Large Field Inflation and Gravitational Entropy
Nemanja Kaloper, Matthew Kleban, Albion Lawrence +1
Large field inflation can be sensitive to perturbative and nonperturbative quantum corrections that spoil slow roll. A large number of light species in the theory, which occur…
Boson Stars from Self-Interacting Dark Matter
Joshua Eby, Chris Kouvaris, Niklas Grønlund Nielsen +1
We study the possibility that self-interacting bosonic dark matter forms star-like objects. We study both the case of attractive and repulsive self-interactions, and we focus parti…
Cheap arbitrary high order methods for single integrand SDEs
Kristian Debrabant, Anne Kværnø
For a particular class of Stratonovich SDE problems, here denoted as single integrand SDEs, we prove that by applying a deterministic Runge-Kutta method of order we obtain me…
A natural Coleman-Weinberg theory explains the diphoton excess
Oleg Antipin, Matin Mojaza, Francesco Sannino
It is possible to delay the hierarchy problem, by replacing the standard Higgs-sector by the Coleman-Weinberg mechanism, and at the same time ensure perturbative naturalness throug…
On the validity of the perturbative description of axions during inflation
Ricardo Z. Ferreira, Jonathan Ganc, Jorge Noreña +1
Axions play a central role in many realizations of large field models of inflation and in recent alternative mechanisms for generating primordial tensor modes in small field models…
White Dwarf Critical Tests for Modified Gravity
Rajeev Kumar Jain, Chris Kouvaris, Niklas Grønlund Nielsen
Scalar-tensor theories of gravity can lead to modifications of the gravitational force inside astrophysical objects. We exhibit that compact stars such as white dwarfs provide a un…
The Tangled Nature Model of evolutionary dynamics reconsidered: structural and dynamical effects of trait inheritance
Christian Walther Andersen, Paolo Sibani
The Tangled Nature Model of biological and cultural evolution features interacting agents which compete for limited resources and reproduce in an error prone fashion and at a rate…
On the K-theory of C*-algebras arising from integral dynamics
Selçuk Barlak, Tron Omland, Nicolai Stammeier
We investigate the -theory of unital UCT Kirchberg algebras arising from families of relatively prime numbers. It is shown that is the d…
Quantum Critical Behaviour of Semi-Simple Gauge Theories
Jacob Kamuk Esbensen, Thomas A. Ryttov, Francesco Sannino
We study the perturbative phase diagram of semi-simple fermionic gauge theories resembling the Standard Model. We investigate an gauge theory with Dirac flavors where w…
Self-excitation of surface plasmon polaritons
V. G. Bordo
The novel effect of self-excitation of surface plasmons (SESP) in a plasmonic nanocavity is predicted and its theory is developed from first principles. It is assumed that the cavi…
Template Composite Dark Matter : SU(2) gauge theory with 2 fundamental flavours
Vincent Drach, Ari Hietanen, Claudio Pica +2
We present a non perturbative study of SU(2) gauge theory with two fundamental Dirac flavours. We discuss how the model can be used as a template for composite Dark Matter (DM). We…
Wilson Fermions with Four Fermion Interactions
Jarno Rantaharju, Vincent Drach, Ari Hietanen +2
We present a lattice study of a four fermion theory, known as Nambu Jona-Lasinio (NJL) theory, via Wilson fermions. Four fermion interactions naturally occur in several extensions…
Gradient flow and IR fixed point in SU(2) with Nf=8 flavors
Viljami Leino, Tuomas Karavirta, Jarno Rantaharju +4
We study the running of the coupling in SU(2) gauge theory with 8 massless fundamental representation fermion flavours, using the gradient flow method with the Schrödinger function…
Quasidiagonal traces on exact -algebras
James Gabe
Recently, it was proved by Tikuisis, White and Winter that any faithful trace on a separable, nuclear -algebras in the UCT class is quasidiagonal. Building on their work, w…
Data-driven Workflows for Microservices
Larisa Safina, Manuel Mazzara, Fabrizio Montesi
Microservices is an architectural style inspired by service-oriented computing that has recently started gaining popularity. Jolie is a programming language based on the microservi…
The data sharing advantage in astrophysics
S. B. F. Dorch, T. M. Drachen, O. Ellegaard
We present here evidence for the existence of a citation advantage within astrophysics for papers that link to data. Using simple measures based on publication data from NASA Astro…
A micro-macro acceleration method for the Monte Carlo simulation of stochastic differential equations
Kristian Debrabant, Giovanni Samaey, Przemysław Zieliński
We present and analyse a micro-macro acceleration method for the Monte Carlo simulation of stochastic differential equations with separation between the (fast) time-scale of indivi…
Planckian Interacting Massive Particles as Dark Matter
Mathias Garny, McCullen Sandora, Martin S. Sloth
The Standard Model could be self-consistent up to the Planck scale according to the present measurements of the Higgs mass and top quark Yukawa coupling. It is therefore possible t…
Radiatively Induced Fermi Scale in Grand Unified Theories
Tommi Alanne, Aurora Meroni, Francesco Sannino +1
We consider Grand Unified Theories in which the hierarchy between the unification and the Fermi scale emerges radiatively. Within the Pati-Salam framework, we show that it is possi…
The nature of massive neutrinos and multiple mechanisms in neutrinoless double beta decay
Aurora Meroni
Determining the nature -Dirac or Majorana- of massive neutrinos is one of the most pressing and challenging problems in the field of neutrino physics. We discuss how one can possib…
repAIrC: A Tool for Ensuring Data Consistency by Means of Active Integrity Constraints
Luís Cruz-Filipe, Michael Franz, Artavazd Hakhverdyan +3
Consistency of knowledge repositories is of prime importance in organization management. Integrity constraints are a well-known vehicle for specifying data consistency requirements…
Nonperturbative results for two-index conformal windows
Georg Bergner, Thomas A. Ryttov, Francesco Sannino
Via large and small relations we derive nonperturbative results about the conformal window of two-index theories. Using Schwinger-Dyson methods as well as four-loops results…
Sequentially split -homomorphisms between -algebras
Selçuk Barlak, Gábor Szabó
We define and examine sequentially split -homomorphisms between -algebras and -dynamical systems. For a -homomorphism, the property of being seque…

Jarno Rantaharju, Teemu Rantalaiho, Kari Rummukainen +1
We study SU(2) gauge theory with two Dirac fermions in the adjoint representation of the gauge group on the lattice. Using clover improved Wilson fermion action with hypercubic tru…
