The Magnetoelastic Distortion of Multiferroic BiFeO in the Canted Antiferromagnetic State
Toomas Rõõm, Johan Viirok, Laur Peedu +17
Using THz spectroscopy, we show that the spin-wave spectrum of multiferroic BiFeO in its high-field canted antiferromagnetic state is well described by a spin model that violat…
Electric current noise in mesoscopic organic semiconductors
D. S. Smirnov, A. V. Shumilin
We demonstrate that nuclear spin fluctuations lead to the electric current noise in the mesoscopic samples of organic semiconductors showing the pronounced magnetoresistance in wea…
Nuclear spin dynamics, noise, squeezing and entanglement in box model
A. V. Shumilin, D. S. Smirnov
We obtain a compact analytical solution for the nonlinear equation for the nuclear spin dynamics in the central spin box model in the limit of many nuclear spins. The total nuclear…
Quantum Zeno effect under continuous spin noise measurement in a quantum dot-micropillar cavity
N. V. Leppenen, L. Lanco, D. S. Smirnov
We theoretically describe the quantum Zeno effect in a spin-photon interface represented by a charged quantum dot in a micropillar cavity. The electron spin in this system entangle…
Symmetry-resolved two-magnon excitations in a strong spin-orbit-coupled bilayer antiferromagnet
Siwen Li, Elizabeth Drueke, Zach Porter +7
We used a combination of polarized Raman spectroscopy and spin wave calculations to study magnetic excitations in the strong spin-orbit-coupled (SOC) bilayer perovskite antiferroma…
Exciton energy oscillations induced by quantum beats
A. V. Trifonov, A. S. Kurdyubov, I. Ya. Gerlovin +5
In this paper, we experimentally demonstrate an oscillating energy shift of quantum-confined exciton levels in a semiconductor quantum well after excitation into a superposition of…
Optical Resonance Shift Spin Noise Spectroscopy
D. S. Smirnov, K. V. Kavokin
Quantum spin fluctuations provide a unique way to study spin dynamics without system perturbation. Here we put forward an optical resonance shift spin noise spectroscopy as a power…
