Investigation of glitches induced by single-crystal diamond compound refractive lenses based on crystal orientation
(Peer reviewed; Journal article, 2019)Single-crystal diamond is considered as an ideal material for compound refractive lenses (usually abbreviated to “CRLs”) mainly due to its stability when bathed in strong X-ray radiation. Since CRLs come into operation by ... -
Lil3 dimerization and chlorophyll binding in Arabidopsis thaliana
(Peer reviewed; Journal article, 2015)The two-helix light harvesting like (Lil) protein Lil3 belongs to the family of chlorophyll binding light harvesting proteins of photosynthetic membranes. A function in tetrapyrrol synthesis and stabilization of geranylgeraniol ... -
Log-density gradient covariance and automatic metric tensors for Riemann manifold Monte Carlo methods
(Peer reviewed; Journal article, 2023)A metric tensor for Riemann manifold Monte Carlo particularly suited for nonlinear Bayesian hierarchical models is proposed. The metric tensor is built from symmetric positive semidefinite log-density gradient covariance ... -
Multimessenger Constraints for Ultradense Matter
(Peer reviewed; Journal article, 2022)Recent rapid progress in neutron-star (NS) observations offers great potential to constrain the properties of strongly interacting matter under the most extreme conditions. In order to fully exploit the current observational ... -
New tests for trend in time censored recurrent event data
(Peer reviewed; Journal article, 2024-01)We consider testing for trend in recurrent event data. More precisely, for such data we consider testing of the null hypothesis of data coming from a renewal process. The new tests are essentially obtained by considering ... -

Nonrelativistic effective field theories with enhanced symmetries and soft behavior
(Peer reviewed; Journal article, 2022)We systematically explore the landscape of nonrelativistic effective field theories with a local S-matrix and enhanced symmetries and soft behavior. The exploration is carried out using both conventional quantum field ... -
Optimisation of Thimble simulations and quantum dynamics of multiple fields in real time
(Peer reviewed; Journal article, 2022)We apply the Generalised Thimble approach to the computation of exact path integrals and correlators in real-time quantum field theory. We first investigate the details of the numerical implementation and ways of optimizing ... -
Order parameter dynamics of the non-linear sigma model in the large N limit
(Peer reviewed; Journal article, 2020)We study non-equilibrium order parameter dynamics of the non-linear sigma model in the large N limit, using Keldysh formalism. We provide a scheme for obtaining stable numerical solution of the Keldysh saddle point equations ... -
Perturbative thermal QCD: Formalism and applications
(Peer reviewed; Journal article, 2020)In this review article, we discuss the current status and future prospects of perturbation theory as a means of studying the equilibrium thermodynamic and near-equilibrium transport properties of deconfined QCD matter. We ... -
Quantum corrections to slow-roll inflation: scalar and tensor modes
(Peer reviewed; Journal article, 2021)Inflation is often described through the dynamics of a scalar field, slow-rolling in a suitable potential. Ultimately, this inflaton must be identified with the expectation value of a quantum field, evolving in a quantum ... -
Quench, thermalization, and residual entropy across a non-Fermi liquid to Fermi liquid transition
(Peer reviewed; Journal article, 2020)We study the thermalization, after sudden and slow quenches, in an interacting model having a quantum phase transition from a Sachdev-Ye-Kitaev (SYK) non-Fermi liquid (NFL) to a Fermi liquid (FL). The model has SYK fermions ... -
Real-time quantum dynamics, path integrals and the method of thimbles
(Peer reviewed; Journal article, 2019)Direct numerical evaluation of the real-time path integral has a well-known sign problem that makes convergence exponentially slow. One promising remedy is to use Picard-Lefschetz theory to flow the domain of the field ... -
Realistic in-medium heavy-quark potential from high statistics lattice QCD simulations
(Peer reviewed; Journal article, 2019)We present our first results on a direct computation of the complex in-medium heavy quark potential from realistic lattice QCD simulations. Ensembles with Nτ = 12 from the HotQCD and TUMQCD collaboration offer unprecedented ... -
Reconstructing parton distribution functions from Ioffe time data: from Bayesian methods to Neural Networks
(Peer reviewed; Journal article, 2019)The computation of the parton distribution functions (PDF) or distribution amplitudes (DA) of hadrons from first principles lattice QCD constitutes a central open problem. In this study, we present and evaluate the efficiency ... -
The role of initial state radiation in quenched jets
(Peer reviewed; Journal article, 2022)Jet quenching in heavy ion collisions and in particular the sub-structure of quenched jets are promising tools for investigating the microscopic processes underlying jet quenching and the background medium's response to ... -
Science AMA Series: Ask the Society of Environmental Toxicology and Chemistry (SETAC) anything about Pharmaceuticals in the environment!
(Journal article, 2017)The Society of Environmental Toxicology and Chemistry (SETAC) is hosting the SETAC North America 38th annual meeting this week and we have tied this AMA to a specific session, “Pharmaceuticals in the environment: Potential ... -
Spectral function for overoccupied gluodynamics from classical lattice simulations
(Peer reviewed; Journal article, 2019)We study the spectral properties of an overoccupied gluonic system far from equilibrium. Using classical Yang–Mills simulations and linear response theory, we determine the statistical and spectral functions. We measure ... -
