Cubical Geometry in the Polygonalisation Complex
Mark C. Bell, Valentina Disarlo, Robert Tang
We introduce the polygonalisation complex of a surface, a cube complex whose vertices correspond to polygonalisations. This is a geometric model for the mapping class group and it…
Interplay of different environments in open quantum systems: Breakdown of the additive approximation
Giulio G. Giusteri, Filippo Recrosi, Gernot Schaller +1
We analyze an open quantum system under the influence of more than one environment: a dephasing bath and a probability-absorbing bath that represents a decay channel, as encountere…
Negative mass hydrodynamics in a Spin-Orbit--Coupled Bose-Einstein Condensate
M. A. Khamehchi, Khalid Hossain, M. E. Mossman +4
A negative effective mass can be realized in quantum systems by engineering the dispersion relation. A powerful method is provided by spin-orbit coupling, which is currently at the…
Odd-petal states and persistent flows in spin-orbit-coupled Bose-Einstein condensates
Angela C White, Yongping Zhang, Thomas Busch
We study the phase diagram of a Rashba spin-orbit-coupled Bose-Einstein condensate confined in a two-dimensional toroidal trap. In the immiscible regime we find an azimuthally peri…
Dynamics and energy spectra of aperiodic discrete-time quantum walks
C. V. Ambarish, N. Lo Gullo, Th. Busch +2
Deterministically aperiodic sequences are an intermediary between periodic sequences and completely random sequences. Materials which are translationally periodic have Bloch-like e…
Creating superfluid vortex rings in artificial magnetic fields
Rashi Sachdeva, Thomas Busch
Artificial gauge fields are versatile tools that allow to influence the dynamics of ultracold atoms in Bose-Einstein condensates. Here we discuss a method of artificial gauge field…
Importance and effectiveness of representing the shapes of Cosserat rods and framed curves as paths in the special Euclidean algebra
Giulio G. Giusteri, Eliot Fried
We discuss how the shape of a special Cosserat rod can be represented as a path in the special Euclidean algebra. By shape we mean all those geometric features that are invariant u…
Tracking chains revisited
Gunnar Wilken
The structure , introduced and first analyzed in Carlson and Wilken 2012 (APAL), is shown to be elementary recursive. Here, denot…
Spatial non-adiabatic passage using geometric phases
Albert Benseny, Anthony Kiely, Yongping Zhang +2
Quantum technologies based on adiabatic techniques can be highly effective, but often at the cost of being very slow. Here we introduce a set of experimentally realistic, non-adiab…
Spin-Orbit Dimers and Non-Collinear Phases in Cubic Double Perovskites
Judit Romhányi, Leon Balents, George Jackeli
We formulate and study a spin-orbital model for a family of cubic double perovskites with ions occupying a frustrated fcc sublattice. A variational approach and a complimenta…
Study of the Polarimetric Performance of a Si/CdTe Semiconductor Compton Camera for the Hitomi Satellite
Junichiro Katsuta, Ikumi Edahiro, Shin Watanabe +17
Gamma-ray polarization offers a unique probes into the geometry of the gamma-ray emission process in celestial objects. The Soft Gamma-ray Detector (SGD) onboard the X-ray observat…
Statistical test for detecting community structure in real-valued edge-weighted graphs
Tomoki Tokuda
We propose a novel method to test the existence of community structure of undirected real-valued edge-weighted graph. The method is based on Wigner semicircular law on the asymptot…
Flat bands and Dirac cones in breathing lattices
Karim Essafi, L. D. C. Jaubert, M. Udagawa
In breathing pyrochlores and kagomes, couplings between neighbouring tetrahedra and triangles are free to differ. Breathing lattices thus offer the possibility to explore a differe…
Random matrix analysis for gene interaction networks in cancer cells
Ayumi Kikkawa
Investigations of topological uniqueness of gene interaction networks in cancer cells are essential for understanding this disease. Based on the random matrix theory, we study the…
Symmetry and optical selection rules in graphene quantum dots
Rico Pohle, Eleftheria G. Kavousanaki, Keshav M. Dani +1
Graphene quantum dots (GQD's) have optical properties which are very different from those of an extended graphene sheet. In this Article we explore how the size, shape and edge--st…
Adaptive Graph-based Total Variation for Tomographic Reconstructions
Faisal Mahmood, Nauman Shahid, Ulf Skoglund +1
Sparsity exploiting image reconstruction (SER) methods have been extensively used with Total Variation (TV) regularization for tomographic reconstructions. Local TV methods fail to…
Proposal for detection of a single electron spin in a microwave resonator
P. Haikka, Y. Kubo, A. Bienfait +2
We propose a method for detecting the presence of a single spin in a crystal by coupling it to a high-quality factor superconducting planar resonator. By confining the microwave fi…
Spin Ice Thin Film: Surface Ordering, Partial Magnetic Wetting and Emergent Square Ice
L. D. C. Jaubert, T. Lin, T. S. Opel +2
Motivated by recent realizations of DyTiO and HoTiO spin ice thin films, and more generally by the physics of confined gauge fields, we study a…
Janus spectra in two-dimensional flows
Chien-Chia Liu, Rory T. Cerbus, Pinaki Chakraborty
In theory, large-scale atmospheric flows, soap-film flows and other two-dimensional flows may host two distinct types of turbulent energy spectra---in one, , the spectral expone…
Pure patterns of order 2
Gunnar Wilken
We provide mutual elementary recursive order isomorphisms between classical ordinal notations, based on Skolem hulling, and notations from pure elementary patterns of resemblance o…
Topological defect dynamics of vortex lattices in Bose--Einstein condensates
Lee James O'Riordan, Thomas Busch
Vortex lattices in rapidly rotating Bose--Einstein condensates are systems of topological excitations that arrange themselves into periodic patterns. Here we show how phase-imprint…
Curvature-induced stiffening of a fish fin
Khoi Nguyen, Ning Yu, Mahesh M. Bandi +2
How fish modulate their fin stiffness during locomotive manoeuvres remains unknown. We show that changing the fin's curvature modulates its stiffness. Modelling the fin as bendable…
Classical spin liquids in stacked triangular lattice Ising antiferromagnets
D. T. Liu, F. J. Burnell, L. D. C. Jaubert +1
We study Ising antiferromagnets that have nearest-neighbour interactions on multilayer triangular lattices with frustrated ( and ) stacking, and make comparisons with th…
Probing the out-of-equilibrium dynamics of two interacting atoms
Tim Keller, Thomás Fogarty
We study the out-of-equilibrium dynamics of two interacting atoms in a one-dimensional harmonic trap after a quench by a tightly pinned impurity atom. We make use of an approximate…
