Path-integral Monte Carlo estimator for the dipole polarizability of quantum plasma
Juha Tiihonen, David Trejo-Garcia, Tapio T. Rantala +1
We present a path-integral Monte Carlo estimator for calculating the dipole polarizability of interacting Coulomb plasma in the long-wavelength limit, i.e., the optical region. We…
A Quantum Monte Carlo study of the structural, energetic, and magnetic properties of two-dimensional (2D) H and T phase VSe
Daniel Wines, Juha Tiihonen, Kayahan Saritas +2
Previous works have controversially claimed near-room temperature ferromagnetism in two-dimensional (2D) VSe, with conflicting results throughout the literature. These discrepa…
A Combined First Principles Study of the Structural, Magnetic, and Phonon Properties of Monolayer CrI
Daniel Staros, Guoxiang Hu, Juha Tiihonen +6
The first magnetic 2D material discovered, monolayer (ML) CrI, is particularly fascinating due to its ground state ferromagnetism. Yet, because monolayer materials are difficul…
Towards Quantum Monte Carlo Forces on Heavier Ions: Scaling Properties
Juha Tiihonen, Raymond C. Clay, Jaron T. Krogel
Quantum Monte Carlo (QMC) forces have been studied extensively in recent decades because of their importance with spectroscopic observables and geometry optimization. Here we bench…
Towards Utility-based Prioritization of Requirements in Open Source Environments
Alexander Felfernig, Martin Stettinger, Müslüm Atas +5
Requirements Engineering in open source projects such as Eclipse faces the challenge of having to prioritize requirements for individual contributors in a more or less unobtrusive…
Improved management of issue dependencies in issue trackers of large collaborative projects
Mikko Raatikainen, Quim Motger, Clara Marie Lüders +7
Issue trackers, such as Jira, have become the prevalent collaborative tools in software engineering for managing issues, such as requirements, development tasks, and software bugs.…
Static field-gradient polarizabilities of small atoms and molecules in finite temperature
Juha Tiihonen, Ilkka Kylänpää, Tapio T. Rantala
In this work, we propose new field-free estimators for static field-gradient polarizabilities in finite temperature PIMC simulation. Namely, dipole--quadrupole polarizability ,…
