Stable and unstable helices: Soap films in cylindrical tubes
Brian Seguin, Eliot Fried
Cox & Jones recently devised and studied an interesting variant of the classical Plateau problem, a variant in which a helical soap film is confined to a cylindrical tube with circ…
Tunneling, self-trapping and manipulation of higher modes of a BEC in a double well
J. Gillet, M. A. Garcia-March, Th. Busch +1
We consider an atomic Bose-Einstein condensate trapped in a symmetric one-dimensional double well potential in the four-mode approximation and show that the semiclassical dynamics…
Non-integer optical modes in a Möbius-ring resonator
S. L. Li, L. B. Ma, V. M. Fomin +3
In-plane polarized light experiences a non-trivial topological evolution as it propagates resonantly in a Möbius ring resonator. The resultant geometric phase varies continuously w…
Pre-yield non-affine fluctuations and a hidden critical point in strained crystals
Tamoghna Das, Saswati Ganguly, Surajit Sengupta +1
A crystalline solid exhibits thermally induced localised {\em non-affine} droplets in the absence of external stress. Here we show that upon an imposed shear, the size of these dro…
Quantifying randomness in protein-protein interaction networks of different species: A random matrix approach
Ankit Agrawal, Camellia Sarkar, Sanjiv K. Dwivedi +2
We analyze protein-protein interaction networks for six different species under the framework of random matrix theory. Nearest neighbor spacing distribution of the eigenvalues of a…
Interaction of laser-cooled Rb atoms with higher order modes of an optical nanofiber
Ravi Kumar, Vandna Gokhroo, Aili Maimaiti +4
Optical nanofibres are used to confine light to subwavelength regions and are very promising tools for the development of optical fibre-based quantum networks using cold, neutral a…
Nanostructured optical nanofibres for atom trapping
Mark Daly, Viet Giang Truong, Ciarán Phelan +2
We propose an optical dipole trap for cold neutral atoms based on the electric field produced from the evanescent fields in a hollow rectangular slot cut through an optical nanofib…
Living on the edge : ground-state selection in quantum spin-ice pyrochlores
Han Yan, Owen Benton, Ludovic D. C. Jaubert +1
The search for new quantum phases, especially in frustrated magnets, is central to modern condensed matter physics. One of the most promising places to look is in rare-earth pyroch…
Particle-based simulations of self-motile suspensions
Denis F. Hinz, Alexander Panchenko, Tae-Yeon Kim +1
A simple model for simulating flows of active suspensions is investigated. The approach is based on dissipative particle dynamics. While the model is potentially applicable to a wi…
Two-component Dirac-like Hamiltonian for generating quantum walk on one-, two- and three-dimensional lattices
C. M. Chandrashekar
From the unitary operator used for implementing two-state discrete-time quantum walk on one-, two- and three- dimensional lattice we obtain a two-component Dirac-like Hamiltonian.…
Quantum limit for nuclear spin polarization in semiconductor quantum dots
Julia Hildmann, Eleftheria Kavousanaki, Guido Burkard +1
A recent experiment [E. A. Chekhovich et al., Phys. Rev. Lett. 104, 066804 (2010)] has demonstrated that high nuclear spin polarization can be achieved in self-assembled quantum do…
Wave turbulence in the two-layer ocean model
Katie L Harper, Sergey V Nazarenko, Sergey B Medvedev +1
This paper looks at the two-layer ocean model from a wave turbulence perspective. A symmetric form of the two-layer kinetic equation for Rossby waves is derived using canonical var…
Two-Qubit Gate Operation on Selected Nearest-Neighbor Neutral Atom Qubits
Elham Hosseini Lapasar, Kenichi Kasamatsu, Sile Nic Chormaic +4
We have previously discussed the design of a neutral atom quantum computer with an on-demand interaction [E. Hosseini Lapasar, et al., J. Phys. Soc. Jpn. 80, 114003 (2011)]. In thi…
Statistics of the work distribution for a quenched Fermi gas
A. Sindona, N. Lo Gullo, J. Goold +1
The local quench of a Fermi gas, giving rise to the Fermi edge singularity and the Anderson orthogonality catastrophe, is a rare example of an analytically tractable out of equilib…
Stability and Dynamics of Cross Solitons in Harmonically Confined Bose-Einstein Condensates
T. Morgan, Th. Busch
We examine the stability and dynamics of a family of crossed dark solitons in a harmonically confined Bose-Einstein condensate in two dimensions. Working in a regime where the fund…
Quantum state transfer in the presence of non homogeneous external potentials
Gian Luca Giorgi, Thomas Busch
Heisenberg-type spin models in the limit of a low number of excitations are useful tools to study basic mechanisms in strongly correlated and magnetic systems. Many of these mechan…
Coherent transport by adiabatic passage on atom chips
T. Morgan, L. J. O'Riordan, N. Crowley +2
Adiabatic techniques offer some of the most promising tools to achieve high-fidelity control of the centre-of-mass degree of freedom of single atoms. As their main requirement is t…
Criticality, factorization and long-range correlations in the anisotropic XY-model
Steve Campbell, Jonathan Richens, Nicola Lo Gullo +1
We study the long-range quantum correlations in the anisotropic XY-model. By first examining the thermodynamic limit we show that employing the quantum discord as a figure of merit…
Self-avoiding quantum walks: realisations in subspaces and limit theorems
Takuya Machida, C. M. Chandrashekar, Norio Konno +1
While completely self-avoiding quantum walks have the distinct property of leading to a trivial unidirectional transport of a quantum state, an interesting and non-trivial dynamics…
Shaping the evanescent field of optical nanofibers for cold atom trapping
C. F. Phelan, T. Hennessy, Th. Busch
We investigate trapping geometries for cold, neutral atoms that can be created in the evanescent field of a tapered optical fibre by combining the fundamental mode with one of the…

Rashi Sachdeva, Sankalpa Ghosh
Within mean field Gross-Pitaevskii framework, ultra cold atomic condensates with long range interaction is predicted to have a supersolid like ground state beyond a critical intera…
Sharp crossover from composite fermionization to phase separation in mesoscopic mixtures of ultracold bosons
M. A. Garcia-March, B. Julia-Diaz, G. E. Astrakharchik +3
We show that a two-component mixture of a few repulsively interacting ultracold atoms in a one-dimensional trap possesses very different quantum regimes and that the crossover betw…
New Spin Squeezing and Other Entanglement Tests for Two Mode Systems of Identical Bosons
Bryan Dalton. Libby Heaney, John Goold, Barry Garraway +1
For any quantum state representing a physical system of identical particles, the density operator must satisfy the symmetrisation principle (SP) and for massive particles also conf…
