Superconductivity is the phenomenon where a material exhibits zero electrical resistance below a certain temperature called the critical temperature (Tc).

Ferromagnets are magnetic materials that exhibit a spontaneous magnetization below a certain temperature called the Curie temperature (Tc). In a ferromagnet, all the magnetic moments of the atoms are aligned in the same direction, resulting in a strong net magnetization.

Freezing is the phase transition that occurs when a material changes from a liquid to a solid. During freezing, the molecules of the liquid lose energy and slow down, causing them to arrange themselves in a more ordered, crystalline structure.

Gallium Arsenide (GaAs) is a type of semiconductor material that has a relatively large bandgap, making it suitable for use in high-power and high-frequency electronic devices.

Metal-Insulator Transition (MIT) is the phenomenon where a material exhibits a sudden change in its electrical resistance at a certain temperature. This transition is often associated with a change in the material's electronic structure.

Topological Insulators are a type of topological insulator that has a conducting surface but an insulating bulk. This unique property is due to the material's non-trivial topological order.

Ferroelectricity is the phenomenon where a material exhibits a spontaneous polarization below a certain temperature called the Curie temperature (Tc). In a ferroelectric material, the electric dipoles of the atoms are aligned in the same direction, resulting in a net polarization.

Helium-4 is a type of quantum fluid that exhibits superfluidity below a temperature of 2.17 K. In a superfluid, the atoms flow without any viscosity, allowing it to exhibit unique properties such as zero thermal conductivity and the ability to flow through narrow channels without friction.

Magnetoresistance is the phenomenon where a material exhibits a change in its electrical resistance when subjected to a magnetic field. This change in resistance is caused by the interaction between the magnetic field and the material's charge carriers.

Spin Glass is a type of magnetic material that exhibits a disordered magnetic structure. In a spin glass, the magnetic moments of the atoms are randomly oriented, resulting in a zero net magnetization.

Electrochromism is the phenomenon where a material exhibits a change in its optical properties when subjected to an electric field. This change in optical properties is caused by the movement of ions or electrons within the material.

Fractional Quantum Hall State is a type of quantum material that exhibits a fractional quantum Hall effect. In a fractional quantum Hall state, the Hall conductance takes on fractional values, which are multiples of $e^2/h$, where $e$ is the elementary charge and $h$ is Planck's constant.

Magnetostriction is the phenomenon where a material exhibits a change in its magnetic properties when subjected to a mechanical stress. This change in magnetic properties is caused by the interaction between the mechanical stress and the material's magnetic moments.

Kitaev Honeycomb Model is a type of quantum material that exhibits a topological phase transition. In the Kitaev Honeycomb Model, the magnetic moments of the atoms are arranged in a honeycomb lattice, and the interactions between these magnetic moments give rise to a topological phase transition.

Thermoelectricity is the phenomenon where a material exhibits a change in its electrical resistance when subjected to a temperature gradient. This change in resistance is caused by the movement of charge carriers within the material due to the temperature gradient.
