Summary
This study reveals universal Kardar-Parisi-Zhang physics in systems with broken time-translation symmetry. This finding explains critical scaling behaviors in diverse physical systems, from active matter to quantum devices.
Area of Science:
- Condensed Matter Physics
- Statistical Mechanics
- Nonlinear Dynamics
Background:
- Spontaneous breaking of time-translation symmetry leads to Goldstone modes.
- Limit cycle behavior of order parameters is observed in various physical systems.
- Understanding universal scaling properties is crucial in many-body physics.
Purpose of the Study:
- To investigate the universal behavior associated with Goldstone modes in systems with broken time-translation symmetry.
- To establish the connection between this universal behavior and Kardar-Parisi-Zhang (KPZ) physics.
- To predict and rationalize the emergence of KPZ physics in diverse systems.
Main Methods:
- Analysis of systems exhibiting spontaneous breaking of time-translation symmetry.
- Characterization of order parameter dynamics, specifically limit cycle behavior.
- Theoretical framework connecting Goldstone modes to KPZ scaling properties.
Main Results:
- Demonstrated a universal behavior linked to Goldstone modes and limit cycles.
- Established a strong connection between this universal behavior and Kardar-Parisi-Zhang physics.
- Showed that KPZ physics significantly influences scaling properties across all dimensions.
Conclusions:

24.2K
The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

14.7K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

02:54Trends in Lattice Energy: Ion Size and Charge
24.2K
An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a compound is a measure of the strength of this attraction. The lattice energy (ΔHlattice) of an ionic compound is defined as the energy required to separate one mole of the solid into its component gaseous ions. For the ionic solid sodium chloride, the lattice energy is the enthalpy change of the process:
