A new review looks at an important and often overlooked aspect of physics that suggested symmetry in the particle zoo and how it could be broken.
At the beginning of the 20th century the development of quantum mechanics and relativity changed the face of physics forever. While much has been written about this revolution, less is known about the development of the CPT theorem — vital to quantum field theory and modern physics.
A new paper published in EPJ H and authored by Alexander S. Blum and Andres Martınez de Velasco from Max Planck Institute for the History of Science, Berlin, looks at the roots of CPT theorem and its influence over modern physics.

The superconductor antimony sulfide selenide is a potential candidate for solar materials, but this depends on understanding how to boost its efficiency.
As climate change continues to present itself as the most pressing threat facing our planet, researchers push to find efficient and clean alternatives to fossil fuels. Foremost among this research is harnessing free energy from the sun. Doing this efficiently requires advanced knowledge of the qualities of materials used in the construction of solar cells.
In a new paper published in EPJ Plus, Maykel Courel from the Centro Universitario de los Valles (CUValles), Universidad de Guadalajara, Mexico, and co-authors, look at the limitations of the material antimony sulfide selenide, which has emerged as a potential candidate for solar cell fabrication.

Despite being vital to the study of superconductivity in cuprate materials the physical origins of the pseudogap remain a mystery.
Over three decades since the discovery of high-temperature superconductivity in ceramic cuprate materials, investigating the electronic states in cuprate materials to advance the understanding of the superconducting phase and related phenomena has become of incredible importance.
In a new paper published in the EPJ B, Ernesto Raposo from the Federal University of Pernambuco, Brazil, and his co-authors, look at one of the essential physical properties of cuprate superconducting compounds, the pseudogap, which describes a state where the Fermi surface of a material possesses a partial energy gap.

Research published in EPJ Plus shows that it is possible to classify rocks according to the size of the particles they contain during quarrying, using a portable Raman spectrometer.
The nature and potential uses of a sedimentary rock depends on the size of the particles or grains that they are composed from, and particle sizing is an important part of rock classification. A group of researchers led by Iacopo Osticioli of Istituto di Fisica Applicata “N. Carrara”, Florence, Italy has shown that it is possible to size particles and identify rock samples rapidly and accurately while they are being quarried using a portable Raman spectrometer. This work has now been published in the journal EPJ Plus.

New theoretical analysis considers cases where the electrons are allowed to exist beyond the boundaries of semiconducting quantum wires – with important implications for their performance.
Thin, semiconducting wires have attracted much recent attention in physics – both in experiments and theoretical analysis. Named ‘quantum wires,’ these structures are often coated in insulating materials, and several previous studies have now explored how the mismatch between the insulating properties of both materials can influence their performance. Through new analysis published in EPJ B, Nguyen Nhu Dat and Nguyen Thi Thuc Hien at Duy Tan University, Vietnam, show that thinner wires with less insulating coatings can improve the mobility of the electrons they carry.

A new approach to simulating traffic considers how drivers will change lanes at different rates depending on the density of traffic surrounding them
Many urban areas worldwide are now rapidly expanding, often with major negative impacts on traffic congestion. To address this issue, researchers have constructed models aiming to simulate the flow of traffic – but so far, they haven’t widely considered the impacts of drivers changing lanes. In a new study published in EPJ B, Nikita Madaan and Sapna Sharma at the Thapar Institute of Engineering and Technology, India, show how the lane-changing behaviours observed in real drivers can be incorporated into simulations of two-lane roads.

A new paper in EPJ Plus introduces a novel method of searching for a type of dark matter known as axions; a modified version of this technique may have useful ‘real life’ applications.
Most of the universe is now thought to consist of dark matter: mysterious substances which, because they don’t interact with light or any other kind of electromagnetic radiation, are almost impossible to detect. Physicists have been searching for it for decades, using different techniques; Nicolò Crescini, now of Institut Néel, Grenoble, France, developed a novel method of searching for one type of dark matter, axions, when working at the Laboratori Nazionali di Legnaro, Padova, Italy. This work has now been published in the journal EPJ Plus.
