Travelling waves in an ensemble of excitable oscillators: the interplay of memristive coupling and noise
Using methods of numerical simulation, we demonstrate the constructive role of memristive coupling in the context of the travelling waves formation and robustness in an ensemble of excitable oscillators described by the FitzHugh-Nagumo neuron model. First, the revealed aspects of the memristive coupling action are shown on an example of the deterministic model where the memristive properties of the coupling elements provide for achieving travelling waves at lower coupling strength as compared t…

I am travelling from Turku to Stockholm on the night ship on the 30th. That is the night of the switch to daylight saving time. The arrival time is normally 06:30. If the ship would use normal speed, it would on this day then arrive at 07:30. But they use higher speed in the crossing and the planned arrival is at 06:50. My train leaves at 08:20. So no problem in catching the train. #Interrail

health/illness (mine)
Not very well last night & this morning. Yesterday evening slight nausea, overnight had a nightmare (where the house was on fire!), this morning headache & slight sore throat.
The most worrying bit is the timing - I was travelling on Monday & had a slight mask-fumble as I got onto the bus in a rush, so I know I breathed a little bit of unfiltered "bus air"! though windows were open & CO₂ was low. Also on trains well-masked.
Fingers crossed it's just something minor.

Travelling waves in a minimal go-or-grow model of cell invasion
We consider a minimal go-or-grow model of cell invasion, whereby cells can either proliferate, following logistic growth, or move, via linear diffusion, and phenotypic switching between these two states is density-dependent. Formal analysis in the fast switching regime shows that the total cell density in the two-population go-or-grow model can be described in terms of a single reaction-diffusion equation with density-dependent diffusion and proliferation. Using the connection to single-populat…

A 4-8 GHz Kinetic Inductance Travelling-Wave Parametric Amplifier Using Four-Wave Mixing with Near Quantum-Limit Noise Performance
Kinetic inductance traveling-wave parametric amplifiers (KI-TWPA) have a wide instantaneous bandwidth with near quantum-limited sensitivity and a relatively high dynamic range. Because of this, they are suitable readout devices for cryogenic detectors and superconducting qubits and have a variety of applications in quantum sensing. This work discusses the design, fabrication, and performance of a KI-TWPA based on four-wave mixing in a NbTiN microstrip transmission line. This device amplifies a …

Generalized paths and cycles in semicomplete multipartite digraphs
It is well-known and easy to show that even the following version of the directed travelling salesman problem is NP-complete: Given a strongly connected complete digraph $D=(V,A)$, a cost function $w: A\rightarrow \{0,1\}$ and a natural number $K$; decide whether $D$ has a directed Hamiltonian cycle of cost at most $K$. We study the following variant of this problem for $\{0,1\}$-weighted semicomplete digraphs where the set of arcs which have cost 1 form a collection of vertex-disjoint complete…

I've been thinking about doing a bigger live coding event in Sheffield but it's difficult to get funding to pay artist fees and expenses, and it's not really possible to cover them from ticket sales. In the old days people often weren't paid to play but this excludes people who can't afford it.. But it was much easier to make events happen. How do people feel about this these days, both organisers and people travelling to perform (and of course those who do both)?

Stability of asymptotic waves in the Fisher-Stefan equation
We establish spectral, linear, and nonlinear stability of the vanishing and slow-moving travelling waves that arise as time asymptotic solutions to the Fisher-Stefan equation. Nonlinear stability is in terms of the limiting equations that the asymptotic waves satisfy.

Ising model with non-reciprocal interactions
Effective interactions that violate Newton's third law of action-reaction symmetry are common in systems where interactions are mediated by a non-equilibrium environment. Extensive Monte Carlo simulations are carried out on a two-dimensional Ising model, where the interactions are modified non-reciprocally. We demonstrate that the critical temperature decreases as the non-reciprocity increases and this decrease depends only on the magnitude of non-reciprocity. Further, travelling spin waves due…

Intermediate Charge-Breaking Phases and Symmetry Non-Restoration in the 2-Higgs-Doublet Model
The Higgs potentials of extended Higgs sectors exhibit a complex and interesting vacuum structure. When travelling back in time, i.e. going to higher temperatures, the structure may change and exhibit interesting phase patterns and sequences of phases related to the respective minima of the potential. The investigation of the vacuum structure can give us indirect insights in beyond-Standard-Model physics and the evolution of the Universe. In this paper, we investigate the possibility of an inte…

Spin wave vortex as topological probe of magnetic texture
A vortex, a circulating flow around a void, is one of the basic topological phenomena in nature. Here we show that vortices generally emerge in spin wave travelling upon topologically nontrivial magnetic texture, due to the transverse precession of spin wave about the background magnetization. The winding number of each spin wave vortex is equivalent to sign of the local topological density of magnetic texture at the vortex core, and all winding numbers add up as twice the topological number of…

Stability of partially congested travelling wave solutions for the extended Aw-Rascle system
We prove the non-linear stability of a class of travelling-wave solutions to the extended Aw-Rascle system with a singular offset function, which is formally equivalent to the compressible pressureless Navier-Stokes system with a singular viscosity. These solutions encode the effect of congestion by connecting a congested left state to an uncongested right state, and may also be viewed as approximations of solutions to the 'hard-congestion model'. By using carefully weighted energy estimates we…

Gottesman-Kitaev-Preskill encoding in continuous modal variables of single photons
GKP states, introduced by Gottesman, Kitaev, and Preskill, are continuous variable logical qubits that can be corrected for errors caused by phase space displacements. Their experimental realization is challenging, in particular using propagating fields, where quantum information is encoded in the quadratures of the electromagnetic field. However, travelling photons are essential in many applications of GKP codes involving the long-distance transmission of quantum information. We introduce a ne…

Transformation and amplification of light in optical waveguides and resonators modulated by a low frequency traveling wave
We investigate the transformation and amplification of a light wave with phase velocity $v$ and frequency $ω$ propagating through an optical waveguide and a racetrack resonator parametrically modulated by a travelling wave with phase velocity $v_p$ and frequency $ω_p \ll ω$. We consider the propagation within a small bandwidth $Δω\ll ω$ where the waveguide is assumed to be dispersionless and low loss. Close to the luminal condition, $v_p=v$, the bandwidth of the output frequency comb spec…

We studied lossless discrete transmission lines constructed from ideal linear inductors and nonlinear capacitors. The travelling waves with finite support in such systems are the kinks and the solitons, which speeds and profiles were calculated. We also studied lossy transmission lines. The travelling waves with finite support in such systems are the dissipative kinks and the shocks, which speeds and profiles were also calculated.

The qubit scalability imposes a paramount challenge in the field of quantum computing. Photonic interconnects between distinct quantum computing modules provide a solution to deal with this issue. The fundamental part of this approach is entanglement distribution via travelling photons emitted by matter qubits. However, randomness of the spontaneous emission in the matter qubits limits both the entanglement fidelity and the generation rate. In this paper, by numerical and analytical methods, we…

Radio-frequency particle accelerators are engines of discovery, powering high-energy physics and photon science, but are also large and expensive due to their limited accelerating fields. Plasma-wakefield accelerators (PWFAs) provide orders-of-magnitude stronger fields in the charge-density wave behind a particle bunch travelling in a plasma, promising particle accelerators of greatly reduced size and cost. However, PWFAs can easily degrade the beam quality of the bunches they accelerate. Emitt…
