“…In particular, with the increasing frustration due to increasing |J 2 | the transition temperature gradually decreases down to zero at R = −1/4. A possible crossover to the first-order behavior was suggested by the EFT (Bobák et al 2016) but not confirmed by either MC ( Žukovič 2021) or CMF (Schmidt and Godoy 2021).…”

“…This frustrated model is also interesting from the experimental point of view, since it can be applied to some real materials (Matsuda et al 2010;Tsirlin et al 2010). The ground state of the J 1 − J 2 Ising model was investigated in some earlier papers (Houtappel 1950;Kudō and Katsura 1976;Katsura et al 1986) but its critical behavior was studied only recently by the effective field theory (EFT) (Bobák et al 2016), the MC simulation ( Žukovič et al 2020; Žukovič 2021), cluster mean-field (CMF) (Schmidt and Godoy 2021) and machine learning (ML) (Corte et al 2021;Acevedo et al 2021) approaches. For smaller degree of frustration, namely within the interval −1/4 < R < 0, the critical behavior resembles that for the square lattice.…”

Light modelling, simulation, and photometric calculations are by now common tasks in the lighting design process. These practices contribute to the definition and comparison of suitable layout arrangements and help predict the impact of lighting devices. Those tasks demand the use of tools to support the simulation of different scenarios, the analyses of their pros and cons according to different criteria (e.g., health and safety, perception, aesthetics, energy consumption, and costs), and decision-making. Digital twins have emerged as relevant technologies to simulate and visualize different ``what-if'' scenarios associated with physical entities and processes. In this paper, we investigate the state-of-the-art research concerning the use of digital twins for supporting lighting analysis in the urban/outdoor context. We also present and discuss challenges and research opportunities related to the design, implementation, and validation of digital twins in this domain.

NTNU is a university with an international focus, with headquarters in Trondheim and campuses in Ålesund and Gjøvik. NTNU has a main profile in science and technology, a variety of programmes of professional study, and great academic breadth that also includes the humanities, social sciences, economics, medicine, health sciences, educational science, architecture, entrepreneurship, art disciplines and artistic activities. NTNU has eight faculties, 55 departments, and NTNU University Museum with a total budget of NOK 10 billion, of which NOK 2,6 billion from external sources (2021). NTNU offers 356 study programs, as well as further education to more than 42000 from Norway and abroad enrolled in various bachelor, master, and PhD programs.NTNU in its current form was established by the King-in-Council in 1996 by the merger of the former University of Trondheim and other university-level institutions, with roots dating back to 1760, and has later also incorporated some former university colleges.NTNU is consistently ranked in the top one percentage among the world's universities, We are honored to offer, besides the scientific program of the conference, consisting in more than 45 high quality accepted papers in 8 scientific tracks, a rich and various series of social events, as usual for the spirit of this conference.
