• #### Looking Back ﻿

(Plenum Publishing Corporation, 2003)
Some of the organizers of this workshop advised me to write an autobiographical essay for this issue of the journal. First, I was not excited about this idea. I did not think that any details of my personal biography would ...
• #### Luminescence and spectroscopy ﻿

(Elsevier BV, 2002)
The connection between luminescence and different chapters of spectroscopy is discussed. Modern theoretical concepts and experimental techniques wiped away the boundaries that traditionally existed between them. Nevertheless, ...
• #### Mechanism of half-frequency electric dipole spin resonance in double quantum dots: Effect of nonlinear charge dynamics inside the singlet manifold ﻿

(American Physical Society (APS), 2011)
Near a neutrality point separating two different singlet charged states of a double quantum dot, charge dynamics inside a 2 × 2 singlet manifold can be described by a 1/2 pseudospin. In this region, charge dynamics is ...
• #### A New Mechanism of Electric Dipole Spin Resonance: Hyperfine Coupling in Quantum Dots ﻿

(Institute of Physics, 2009)
A recently discovered mechanism of electric dipole spin resonance, mediated by the hyperfine interaction, is investigated experimentally and theoretically. The effect is studied using a spin-selective transition in a GaAs ...
• #### Nuclear dynamics during Landau-Zener singlet-triplet transitions in double quantum dots ﻿

(American Physical Society (APS), 2011)
We consider nuclear-spin dynamics in a two-electron double dot system near the intersection of the electron spin singlet S and the lower energy component T+ of the spin triplet. The electron spin interacts with nuclear ...
• #### Orbital Mechanisms of Electron-Spin Manipulation by an Electric Field ﻿

(American Physical Society (APS), 2003)
A theory of spin manipulation of quasi-two-dimensional (2D) electrons by a time-dependent gate voltage applied to a quantum well is developed. The Dresselhaus and Rashba spin-orbit coupling mechanisms are shown to be rather ...
• #### Orthogonal localized wave functions of an electron in a magnetic field ﻿

(American Physical Society (APS), 1997)
We prove the existence of a set of two-scale magnetic Wannier orbitals w_{m,n}(r) on the infinite plane. The quantum numbers of these states are the positions {m,n} of their centers which form a von Neumann lattice. Function ...
• #### Paramagnetic Ion-Doped Nanocrystal as a Voltage-Controlled Spin Filter ﻿

(American Physical Society (APS), 2001)
A theory of spin injection from a ferromagnetic source into a semiconductor through a paramagnetic ion-doped nanocrystal is developed. Spin-polarized current from the source polarizes the ion; the polarized ion, in turn, ...

(Elsevier BV, 2015)
• #### Progress in exciton spectroscopy: personal perspective ﻿

(Elsevier BV, 2000)
In this Lecture, I display my personal perspective on the progress in physics of excitons during the last 50years. Preference is given to the areas of this extensive field which I participated. They include molecular ...
• #### Quantum nanostructures in strongly spin-orbit coupled two-dimensional systems ﻿

(American Physical Society (APS), 2012)
Recent progress in experimental studies of low-dimensional systems with strong spin-orbit coupling poses a question on the effect of this coupling on the energy spectrum of electrons in semiconductor nanostructures. It is ...
• #### Quantum-Dot-Based Resonant Exchange Qubit ﻿

(American Physical Society (APS), 2013)
We introduce a solid-state qubit in which exchange interactions among confined electrons provide both the static longitudinal field and the oscillatory transverse field, allowing rapid and full qubit control via rf ...
• #### Quenching of dynamic nuclear polarization by spin–orbit coupling in GaAs quantum dots ﻿

(Nature Pub. Group, 2015)
The central-spin problem is a widely studied model of quantum decoherence. Dynamic nuclear polarization occurs in central-spin systems when electronic angular momentum is transferred to nuclear spins and is exploited in ...
• #### Relaxation and Dephasing in a Two-Electron $^{13}C$ Nanotube Double Quantum Dot ﻿

(American Physical Society, 2009)
We use charge sensing of Pauli blockade (including spin and isospin) in a two-electron $^{13}C$ nanotube double quantum dot to measure relaxation and dephasing times. The relaxation time $T_1$ first decreases with a ...

• #### Restrictions on modeling spin injection by resistor networks ﻿

(IOP Publishing, 2008)
Because of the technical difficulties of solving spin transport equations in inhomogeneous systems, different resistor networks are widely applied for modeling spin transport. By comparing an analytical solution for spin ...
• #### Self trapping from degenerate bands (spin S = 1) and related phenomena ﻿

(MAIK Nauka/Interperiodica, 1984)
A theory of the self-trapping barrier in crystal with degenerate bands (spin S = 1) is developed for holes and Frenkel excitons. It is shown that band degeneracy leads to spontaneous symmetry breaking of the barrier, which ...
• #### Self-Consistent Measurement and State Tomography of an Exchange-Only Spin Qubit ﻿

(Nature Publishing Group, 2013)
Quantum-dot spin qubits characteristically use oscillating magnetic or electric fields, or quasi-static Zeeman field gradients, to realize full qubit control. For the case of three confined electrons, exchange interaction ...
