enabled by asymmetric singular metasurfaces
Valentin Semkin, Aleksandr Shabanov, Kirill Kapralov +9
Two-dimensional materials offering ultrafast photoresponse suffer from low intrinsic absorbance, especially in the mid-infrared wavelength range. Challenges in 2d material doping f…
The Fermionic Entanglement Entropy and Area Law for the Relativistic Dirac Vacuum State
Felix Finster, Magdalena Lottner, Alexander V. Sobolev
We consider the fermionic entanglement entropy for the free Dirac field in a bounded spatial region of Minkowski spacetime. In order to make the system ultraviolet finite, a regula…
