Cím: Minimum Entropy Production Effect on a Quantum Scale
Szerző: ;
Dátum: 2021

(2021)
The discovery of quantized electric conductance by the group of van Wees in 1988 was a major breakthrough in physics. A decade later, the group of Schwab has proven the existence of quantized thermal conductance. Advancing ...
Cím: Star Formation History in the Illustris TNG Simulation
Szerző: ; ; ;

(Cambridge, 2021)
We processed the catalogue data for all snapshots of the Illustris TNG100 cosmological simulation and collected every calculated property of the galaxies formed at different redshifts. With this dataset we can statistically ...
Cím: Estimating GRBs' cosmological distances

(2023)
Several thousand gamma-ray bursts have been observed but more than 500 events have known distances. Numerous papers have shown huge structures in the Universe based on GRBs. We want to examine the distribution of the GRBs’ ...
Cím: Redshift dependence of GRBs' observed parameters
Szerző: ; ;
Dátum: 2023

GRBs are extremely energetic short cosmic transients. Due to their huge energy output in a short time they can be observed at very large cosmological distances. Actually, they sample the whole observable Universe. As a ...
Cím: The clustering of gamma-ray bursts in the Hercules–Corona Borealis Great Wall: the largest structure in the Universe?
Szerző: ; ; ; ; ; ; ;
Dátum: 2020

(2020)
The Hercules–Corona Borealis Great Wall is a statistically significant clustering of gamma-ray bursts (GRBs) around redshift 2. Motivated by recent theoretical results indicating that a maximal Universal structure size may ...
Cím: Micromachining using the high energy flat-top beam of a femtosecond pulse UV laser system: micropillar prefabrication
Szerző: ; ; ; ; ; ;
Dátum: 2023

(2023)
Ablation with ultrashort laser pulses as a surface micromachining tool was studied using a hybrid die-excimer laser system that has high energy per laser pulse (tens of mJ’s), about 600 fs pulse duration and low repetition ...
Cím: GROUPS OF WORLDVIEW TRANSFORMATIONS IMPLIED BY ISOTROPY OF SPACE
Szerző: ; ;
Dátum: 2021

(2021)
Given any Euclidean ordered field, Q, and any 'reasonable' group, G, of (1+3)-dimensional spacetime symmetries, we show how to construct a model M-G of kinematics for which the set W of worldview transformations between ...
Cím: A Potential-Based Quantization Procedure of the Damped Oscillator

"Today, two of the most prosperous fields of physics are quantum computing and spintronics. In both, the loss of information and dissipation play a crucial role. In the present work, we formulate the quantization of the ...
Cím: Does the GRB Duration Depend on Redshift?
Szerző: ; ; ; ;
Dátum: 2022
Feltöltve: 2023-03-21
(2022)
Several hundred gamma-ray burst (GRB) redshifts have been determined to date. One of the other important properties—besides the distance—of the GRBs is the duration of the burst. In this paper, we analyse these two important ...
Cím: Investigations of isotropy and homogeneity of spacetime in first-order logic
Szerző: ; ;
Dátum: 2022
Feltöltve: 2023-03-28
(2022)
We investigate the logical connection between (spatial) isotropy, homogeneity of space, and homogeneity of time within a general axiomatic framework. We show that isotropy not only entails homogeneity of space, but also, ...
