Correlated Insulator Moiré Bolometer
L. Elesin, A. L. Shilov, M. Kravtsov +14
Light incident on an insulator is generally not expected to turn it into a metal without invoking intense ultrafast excitation that leads to transient structural transitions. Here…
Probing the features of electron dispersion by tunneling between slightly twisted bilayer graphene sheets
Alexey A. Sokolik, Azat F. Aminov, Evgenii E. Vdovin +6
Tunneling conductance between two bilayer graphene (BLG) sheets separated by 2 nm-thick insulating barrier was measured in two devices with the twist angles between BLGs less than…
On the Connection of High-Resolution NMR Spectrum Mirror Symmetry With Spin System Properties
Dmitry A. Cheshkov, Dmitry O. Sinitsyn
A correlation between the symmetry of NMR spectra, including higher-order spectra, and the properties of the spin system has been established. It is shown that for a spectrum to be…
Broadband optical time-domain reflectometry for security analysis of quantum key distribution
Klim D. Bondar, Ivan S. Sushchev, Daniil D. Bulavkin +5
In this paper, we present a method for security analysis against the Trojan-horse attacks (THA) launched to a practical fiber-based quantum key distribution (QKD) system across a w…
Realistic vulnerabilities of decoy-state quantum key distribution
I. S. Sushchev, K. E. Bugai, S. N. Molotkov +6
We analyze realistic vulnerabilities of decoy-state quantum key distribution (QKD) arising from the combination of laser damage attack (LDA) and unambiguous state discrimination (U…
Limiting performance of graphene bilayer sub-terahertz detectors at large induced band gap
Elena I. Titova, Mikhail A. Kashchenko, Andrey V. Miakonkikh +8
Electrically induced junctions in graphene bilayer (GBL) have shown superior performance for detection of sub-THz radiation at cryogenic temperatures, especially upon electri…
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…
Generative inpainting of incomplete Euclidean distance matrices of trajectories generated by a fractional Brownian motion
Alexander Lobashev, Dmitry Guskov, Kirill Polovnikov
Fractional Brownian motion (fBm) features both randomness and strong scale-free correlations, challenging generative models to reproduce the intrinsic memory characterizing the und…
Anomalous terahertz photoconductivity caused by the superballistic flow of hydrodynamic electrons in graphene
M. Kravtsov, A. L. Shilov, Y. Yang +18
Light incident upon materials can induce changes in their electrical conductivity, a phenomenon referred to as photoresistance. In semiconductors, the photoresistance is negative,…
Selective damping of plasmons in coupled two-dimensional systems by Coulomb drag
Ilya Safonov, Aleksandr S. Petrov, Dmitry Svintsov
The Coulomb drag is a many-body effect observed in proximized low-dimensional systems. It appears as emergence of voltage in one of them upon passage of bias current in another. Th…
Fundamental limits of few-layer NbSe microbolometers at terahertz frequencies
K. Shein, E. Zharkova, M. A. Kashchenko +11
The rapid development of infrared spectroscopy, observational astronomy, and scanning near-field microscopy has been enabled by the emergence of sensitive mid- and far-infrared pho…
High-mobility compensated semimetals, orbital magnetization, and umklapp scattering in bilayer graphene moire superlattices
A. L. Shilov, M. A. Kashchenko, P. A. Pantaleón +10
Twist-controlled moire superlattices (MS) have emerged as a versatile platform in which to realize artificial systems with complex electronic spectra. Bernal-stacked bilayer graphe…
Localization transition in non-Hermitian systems depending on reciprocity and hopping asymmetry
Daniil Kochergin, Vasilii Tiselko, Arsenii Onuchin
We studied the single-particle Anderson localization problem for non-Hermitian systems on directed graphs. Random regular graph and various undirected standard random graph models…
Robust extended states in Anderson model on partially disordered random regular graphs
Daniil Kochergin, Ivan M. Khaymovich, Olga Valba +1
In this work we analytically explain the origin of the mobility edge in the partially disordered random regular graphs of degree d, i.e., with a fraction of the sites being dis…
Anatomy of the fragmented Hilbert space: eigenvalue tunneling, quantum scars and localization in the perturbed random regular graph
Daniil Kochergin, Ivan M. Khaymovich, Olga Valba +1
We consider the properties of the random regular graph with node degree perturbed by chemical potentials for a number of short -cycles. We analyze both numerically and…
Generalized Devil's staircase and RG flows
Ana Flack, Alexander Gorsky, Sergei Nechaev
We discuss a two-parameter renormalization group (RG) flow when parameters are organized in a single complex variable, , with modular properties. Throughout the work we consider…
Failure of neuron network coherence induced by SARS-CoV-2-infected astrocytes
Sergey V. Stasenko, Alexander E. Hramov, Victor B. Kazantsev
Coherent activations of brain neuron networks underlay many physiological functions associated with various behavioral states. These synchronous fluctuations in the electrical acti…
Communities in C.elegans connectome through the prism of non-backtracking walks
Arsenii Onuchin, Alina Chernizova, Mikhail Lebedev +1
The fundamental relationship between the mesoscopic structure of neuronal circuits and organismic functions they subserve is one of the major challenges in contemporary neuroscienc…
