Influence of nonequilibrium phonons on the spin dynamics of a single Cr atom

V. Tiwari, K. Makita, M. Arino, M. Morita, S. Kuroda, H. Boukari, and L. Besombes

Phys. Rev. B 101, 035305 (2020) - Published 30 January, 2020

Doping semiconductor quantum dots with transition elements can create an optical probe and can control spins of individual magnetic atoms. Such atoms that feature both spin and orbital degrees of freedom present a large spin-to-strain coupling and could be used in hybrid spin-mechanical devices. In particular, this is the case for chromium. Here, the authors show that the spin dynamics of an individual Cr atom embedded in a quantum dot is controlled by the interaction with nonequilibrium phonons. Excitation conditions are found where the Cr spin states can be optically initialized, conserved in the dark for a few microseconds, and read out by resonant fluorescence.

Universal finite-size scaling around tricriticality between topologically ordered, symmetry-protected topological, and trivial phases

Ke Wang and T. A. Sedrakyan

Phys. Rev. B 101, 035410 (2020) - Published 10 January, 2020

Quantum one-dimensional criticality with conformal invariance is known to be characterized by conformal field theory with the inherent central charge (c), and universal finite-size amplitudes. Here, the authors demonstrate that around a quantum criticality with c=½ and two Majorana boundary modes, the symmetry-breaking effect modifies the finite-size amplitudes from a universal constant to be a universal function of an emergent scale. This finding provides a new perspective to study the interplay of topology and quantum criticality.

Complete state tomography of a quantum dot spin qubit

Dan Cogan, Giora Peniakov, Zu-En Su, and David Gershoni

Phys. Rev. B 101, 035424 (2020) - Published 28 January, 2020

Semiconductor quantum dots are the preferred choice for interfacing anchored matter spin qubits and flying photonic qubits. They are particularly attractive for generating highly entangled hybrid spin-multiphoton entangled cluster and graph states. These highly entangled multiqubit states are required for measurement-based quantum communication and computing. Here, the authors develop a novel all-optical method for conducting full tomography of the confined electronic spin qubits. This method is essential for characterization and benchmarking these hybrid entangled spin-multiphoton cluster and graph states.

Inelastic light scattering by intrasubband spin-density excitations in GaAs-AlGaAs quantum wells with balanced Bychkov-Rashba and Dresselhaus spin-orbit interaction: Quantitative determination of the spin-orbit field

S. Gelfert, C. Frankerl, C. Reichl, D. Schuh, G. Salis, W. Wegscheider, D. Bougeard, T. Korn, and C. Schüller

Phys. Rev. B 101, 035427 (2020) - Published 29 January, 2020

The theoretically infinite spin lifetime makes the persistent spin helix (PSH) a very interesting candidate for spintronic research. Resonant Raman scattering on spin-density excitations permits insights into subtle many-body effects. Utilizing electronic Raman scattering, the authors present here a precise mapping of the huge spin-splitting anisotropy for two different configurations of the PSH. By modulating the effective spin-orbit fields with an external magnetic field, they reveal electron g factors for the two different configurations, probably influenced by collective effects in the intrasubband spin-density excitations.

Tuning single-electron charging and interactions between compressible Landau level islands in graphene

Daniel Walkup, Fereshte Ghahari, Christopher Gutiérrez, Kenji Watanabe, Takashi Taniguchi, Nikolai B. Zhitenev, and Joseph A. Stroscio

Phys. Rev. B 101, 035428 (2020) - Published 29 January, 2020

Interacting and tunable quantum dots (QDs) provide a powerful testbed in condensed matter physics and quantum information science. Here, the authors use a low-temperature scanning tunneling microscope to both create and directly image a new type of coupled QD system in graphene. In a strong magnetic field, the carriers condense into Landau levels (LLs), and the successive LLs form concentric spatially isolated Coulomb islands (compressible rings) within the confining electric potential well that behave as controllably coupled QDs.

Conductance and adhesion in an atomically precise Au-Au point contact

Lukas Gerhard and Wulf Wulfhekel

Phys. Rev. B 101, 035429 (2020) - Published 30 January, 2020

Electrical and mechanical properties of atom-sized metal contacts are of central importance for a number of fields in nanoscience. Here, the authors use an STM tip to contact an Au(111) surface. As both electrodes remain stable throughout 19,000 measurements, the atomic configuration of the point contact can be precisely controlled by positioning the tip with respect to the substrate. This allows to relate the atomic configuration of the electrodes to the conductance and the stiffness of the junction.

Universal finite-size scaling around tricriticality between topologically ordered, symmetry-protected topological, and trivial phases

Quantum one-dimensional criticality with conformal invariance is known to be characterized by conformal field theory with the inherent central charge (c), and universal finite-size amplitudes. Here, the authors demonstrate that around a quantum criticality with c=½ and two Majorana boundary modes, the symmetry-breaking effect modifies the finite-size amplitudes from a universal constant to be a universal function of an emergent scale. This finding provides a new perspective to study the interplay of topology and quantum criticality.

Semiconductor quantum dots are the preferred choice for interfacing anchored matter spin qubits and flying photonic qubits. They are particularly attractive for generating highly entangled hybrid spin-multiphoton entangled cluster and graph states. These highly entangled multiqubit states are required for measurement-based quantum communication and computing. Here, the authors develop a novel all-optical method for conducting full tomography of the confined electronic spin qubits. This method is essential for characterization and benchmarking these hybrid entangled spin-multiphoton cluster and graph states.

The theoretically infinite spin lifetime makes the persistent spin helix (PSH) a very interesting candidate for spintronic research. Resonant Raman scattering on spin-density excitations permits insights into subtle many-body effects. Utilizing electronic Raman scattering, the authors present here a precise mapping of the huge spin-splitting anisotropy for two different configurations of the PSH. By modulating the effective spin-orbit fields with an external magnetic field, they reveal electron g factors for the two different configurations, probably influenced by collective effects in the intrasubband spin-density excitations.

Tuning single-electron charging and interactions between compressible Landau level islands in graphene

Interacting and tunable quantum dots (QDs) provide a powerful testbed in condensed matter physics and quantum information science. Here, the authors use a low-temperature scanning tunneling microscope to both create and directly image a new type of coupled QD system in graphene. In a strong magnetic field, the carriers condense into Landau levels (LLs), and the successive LLs form concentric spatially isolated Coulomb islands (compressible rings) within the confining electric potential well that behave as controllably coupled QDs.

Conductance and adhesion in an atomically precise Au-Au point contact

Electrical and mechanical properties of atom-sized metal contacts are of central importance for a number of fields in nanoscience. Here, the authors use an STM tip to contact an Au(111) surface. As both electrodes remain stable throughout 19,000 measurements, the atomic configuration of the point contact can be precisely controlled by positioning the tip with respect to the substrate. This allows to relate the atomic configuration of the electrodes to the conductance and the stiffness of the junction.
