Theoretical study demonstrates existence of giant photocaloric effects in ferroelectric perovskites
Solid-state cooling is a promising alternative cooling technique that does not rely on the use of gases or liquids, like conventional refrigeration systems, but instead utilizes the properties of solid materials to refrigerate. This alternative cooling approach could...
Researchers observe an antiferromagnetic diode effect in even-layered MnBi₂Te₄
Antiferromagnets are materials in which the magnetic moments of neighboring atoms are aligned in an alternating pattern, resulting in no net macroscopic magnetism. These materials have interesting properties that could be favorable for the development of spintronic...
Findings hint at a superfluid phase in ²⁹F and ²⁸O
Data collected by the SAMURAI spectrometer at RIKEN's RI Beam Factory (RIBF) in Japan recently led to the detection of a rare fluorine (F) isotope, known as 30F. This has opened interesting possibilities for the study of rare nuclear structures and corresponding...
Study predicts a new quantum anomalous crystal in fractionally filled moiré superlattices
Moiré superlattices, structures that arise when two layers of two-dimensional (2D) materials are overlaid with a small twist angle, have been the focus of numerous physics studies. This is because they have recently been found to host novel fascinating unobserved...
The experimental observation of a dissipative time crystal in a Rydberg gas
A dissipative time crystal is a phase of matter characterized by periodic oscillations over time, while a system is dissipating energy. In contrast with conventional time crystals, which can also occur in closed systems with no energy loss, dissipative time crystals...
Study demonstrates generation of orbital current via magnetization dynamics
Electrons inherently carry both spin and orbital angular momentum (i.e., properties that help to understand the rotating motions and behavior of particles). While some physicists and engineers have been trying to leverage the spin angular momentum of electrons to...
Visualizing the boundary modes of the charge density wave in a topological material
Charge density waves are quantum phenomena occurring in some materials, which involve a static modulation of conduction electrons and the periodic distortion of the lattice. These waves have been observed in numerous condensed matter materials, including...
A high-temperature superconductor with zero resistance that exhibits strange metal behavior
Researchers at Zhejiang University and Sun Yat-Sen University have gathered evidence of high-temperature superconductivity with zero resistance and strange metal behavior in a material identified in their previous studies.
A method to reversibly control Casimir forces using external magnetic fields
The so-called Casimir force or Casimir effect is a quantum mechanical phenomenon resulting from fluctuations in the electromagnetic field between two conducting or dielectric surfaces that are a short distance apart. Studies have shown that this force can be either be...
