Reply to "Comment on "Electric conductivity in graphene: Kubo model versus a nonlocal quantum field theory model"" (ArXiv:2506.10792v2)
Pablo Rodriguez-Lopez, Jian-Sheng Wang, Mauro Antezza
In the Comment by Bordag et al. [Phys. Rev. B 113, 207401 (2026) and ArXiv:2506.10792], concerns are raised regarding the validity of the results presented in [Phys. Rev. B 111, 11…
A topological field-effect memristor
Manuel Meyer, Selena Barragan, Sergey Krishtopenko +13
Overcoming the limitations of the von Neumann architecture requires new computational paradigms capable of solving complex problems efficiently. Quantum and neuromorphic computing…
Quantum spin Hall effect in III-V semiconductors at elevated temperatures: advancing topological electronics
Manuel Meyer, Jonas Baumbach, Sergey Krishtopenko +13
The quantum spin Hall effect (QSHE), a hallmark of topological insulators, enables dissipationless, spin-polarized edge transport and has been predicted in various two-dimensional…
Isofrequency spin-wave imaging using color center magnetometry for magnon spintronics
Samuel Mañas-Valero, Yasmin C. Doedes, Artem Bondarenko +7
Magnon spintronics aims to harness spin waves in magnetic films for information technologies. Color center magnetometry is a promising tool for imaging spin waves, using electronic…
Many-particle hybridization of optical transitions from zero-mode Landau levels in HgTe quantum wells
S. Ruffenach, S. S. Krishtopenko, A. V. Ikonnikov +6
We present far-infrared magnetospectroscopy measurements of a HgTe quantum well in the inverted band structure regime over the temperature range of 2 to 60 K. The particularly low…
Positive Terahertz Photoconductivity in CdHgTe Under Hydrostatic Pressure
Ivan Yahniuk, Dmitriy A. Kozlov, Mariya D. Moldavskaya +10
Positive terahertz photoconductivity is observed at room temperature in CdHgTe thin films with different Cd contents. We show that electron gas heating caused by Drude-like absorpt…
