Quantum electrometry of non-volatile space charges in diamond
R. M. Goldblatt, N. Dontschuk, D. J. McCloskey +2
The microscopic electric environment surrounding a spin defect in a wide-bandgap semiconductor plays a determining role in the spin coherence and charge stability of a given qubit…
Roadmap to vortex nucleation below critical rotation frequency in a dipolar Bose-Einstein condensate
Soumyadeep Halder, Hari Sadhan Ghosh, Arpana Saboo +2
The formation of quantized vortices in a superfluid above a certain critical trap rotation frequency serves as a hallmark signature of superfluidity. Based on the beyond mean field…
3D-mapping and manipulation of photocurrent in an optoelectronic diamond device
A. A. Wood, D. J. McCloskey, N. Dontschuk +10
Characterising charge transport in a material is central to the understanding of its electrical properties, and can usually only be inferred from bulk measurements of derived quant…
Quench dynamics of edge states in a finite extended Su-Schrieffer-Heeger system
Anirban Ghosh, Andy M. Martin, Sonjoy Majumder
We examine the quench dynamics of an extended Su-Schrieffer-Heeger(SSH) model involving long-range hopping that can hold multiple topological phases. Using winding number diagrams…
Quench dynamics in the Jaynes-Cummings-Hubbard and Dicke models
Andrew R. Hogan, Andy M. Martin
Both the Jaynes-Cummings-Hubbard (JCH) and Dicke models can be thought of as idealised models of a quantum battery. In this paper we numerically investigate the charging properties…
DC Quantum Magnetometry Below the Ramsey Limit
Alexander A. Wood, Alastair Stacey, Andy M. Martin
We demonstrate quantum sensing of dc magnetic fields that exceeds the sensitivity of conventional -limited dc magnetometry by more than an order of magnitude. We used nit…
Quantum control of nuclear spin qubits in a rapidly rotating diamond
Alexander A. Wood, Russell M. Goldblatt, Robert E. Scholten +1
Nuclear spins in certain solids couple weakly to their environment, making them attractive candidates for quantum information processing and inertial sensing. When coupled to the s…
Reduced density matrix approach to ultracold few-fermion systems in one dimension
Mitchell J. Knight, Harry M. Quiney, Andy M. Martin
The variational determination of the two-fermion reduced density matrix is described for harmonically trapped, ultracold few-fermion systems in one dimension with equal spin popula…
Anisotropic electron-nuclear interactions in a rotating quantum spin bath
Alexander A. Wood, Russell M. Goldblatt, Russell P. Anderson +3
The interaction between a central qubit spin and a surrounding bath of spins is critical to spin-based solid state quantum sensing and quantum information processing. Spin-bath int…
Observation of a quantum phase from classical rotation of a single spin
Alexander A. Wood, Lloyd C. L. Hollenberg, Robert E. Scholten +1
The theory of angular momentum connects physical rotations and quantum spins together at a fundamental level. Physical rotation of a quantum system will therefore affect fundamenta…
Improved low-dimensional wave equations for cigar-shaped and disk-shaped dipolar Bose-Einstein condensates
Mitchell J. Knight, Thomas Bland, Nick G. Parker +1
Within the formalism of the Gross-Pitaevskii equation, we derive effective one- and two-dimensional equations for cigar- and pancake-shaped dipolar Bose-Einstein condensates with a…
Quantum measurement of a rapidly rotating spin qubit in diamond
Alexander A. Wood, Emmanuel Lilette, Yaakov Y. Fein +5
A controlled qubit in a rotating frame opens new opportunities to probe fundamental quantum physics, such as geometric phases in physically rotating frames, and can potentially enh…
