Strain-induced enhancement of electric quadrupole splitting in resistively detected nuclear magnetic resonance spectrum in quantum Hall systems
Minoru Kawamura, Tatsuya Yamashita, Hiroyuki Takahashi +4
We show electrical coherent manipulation of quadrupole-split nuclear spin states in a GaAs/AlGaAs heterostructure on the basis of the breakdown of quantum Hall effect. The electric…
Quantum emulation of a spin system with topologically protected ground states using superconducting quantum circuits
J. Q. You, Xiao-Feng Shi, Xuedong Hu +1
Using superconducting quantum circuit elements, we propose an approach to experimentally construct a Kitaev lattice, which is an anisotropic spin model on a honeycomb lattice with…
Tunable Electromagnetically Induced Transparency and Absorption with Dressed Superconducting Qubits
Hou Ian, Yu-xi Liu, Franco Nori
Electromagnetically induced transparency and absorption (EIT and EIA) are usually demonstrated by three-level atomic or atom-like systems. In contrast to the usual case, we theoret…
Film-thickness dependence of 10 GHz Nb coplanar-waveguide resonators
Kunihiro Inomata, Tsuyoshi Yamamoto, Michio Watanabe +2
We have studied Nb lambda/2 coplanar-waveguide (CPW) resonators whose resonant frequencies are 10-11 GHz. The resonators have different film thicknesses, t=0.05, 0.1, 0.2, and 0.3…
Power-dependent internal loss in Josephson bifurcation amplifiers
Michio Watanabe, Kunihiro Inomata, Tsuyoshi Yamamoto +1
We have studied nonlinear superconducting resonators: lambda/2 coplanar-waveguide (CPW) resonators with Josephson junctions (JJs) placed in the middle and lambda/4 CPW resonators t…
Perovskite Manganites Hosting Versatile Multiferroic Phases with Symmetric and Antisymmetric Exchange Strictions
S. Ishiwata, Y. Kaneko, Y. Tokunaga +3
Complete magnetoelectric (ME) phase diagrams of orthorhombic MnO with and without magnetic moments on the ions have been established. Three kinds of multiferroic groun…
Unconventional superconductivity on a topological insulator
Jacob Linder, Yukio Tanaka, Takehito Yokoyama +2
We study proximity-induced superconductivity on the surface of a topological insulator (TI), focusing on unconventional pairing. We find that the excitation spectrum becomes gaples…
Landau-Zener-Stuckelberg interferometry
S. N. Shevchenko, S. Ashhab, Franco Nori
A transition between energy levels at an avoided crossing is known as a Landau-Zener transition. When a two-level system (TLS) is subject to periodic driving with sufficiently larg…
Anisotropic order parameter in Li-intercalated layered superconductor LiZrNCl
M. Hiraishi, R. Kadono, M. Miyazaki +6
In this study, it is shown that in a layered nitride superconductor, i.e., LixZrNCl (0.07<=x<=0.21), the superconducting order parameter is highly anisotropic in a sample with x=0.…
Qubit-induced phonon blockade as a signature of quantum behavior in nanomechanical resonators
Yu-xi Liu, Adam Miranowicz, Y. B. Gao +3
The observation of quantized nanomechanical oscillations by detecting femtometer-scale displacements is a significant challenge for experimentalists. We propose that phonon blockad…
Electronic self-organization in the single-layer manganite
F. Ye, Songxue Chi, J. A. Fernandez-Baca +7
We use neutron scattering to investigate the doping evolution of the magnetic correlations in the single-layer manganite , away from the …
Controlling the transport of single photons by tuning the frequency of either one or two cavities in an array of coupled cavities
Jie-Qiao Liao, Z. R. Gong, Lan Zhou +3
We theoretically study how to control transport, bound states, and resonant states of a single photon in a one-dimensional coupled-cavity array. We find that the transport of a sin…

We examine the Bose-Einstein condensation of exciton-polaritons in a semiconductor microcavity via an electrical current. We propose that by embedding a quantum dot p-i-n junction…
Layered superconductors as negative-refractive-index metamaterials
A. L. Rakhmanov, V. A. Yampol'skii, J. A. Fan +2
We analyze the use of layered superconductors as anisotropic metamaterials. Layered superconductors can have a negative refraction index in a wide frequency range for arbitrary inc…
