Lattice Model of Ideal Walking

Abstract: We present preliminary studies of the SU(2) gauged NJL model with 2 flavors of fermions in the adjoint representation. The gauge model is infrared conformal and an additional NJL-type four fermion interaction, at large coupling, induces a chirally broken phase. In the symmetric phase the four fermion interaction is expected to influence the dynamics of the infrared fixed point and there may be a second order transition to the chirally broken phase. We study chiral symmetry breaking and the mass anomalous dimension at the infrared fixed point using the mode number of the Dirac operator.

Gravitational reheating after multi-field inflation

Abstract: It has recently been highlighted that details of the reheating process must be properly taken into account when constraining individual models of inflation with current high-precision CMB data, even in the case of single-field models. As inflation models with a non-minimal coupling between the gravity and inflaton sectors have recently attracted much attention, in this work we discuss reheating in this class of models, allowing for multiple inflaton fields. In such models, even in the absence of explicit interaction terms the inflaton sector can decay into matter as a result of its non-minimal coupling to gravity, thereby reheating the Universe gravitationally. Using the Bogoliubov approach we evaluate the gravitational decay rates of the inflaton sector, and analyse the reheating dynamics.

Dark Matter in multi-inert doublet models

Abstract: Dark Matter (DM), arising from an Inert Higgs Doublet, may either be light, below the W mass, or heavy, above about 525 GeV. While the light region may soon be excluded, the heavy region is known to be very difficult to probe with either Direct Detection (DD) experiments or the Large Hadron Collider (LHC). In this talk I will discuss that adding a second Inert Higgs Doublet helps to make the heavy DM region accessible to both DD and the LHC, by either increasing its couplings to the observed Higgs boson, or lowering its mass to 360 GeV < $m_{DM}$, or both.

Top-quark production at the LHC: Theory status and perspectives

Abstract: The current state of precision predictions for top-quark
production at the LHC will be reviewed. Special emphasis will be put on
the definition and the determination of the top-quark mass as a
fundamental parameter of the Standard Model. We will motivate, why
precision determinations of the top-quark mass are important in the
current high-energy run of the LHC and discuss the prerequisites in
theory for the extraction of a well-defined mass parameter in a given
renormalization scheme. We also discuss the implications for the
stability of the Higgs potential and the electroweak vacuum.

Massive neutrino signatures on the large-scale structure of the Universe

Abstract: Neutrinos are described as fundamental particles by the
standard model of particle physics. The fact that neutrinos are massive,
as demonstrated by neutrino oscillations experiments, point towards
physics beyond the standard model. One of the most important questions
in modern physics is: what are the neutrino masses? Current tightest
constrain on the sum of the neutrino masses arise from cosmological
observables. In order to extract the maximum information from current
and future surveys, as well as to avoid introducing biases in the values
of the cosmological parameters, it is of primordial importance to
understand, both at the linear and at the fully non-linear order, the
impact that massive neutrinos induce on the distribution of matter,
halos and galaxies. In this seminar I will present some of the effects
neutrinos induce on the Universe large-scale structure, among then the
clustering of matter, the clustering of dark matter halos, the abundance
of halos, the abundance of voids, their impact on the BAO peak and their
effects on the spatial distribution of neutral hydrogen in the
post-reionization era.

Tying Quantum Knots

Abstract: Knots are familiar entities that appear at a captivating nexus of art, technology, mathematics and science. Following a long period of theoretical investigation and development, they have recently attracted great experimental interest in classical contexts ranging from knotted DNA and nanostructures to vortex knots in fluids. In our work, we demonstrate the controlled creation and detection of knot solitons in the quantum-mechanical order parameter of a spinor Bose-Einstein condensate. Images of the superfluid reveal the circular shape of the soliton core and its associated linked rings. Our observations of the knot soliton establish an experimental foundation for future studies of their stability, dynamics and applications within quantum systems.

SUSY-phenomenology-based models of Higgs inflation

Abstract: Present CMB observation tightly constrains the amplitude of
the primordial tensor mode fluctuations. As phenomenologically
well-motivated and observationally viable models of inflation, I
discuss supersymmetric Higgs inflation type scenarios in this talk.
These are natural beyond-the-Standard Model extension of the popular
nonminimally coupled Higgs inflation model by Bezrukov-Shaposhnikov. In
this talk I will mainly focus on a scenario based on the supersymmetric
seesaw model.

From quarks and gluons to hadrons: chiral symmetry breaking in QCD

Abstract: The strong interactions are characterized by very different degrees of freedom at different energy scales. While the high energy regime of QCD is governed by quark-gluon dynamics, hadrons are the relevant degrees of freedom at low energies. The associated complex phase structure raises many fundamental questions, both experimentally and theoretically. In this talk I will address the question how chiral symmetry breaking and the spectrum of the light mesons emerge from the underlying quark-gluon dynamics. To this end, I employ functional renormalization group techniques, which will be reviewed briefly. As an application, I will present results on the scaling of vector meson masses towards the chiral symmetry breaking scale. If time permits, I will also show new results on the influence of the gauge sector of QCD on the curvature of the chiral phase boundary.

Gravity at the horizon: from the cosmic dawn to ultra-large scales

Abstract: Recent advances in cosmology provide both the motivation and the data to probe gravity on the largest scales available to observation. I will revise the landscape of gravitational theories, focusing on modern scalar-tensor theories and their cosmological implications. Then I will present the ongoing effort to test gravity in novel regimes such as the early universe, non-linear effects and ultra-large scales. I will also introduce the hi_class code (www.hiclass-code.net), which is central to this program.

Path integral quantum Monte Carlo simulation of atomic matter

Abstract: Feynman path integral approach to quantum mechanics and Monte Carlo simulations allow straightforward study of quantum many-body systems. Propagation of a quantum system in imaginary time (DMC, PIMC) can be used to find eigenstates or simulate thermal equilibrium, for example. I will present novel applications of PIMC to first-principles calculations of small molecules and simulation of a dissociation/recombination chemical reaction. Propagation in real time (RTPI), on the other hand, leads to conventional coherent quantum dynamics. Recently, we also found the incoherent propagation as a novel numerical tool for finding stationary states. I will present our first simulations of model systems in the way towards atoms and molecules. With Monte Carlo simulations the “fermion sign problem” arises as the major obstacle for simulations of large atomic systems. This and other development topics including possible extensions will be discussed.
