Shear viscosity of strongly interacting fermionic quantum fluids

Nandan Pakhira and Ross H. McKenzie

Phys. Rev. B 92, 125103 (2015) - Published 1 September, 2015

Shear viscosity for a fermionic fluid described by a single band Hubbard model is computed using dynamical mean field theory and found to violate the quantum limit.

Scattering particles in quantum spin chains

Laurens Vanderstraeten, Frank Verstraete, and Jutho Haegeman

Phys. Rev. B 92, 125136 (2015) - Published 18 September, 2015

Using a variational ansatz based on matrix product states, the authors present a methodology for determine the elementary excitations and their low energy scattering matrices of general quasi-one-dimensional spin systems. From these scattering matrices, the authors map the system unto an effective integrable model and then employ the thermodynamic Bethe ansatz so as to determine thermodynamic properties of the spin system. As a demonstration of the method, the authors apply it to a Heisenberg spin ladder.

Auxiliary master equation approach within matrix product states: Spectral properties of the nonequilibrium Anderson impurity model

Antonius Dorda, Martin Ganahl, Hans Gerd Evertz, Wolfgang von der Linden, and Enrico Arrigoni

Phys. Rev. B 92, 125145 (2015) - Published 24 September, 2015

The non-equilibrium Anderson impurity model is solved to an unprecedented accuracy to obtain its spectral properties in the steady state using a recently developed approach.

Low-loss electron energy loss spectroscopy: An atomic-resolution complement to optical spectroscopies and application to graphene

Myron D. Kapetanakis, Wu Zhou, Mark P. Oxley, Jaekwang Lee, Micah P. Prange, Stephen J. Pennycook, Juan Carlos Idrobo, and Sokrates T. Pantelides

Phys. Rev. B 92, 125147 (2015) - Published 25 September, 2015

This paper reports on successful application of electron energy loss spectroscopy (EELS) for probing low-energy electronic excitations at all values of momentum transfer with atomic-scale spatial resolution. In this regard EELS appears to be complementary to optical spectroscopy which probes only direct excitations with limited spatial resolution. The authors suggest that EELS can be used to study atomic-scale structural, electronic, magnetic and vibrational properties of systems having defects and impurities as well.

Fermi-level pinning through defects at GaAs/oxide interfaces: A density functional study

Davide Colleoni, Giacomo Miceli, and Alfredo Pasquarello

Phys. Rev. B 92, 125304 (2015) - Published 8 September, 2015

GaAs is the prototype material considered as a replacement for silicon in CMOS technology owing to its high electron mobility. However, the high density of interfacial defect states found at GaAs/oxide interfaces, which prevents the proper operation of GaAs-based devices through Fermi-level pinning, hinders the development of GaAs-based technology. In this thorough first-principles study of defects at the GaAs/Al2O3 interface, the authors deliver results that are very significant for the identification of the origins of Fermi-level pinning at these interfaces.

Exact CNOT gates with a single nonlocal rotation for quantum-dot qubits

Arijeet Pal, Emmanuel I. Rashba, and Bertrand I. Halperin

Phys. Rev. B 92, 125409 (2015) - Published 9 September, 2015

This theoretical study provides an exact implementation of the CNOT two-qubit gate operation between capacitively coupled exchange-only qubits defined by three electrons in triple quantum dots. The authors show that the CNOT gate can be implemented by tuning three parameters: the two single-qubit exchange splittings, and the duration of the pulse.

Two-dimensional Fourier transform spectroscopy of exciton-polaritons and their interactions

N. Takemura, S. Trebaol, M. D. Anderson, V. Kohnle, Y. Léger, D. Y. Oberli, M. T. Portella-Oberli, and B. Deveaud

Phys. Rev. B 92, 125415 (2015) - Published 11 September, 2015

Two-dimensional Fourier transform (2DFT) spectroscopy is a cutting-edge technique to investigate nonlinear many-body physics in semiconductor nanostructures. This paper reports an experimental and theoretical study of 2DFT on a high-quality GaAs-based semiconductor microcavity to gain an understanding of polariton self-interactions and polariton cross-interactions and their effects on the 2D spectra.

