Understanding the role of ions and water molecules in the NaCl dissolution process
Jiří Klimeš, David R. Bowler, Angelos Michaelides
The dissolution of NaCl in water is one of the most common everyday processes, yet it remains poorly understood at the molecular level. Here we report the results of an extensive d…
Microwave manipulation of electrically injected spin polarized electrons in silicon
C. C. Lo, J. Li, I. Appelbaum +1
We demonstrate microwave manipulation of the spin states of electrically injected spin-polarized electrons in silicon. Although the silicon channel is bounded by ferromagnetic meta…
Ab initio simulations of hydrogen-bonded ferroelectrics: collective tunneling and the origin of geometrical isotope effects
K. T. Wikfeldt, A. Michaelides
Ab initio simulations that account for nuclear quantum effects have been used to examine the order-disorder transition in squaric acid, a prototypical H-bonded antiferroelectric cr…
Orbital occupancies and the putative jeff = 1/2 groundstate in Ba2IrO4: a combined oxygen K edge XAS and RIXS study
M. Moretti Sala, M. Rossi, S. Boseggia +9
The nature of the electronic groundstate of Ba2IrO4 has been addressed using soft X-ray absorption and inelastic scattering techniques in the vicinity of the oxygen K edge. From th…
Quantification and Control of non-Markovian Evolution in Finite Quantum Systems via Feedback
Nicholas Chancellor, Christoph Petri, Lorenzo Campos Venuti +2
We consider the unitary time evolution of continuous quantum mechanical systems confined to a cavity in contact with a finite bath of variable size. Measures for Markovianity for s…
Transport Spectroscopy of a Graphene Quantum Dot Fabricated by Atomic Force Microscope Nanolithography
R. K. Puddy, C. J. Chua, M. R. Buitelaar
We report low-temperature transport spectroscopy of a graphene quantum dot fabricated by atomic force microscope nanolithography. The excellent spatial resolution of the atomic for…
Circularly Polarised X-ray Scattering Investigation of Spin-Lattice Coupling in TbMnO in Crossed Electric and Magnetic Fields
H. C. Walker, F. Fabrizi, L. Paolasini +4
We present a study of the magnetic and crystallographic structure of TbMnO in the presence of crossed electric and magnetic fields using circularly polarised X-ray non-resonant…
Quantum Exact Non-Abelian Vortices in Non-relativistic Theories
Muneto Nitta, Shun Uchino, Walter Vinci
Non-Abelian vortices arise when a non-Abelian global symmetry is exact in the ground state but spontaneously broken in the vicinity of their cores. In this case, there appear (non-…
Universal equation of state and pseudogap in the two-dimensional Fermi gas
Marianne Bauer, Meera M. Parish, Tilman Enss
We determine the thermodynamic properties and the spectral function for a homogeneous two-dimensional Fermi gas in the normal state using the Luttinger-Ward, or self-consistent T-m…
Fermi liquid breakdown and evidence for superconductivity in YFeGe
Y. Zou, Z. Feng, P. W. Logg +3
In the d-electron system YFeGe, an unusually high and temperature dependent Sommerfeld ratio of the specific heat capacity and an anomal…
Nonlinear Surface-Plasmon Whispering-Gallery Modes in Metallic Nanowire Cavities
Claudiu G. Biris, Nicolae C. Panoiu
We demonstrate that the surface second-harmonic generation can lead to the formation of nonlinear plasmonic whispering-gallery modes (WGMs) in microcavities made of metallic nanowi…
Large in-plane deformation of RuO6 octahedron and ferromagnetism of bulk SrRuO3
Sanghyun Lee, J. R. Zhang, S. Torii +6
SrRuO3 is a ferromagnetic metal with several unusual physical properties such as zero thermal expansion below Tc, so-called Invar behavior. Another anomalous feature is that the a-…
Non-Abelian Vortices with an Aharonov-Bohm Effect
Jarah Evslin, Kenichi Konishi, Muneto Nitta +2
The interplay of gauge dynamics and flavor symmetries often leads to remarkably subtle phenomena in the presence of soliton configurations. Non-Abelian vortices -- vortex solutions…
Quantum correlations in the 1-D driven dissipative transverse field XY model
Chaitanya Joshi, Felix Nissen, Jonathan Keeling
We study the non-equilibrium steady state (NESS) of a driven dissipative one-dimensional system near a critical point, and explore how the quantum correlations compare to the known…
Temperature and Field Dependence of Magnetic Domains in LaSrMnO
B. Bryant, Y. Moritomo, Y. Tokura +1
Colossal magnetoresistance and field-induced ferromagnetism are well documented in manganite compounds. Since domain wall resistance contributes to magnetoresistance, data on the t…
Slaving of the magnetic moment canting to the correlated oxygen rotation in Sr2IrO4 revealed by X-ray resonant scattering
S. Boseggia, H. C. Walker, J. Vale +6
Sr2IrO4 is a prototype of the class of Mott insulators in the strong spin-orbit interaction (SOI) limit described by a ground state. In Sr2IrO4, the strong S…
Pair Correlations in the Two-Dimensional Fermi Gas
V. Ngampruetikorn, J. Levinsen, Meera M. Parish
We consider the two-dimensional Fermi gas at finite temperature with attractive short-range interactions. Using the virial expansion, which provides a controlled approach at high t…
Spin ladders and quantum simulators for Luttinger liquids
S. Ward, P. Bouillot, H. Ryll +5
Magnetic insulators have proven to be usable as quantum simulators for itinerant interacting quantum systems. In particular the compound (CHN)CuBr (short (…
