Summary
Anomalous fluids exhibit superfluid-like behavior without drag, carrying energy and charge. Unlike superfluids, these anomalous currents transport entropy, with thermodynamic laws determining their precise amounts.
Area of Science:
- Condensed Matter Physics
- High-Energy Physics
- Quantum Field Theory
Background:
- Anomalous fluids possess unique properties related to chiral magnetic and vortical effects.
- Understanding dissipationless currents in these systems is crucial for theoretical advancements.
Purpose of the Study:
- To investigate the existence of a
- no-drag frame
- for anomalous fluids.
- To characterize the behavior of energy, charge, and entropy currents within this frame.
- To determine the thermodynamic constraints on these anomalous currents.
Main Methods:
- Theoretical analysis of anomalous fluid dynamics.
- Application of the second law of thermodynamics.
- Calculations within chiral kinetic theory.
- Investigation in the context of quark-gluon plasma.
Main Results:
- A frame was identified where stationary obstacles experience no drag from anomalous fluids.
- Energy and charge currents persist in this frame, mimicking superfluidity.
- Anomalous chiral currents were shown to transport entropy, distinguishing them from ordinary superfluids.
- The second law of thermodynamics was found to fully determine these nondissipative currents.
Conclusions:
- The study reveals a novel
- no-drag frame
- for anomalous fluids with dissipationless chiral currents.
- Thermodynamic principles dictate the properties of these anomalous currents, offering a new perspective on fluid behavior.

Chirality is a term that describes the lack of mirror symmetry in an object. In other words, chiral objects cannot be superposed on their mirror images. For example, our feet are chiral, as the mirror image of the left foot, the right foot, cannot be superposed on the left foot.
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

When a force is applied parallel to the top surface of a solid, it resists the applied force due to the internal frictional forces between the layers of the solid known as shearing resistance. However, when the force is removed, the shearing forces restore the original shape of the solid. Other deformation forces also cause temporary changes in shape if the forces are not beyond a threshold magnitude. Solids tend to retain their shape, making the study of their rest and motion easier. Beyond...

Fluids differ from solids primarily in their molecular structure and stress response. Solids have tightly packed molecules with strong intermolecular forces, maintaining their shape and resisting deformation. In contrast, fluids have molecules spaced farther apart with weaker forces, allowing them to flow and deform easily.
Fluids, which include both liquids and gases, are substances that deform continuously under shearing stress. For example, water and oil are liquids with molecules that can...

Nonideal liquid solutions, also known as real solutions, do not strictly follow Raoult's law. Raoult's law is a rule of thumb in physical chemistry. However, not all mixtures adhere to this law due to varying molecular interactions. For example, in an acetone/chloroform solution, the individual vapor pressures of the components are lower than expected, resulting in a total vapor pressure below that predicted by Raoult's law, causing a negative deviation.On the other hand, in an ethanol/water...

Fluids can be classified into Newtonian and non-Newtonian fluids based on their response to shear stress. Newtonian fluids have a linear relationship between shear stress and the shear strain rate, following Newton's law of viscosity. Their viscosity remains constant regardless of the shear rate, making their behavior predictable and easier to analyze. Common examples include water, air, oil, and gasoline.
In contrast, non-Newtonian fluids do not follow Newton's law of viscosity, and...
