Spectral quantities in thermal QCD: a progress report from the FASTSUM collaboration

Gert Aarts, Chris Allton, Jonas Glesaaen +8

In order to study spectral quantities in thermal QCD, the FASTSUM collaboration employs anisotropic lattice simulations with N_f=2+1 flavours of Wilson fermions. Here we discuss ou…

Gauge coupling beta functions to four-loop order in the Standard Model

Joshua Davies, Florian Herren, Colin Poole +2

We compute the beta functions of the three Standard Model gauge couplings to four-loop order in the modified minimal subtraction scheme. At this order a proper definition of …

An exploratory study of heavy-light semileptonic form factors using distillation

Peter Boyle, Felix Erben, Michael Marshall +3

We present our exploratory study with the aim of simulating heavy-light semileptonic form factors as part of the RBC-UKQCD charm (to bottom) physics programme. We are using a disti…

Universal critical behavior in tensor models for four-dimensional quantum gravity

Astrid Eichhorn, Johannes Lumma, Antonio D. Pereira +1

Four-dimensional random geometries can be generated by statistical models with rank-4 tensors as random variables. These are dual to discrete building blocks of random geometries.…

Effect of particle contact on the electrical performance of NTC-epoxy composite thermistors

Daniella B. Deutz, Sybrand van der Zwaag, Pim Groen

As demand rises for flexible electronics, traditionally prepared sintered ceramic sensors must be transformed into fully new sensor materials that can bend and flex in use and inte…

Two-dimensional perturbative scalar QFT and Atiyah-Segal gluing

Santosh Kandel, Pavel Mnev, Konstantin Wernli

We study the perturbative quantization of 2-dimensional massive scalar field theory with polynomial (or power series) potential on manifolds with boundary. We prove that it fits in…

Large Higgs quartic coupling and (A)DM from extended Bosonic Technicolor

Mads T. Frandsen, Wei-Chih Huang

We propose novel bosonic Technicolor models augmented by an gauge group and scalar doublet. Dynamical breaking of induced by technifermion condensation triggers…

Topology optimization of heat sinks for instantaneous chip cooling using a transient pseudo-3D thermofluid model

Tao Zeng, Hu Wang, Mengzhu Yang +1

With the increasing power density of electronics components, the heat dissipation capacity of heat sinks gradually becomes a bottleneck. Many structural optimization methods, inclu…

An algebraic framework for noncommutative bundles with homogeneous fibres

Tomasz Brzeziński, Wojciech Szymański

An algebraic framework for noncommutative bundles with (quantum) homogeneous fibres is proposed. The framework relies on the use of principal coalgebra extensions which play the ro…

Higgs boson emerging from the dark

Chengfeng Cai, Hong-Hao Zhang, Giacomo Cacciapaglia +2

We propose a new non-thermal mechanism of dark matter production based on vacuum misalignment. A global -charge asymmetry is generated at high temperatures, under which both the…

Lorentz invariance violations in the interplay of quantum gravity with matter

Astrid Eichhorn, Alessia Platania, Marc Schiffer

We explore the interplay of matter with quantum gravity with a preferred frame to highlight that the matter sector cannot be protected from the symmetry-breaking effects in the gra…

Dark Matter meets Quantum Gravity

Manuel Reichert, Juri Smirnov

We search for an extension of the Standard Model that contains a viable dark matter candidate and that can be embedded into a fundamental, asymptotically safe, quantum field theory…

Formal Verification of Dynamic and Stochastic Behaviors for Automotive Systems

Li Huang, Tian Liang, Eun-Young Kang

Formal analysis of functional and non-functional requirements is crucial in automotive systems. The behaviors of those systems often rely on complex dynamics as well as on stochast…

Strong-field-driven dynamics and high-harmonic generation in interacting 1D systems

Sandra de Vega, Joel D. Cox, Fernando Sols +1

We explore the roles of electronic band structure and Coulomb interactions in solid-state HHG by studying the optical response of linear atomic chains and carbon nanotubes to inten…

First-passage and first-hitting times of Levy flights and Levy walks

V. V. Palyulin, G. Blackburn, M. A. Lomholt +4

For both Levy flight and Levy walk search processes we analyse the full distribution of first-passage and first-hitting (or first-arrival) times. These are, respectively, the times…