Hyperspherical theory of the quantum Hall effect: The role of exceptional degeneracy

K. M. Daily, R. E. Wooten, and Chris H. Greene

Phys. Rev. B 92, 125427 (2015) - Published 21 September, 2015

The fractional quantum Hall effect is traditionally viewed as a distinctive attribute of strongly-interacting electron systems. This paper develops an alternative picture which suggests that the low energy quantum states corresponding to an experimentally observable filling fractions can be identified by simply having an exceptionally high degeneracy in the noninteracting limit.

Polarization analysis of excitons in monolayer and bilayer transition-metal dichalcogenides

Hanan Dery and Yang Song

Phys. Rev. B 92, 125431 (2015) - Published 23 September, 2015

The authors theoretically study optical transitions in transition-metal dichalcogenides. In particular, they explain the difference between the excitonic properties of monolayer MoSe2 and WSe2. Excitons in WSe2 are thought to be bound to impurities. An alternative theory presented in this paper suggests that these excitons correspond to low-energy optical transitions. The authors also put forward an alternative explanation as to why the excitons in MoSe2 have vanishing polarization. They attribute this phenomenon to polaron-induced Rabi oscillations between dark and bright excitons.

Role of metastable charge states in a quantum-dot spin-qubit readout

J. D. Mason, S. A. Studenikin, A. Kam, Z. R. Wasilewski, A. S. Sachrajda, and J. B. Kycia

Phys. Rev. B 92, 125434 (2015) - Published 25 September, 2015

The authors present an experimental mechanism for converting the state of a spin qubit in a quantum dot device into different charge states. This mechanism depends on metastable charge states present when the device has very asymmetric couplings to the external leads. This approach is used to observe Landau-Zener-Stuckelberg oscillations of the (S-T+) qubit.

Phys. Rev. B 92, 125147 (2015) - Published 25 September, 2015

This paper reports on successful application of electron energy loss spectroscopy (EELS) for probing low-energy electronic excitations at all values of momentum transfer with atomic-scale spatial resolution. In this regard EELS appears to be complementary to optical spectroscopy which probes only direct excitations with limited spatial resolution. The authors suggest that EELS can be used to study atomic-scale structural, electronic, magnetic and vibrational properties of systems having defects and impurities as well.

Fermi-level pinning through defects at GaAs/oxide interfaces: A density functional study

Davide Colleoni, Giacomo Miceli, and Alfredo Pasquarello

Phys. Rev. B 92, 125304 (2015) - Published 8 September, 2015

GaAs is the prototype material considered as a replacement for silicon in CMOS technology owing to its high electron mobility. However, the high density of interfacial defect states found at GaAs/oxide interfaces, which prevents the proper operation of GaAs-based devices through Fermi-level pinning, hinders the development of GaAs-based technology. In this thorough first-principles study of defects at the GaAs/Al2O3 interface, the authors deliver results that are very significant for the identification of the origins of Fermi-level pinning at these interfaces.

This theoretical study provides an exact implementation of the CNOT two-qubit gate operation between capacitively coupled exchange-only qubits defined by three electrons in triple quantum dots. The authors show that the CNOT gate can be implemented by tuning three parameters: the two single-qubit exchange splittings, and the duration of the pulse.

The fractional quantum Hall effect is traditionally viewed as a distinctive attribute of strongly-interacting electron systems. This paper develops an alternative picture which suggests that the low energy quantum states corresponding to an experimentally observable filling fractions can be identified by simply having an exceptionally high degeneracy in the noninteracting limit.

Polarization analysis of excitons in monolayer and bilayer transition-metal dichalcogenides

Hanan Dery and Yang Song

Phys. Rev. B 92, 125431 (2015) - Published 23 September, 2015

The authors theoretically study optical transitions in transition-metal dichalcogenides. In particular, they explain the difference between the excitonic properties of monolayer MoSe2 and WSe2. Excitons in WSe2 are thought to be bound to impurities. An alternative theory presented in this paper suggests that these excitons correspond to low-energy optical transitions. The authors also put forward an alternative explanation as to why the excitons in MoSe2 have vanishing polarization. They attribute this phenomenon to polaron-induced Rabi oscillations between dark and bright excitons.

The authors present an experimental mechanism for converting the state of a spin qubit in a quantum dot device into different charge states. This mechanism depends on metastable charge states present when the device has very asymmetric couplings to the external leads. This approach is used to observe Landau-Zener-Stuckelberg oscillations of the (S-T+) qubit.
