Bulk spin conductivity of three-dimensional topological insulator
R. S. Akzyanov
We study the spin conductivity of the bulk states of three-dimensional topological insulators within Kubo formalism. Spin Hall effect is the generation of the spin current that is…
Nonexponential photoluminescence dynamics in an inhomogeneous ensemble of excitons in WSe monolayers
M. A. Akmaev, M. V. Kochiev, A. I. Duleba +3
The spectral and spatiotemporal dynamics of photoluminescence in monolayers of transition metal dichalcogenide WSe obtained by mechanical exfoliation on a Si/SiO substrate…
Superconductor-insulator transition in capacitively coupled superconducting nanowires
Alex Latyshev, Andrew G. Semenov, Andrei D. Zaikin
We investigate superconductor-insulator quantum phase transitions in ultrathin capacitively coupled superconducting nanowires with proliferating quantum phase slips. We derive a se…
Coulomb blockade in field electron emission from carbon nanotubes
Victor I. Kleshch, Vitali Porshyn, Pavel Serbun +7
We report the observation of Coulomb blockade in field electron emission (FE) from single-wall carbon nanotubes (SWCNTs), which is manifested as pronounced steps in the FE current-…
Majorana entropy revival via tunneling phases
Sergey Smirnov
Measuring the Majorana entropy may uniquely reveal whether an initial equilibrium state of a nanoscale device is of Majorana nature and subsequent oper…
Surface and volume photoemission from metal nano-particles with electron mass discontinuity
I. E. Protsenko, A. V. Uskov
Quantum efficiencies of surface (SPE) and volume (VPE) photo-emissions from metal nanoparticles are calculated by quantum mechanical perturbation theory and compared with each othe…
Bulk cyclotron resonance in the topological insulator Bi2Te3
Dmytro L. Kamenskyi, Artem V. Pronin, Hadj M. Benia +3
We investigated magneto-optical response of undoped Bi2Te3 films in the terahertz frequency range (0.3 - 5.1 THz, 10 - 170 cm-1) in magnetic fields up to 10 T. The optical transmis…
Resonant spin amplification meets electron spin resonance in -GaAs
V. V. Belykh, D. N. Sob'yanin, A. R. Korotneva
Periodic excitation of electron spin polarization by consecutive laser pulses in phase with Larmor spin precession about a magnetic field results in resonant spin amplification (RS…
Time-dependent Andreev reflection
Dmitri V. Averin, Gongqi Wang, Andrey S. Vasenko
We extend the basic theory of Andreev reflection (AR) in a normal metal/superconductor junction to the situation with an arbitrary time-dependent bias voltage across the jun…
Anomalous magnetic suppression of spin relaxation in a two-dimensional electron gas in a GaAs/AlGaAs quantum well
V. V. Belykh, M. V. Kochiev, D. N. Sob'yanin +2
We study the spin dynamics in a high-mobility two-dimensional electron gas confined in a GaAs/AlGaAs quantum well. An unusual magnetic field dependence of the spin relaxation is fo…
Simple mechanism that breaks the Hall effect linearity at low temperatures
A. Yu. Kuntsevich, A. V. Shupletsov, A. L. Rakhmanov
Hall resistance is commonly suggested to be linear-in-magnetic-field , provided the field is small. We argue here that at low temperatures this linearity is br…
Electron-Hole Liquid in Monolayer Transition Metal Dichalcogenide Heterostructures
P. L. Pekh, P. V. Ratnikov, A. P. Silin
Monolayer films of transition metal dichalcogenides (in particular, MoS2, MoSe2, WS2, and WSe2) can be considered as ideal systems for the studies of high-temperature electron-hole…
Effect of disorder on the transverse magnetoresistance of Weyl semimetals
Ya. I. Rodionov, K. I. Kugel, B. A. Aronzon +1
We study the effect of random potential created by different types of impurities on the transverse magnetoresistance of Weyl semimetals. It is shown that the magnetic field and tem…
Optical detection of electron spin dynamics driven by fast variations of a magnetic field: a simple method to measure , , and in semiconductors
V. V. Belykh, D. R. Yakovlev, M. Bayer
We develop a simple method for measuring the electron spin relaxation times , and in semiconductors and demonstrate its exemplary application to -type GaAs. U…
Dual Majorana universality in thermally induced nonequilibrium
Sergey Smirnov
We demonstrate that nonequilibrium nanoscopic systems with Majorana zero modes admit special kind of universality which cannot be classified as of strictly transport or strictly th…
Temporal and spectral fingerprints of ultrafast all-coherent spin switching
S. Schlauderer, C. Lange, S. Baierl +7
Future information technology demands ultimately fast, low-loss quantum control. Intense light fields have facilitated important milestones, such as inducing novel states of matter…
