Summary
This study generalizes the anti-de Sitter/conformal field theory correspondence to nonrelativistic systems. It introduces a new holographic framework applicable to ultracold atoms and quantum critical phenomena.
Area of Science:
- Theoretical Physics
- Quantum Field Theory
- Condensed Matter Physics
Background:
- The anti-de Sitter/conformal field theory (AdS/CFT) correspondence links gravitational theories to quantum field theories.
- Nonrelativistic conformal field theories (NCFTs) describe critical phenomena in systems like ultracold atoms but lack a standard holographic description.
- Galilean invariance is a key symmetry in nonrelativistic systems.
Purpose of the Study:
- To generalize the AdS/CFT correspondence to NCFTs with Galilean invariance.
- To establish a holographic framework for understanding quantum critical behavior in nonrelativistic systems.
- To explore the properties of novel gravitational solutions relevant to NCFTs.
Main Methods:
- Construction of a family of metrics that realize Galilean symmetries as isometries.
- Solving Einstein's gravity with a negative cosmological constant coupled to pressureless dust.
- Developing a holographic dictionary to map between bulk and boundary theories.
- Calculating two-point correlators in the proposed holographic framework.
Main Results:
- A family of gravitational solutions realizing nonrelativistic conformal symmetries was constructed.
- These solutions are associated with gravity and pressureless dust, with bulk superconductors as a possible realization.
- A holographic dictionary was developed, and two-point correlators consistent with NCFTs were derived.
- The emergent bulk geometry possesses two additional noncompact dimensions.
Conclusions:
- The study successfully generalizes the holographic principle to nonrelativistic conformal field theories.
- The developed framework provides a new tool for studying ultracold atoms and quantum criticality.
- The presence of extra dimensions in the bulk geometry is a key feature of this novel correspondence.

Gauss's Law
If a closed surface does not have any charge inside where an electric field line can terminate, then the electric field line entering the surface at one point must necessarily exit at some other point of the surface. Therefore, if a closed surface does not have any charges inside the enclosed volume, then the electric flux through the surface is zero. What happens to the electric flux if there are some charges inside the enclosed volume? Gauss's law gives a quantitative answer to this question.
Second Uniqueness Theorem
Consider a region consisting of several individual conductors with a definite charge density in the region between these conductors. The second uniqueness theorem states that if the total charge on each conductor and the charge density in the in-between region are known, then the electric field can be uniquely determined.
In contrast, consider that the electric field is non-unique and apply Gauss's law in divergence form in the region between the conductors and the integral form to the surface...

Electric Field of a Non Uniformly Charged Sphere
Gauss's law states that the electric flux through any closed surface equals the net charge enclosed within the surface. This law is beneficial for determining the expressions for the electric field for a particular charge distribution if the electric flux is known.
Consider a non-uniformly charged sphere, for which the density of charge depends only on the distance from a point in space and not on the direction. Such a sphere has a spherically symmetrical charge distribution. Here, the electric...

The Principle of Superposition and the Gravitational Field
The principle of superposition applies to gravitational forces of objects that are sufficiently far apart. It states that the net gravitational force on a point object is the vector sum of the gravitational forces on it due to various objects. The principle helps calculate the force by listing the individual forces and then vectorially summing them up. However, it should be noted that the principle of superposition is not always apparent. In the presence of a second force, the first force could...
Electric Field of Two Equal and Opposite Charges
Atoms generally contain the same number of positively and negatively charged particles, protons, and electrons. Hence, they are electrically neutral. However, the centers of the positive and negative charges do not always coincide. In such a scenario, the electric field of an atom may not be zero.
A separation of the positive and negative charges can lead to a weak, remnant effect of the positive and negative charges. The expectation is that the more the distance between the positive and...

Gauss's Law: Spherical Symmetry
A charge distribution has spherical symmetry if the density of charge depends only on the distance from a point in space and not on the direction. In other words, if the system is rotated, it doesn't look different. For instance, if a sphere of radius R is uniformly charged with charge density ρ0, then the distribution has spherical symmetry. On the other hand, if a sphere of radius R is charged so that the top half of the sphere has a uniform charge density ρ1 and the bottom half has a uniform...
