Continuous time crystal in an electron-nuclear spin system: stability and melting of periodic auto-oscillations
A. Greilich, N. E. Kopteva, A. N. Kamenskii +3
Crystals spontaneously break the continuous translation symmetry in space, despite the invariance of the underlying energy function. This has triggered suggestions of time crystals…
Unveiling the electron-nuclear spin dynamics in an n-doped InGaAs epilayer by spin noise spectroscopy
C. Rittmann, M. Yu. Petrov, A. N. Kamenskii +6
We discuss the implications of a small indium content (3%) in a GaAs epilayer on the electron- and nuclear-spin relaxation due to enhanced quadrupolar effects induced by the strain…
Extending the time of coherent optical response in ensemble of singly-charged InGaAs quantum dots
A. N. Kosarev, A. V. Trifonov, I. A. Yugova +10
The ability to extend the time scale of the coherent optical response from large ensembles of quantum emitters is highly appealing for applications in quantum information devices.…
Nonlinear Faraday effect and spin noise in rare-earth activated crystals
A. N. Kamenskii, G. G. Kozlov, E. I. Baibekov +4
The spin-noise spectroscopy (SNS) method implies high efficiency of conversion of the spin-system magnetization to the Faraday rotation angle. Generally, this efficiency cannot be…
Invariants in the paramagnetic resonance spectra of impurity crystals
A. N. Kamenskii, V. O. Kozlov, N. S. Kuznetsov +5
We show that in cubic crystals with anisotropic impurity centers the sum of squares of the magnetic resonance (EPR) frequencies is invariant with respect to the magnetic field dire…
Covalent 2D CrTe ferromagnet
Mengying Bian, Aleksandr N. Kamenskii, Mengjiao Han +16
To broaden the scope of van der Waals 2D magnets, we report the synthesis and magnetism of covalent 2D magnetic CrTe with a thickness down to one-unit-cell. The 2D CrTe…
Gigantic spin-noise gain enables magnetic resonance spectroscopy of impurity crystals
A. N. Kamenskii, A. Greilich, I. I. Ryzhov +3
Spin noise spectroscopy is a method of magnetic resonance widely used, nowadays, in atomic and semiconductor research. Classical objects of the EPR spectroscopy - dielectrics with…
Detection and amplification of spin noise using scattered laser light in a quantum-dot microcavity
A. N. Kamenskii, M. Yu. Petrov, G. G. Kozlov +7
Fundamental properties of the spin-noise signal formation in a quantum-dot microcavity are studied by measuring the angular characteristics of the scattered light intensity. A dist…
Stimulated spin noise in an activated crystal
M. M. Sharipova, A. N. Kamenskii, I. I. Ryzhov +5
In the spin noise spectroscopy, the magnetic susceptibility spectrum is known to be provided by the spin-system untouched by any external perturbation, or, better to say, disturbed…
Increased sensitivity of spin noise spectroscopy using homodyne detection in -doped GaAs
M. Yu. Petrov, A. N. Kamenskii, V. S. Zapasskii +2
We implement the homodyne detection scheme for an increase of the polarimetric sensitivity in spin noise spectroscopy. Controlling the laser intensity of the local oscillator, whic…
