*
Exotic R4, a differentiable 4-manifold, homeomorphic but not diffeomorphic to the Euclidean space R
4
*
Exotic sphere
In an area of mathematics called differential topology, an exotic sphere is a differentiable manifold ''M'' that is homeomorphic but not diffeomorphic to the standard Euclidean ''n''-sphere. That is, ''M'' is a sphere from the point of view of a ...
, a differentiable ''n''-manifold, homeomorphic but not diffeomorphic to the ordinary ''n''-sphere

Exotic atom
An exotic atom is an otherwise normal atom in which one or more sub-atomic particles have been replaced by other particles of the same charge. For example, electrons may be replaced by other negatively charged particles such as muons (muonic atoms ...
, an atom with one or more electrons replaced by other negatively charged particles
*
Exotic hadron
Exotic hadrons are subatomic particles composed of quarks and gluons, but which – unlike "well-known" hadrons such as protons, neutrons and mesons – consist of more than three valence quarks. By contrast, "ordinary" hadrons contain just tw ...
**
Exotic baryon
Exotic baryons are a type of hadron (bound states of quarks and gluons) with half-integer spin, but with a quark content different from the three quarks (''qqq'') present in conventional baryons. An example would be pentaquarks, consisting of f ...
, bound states of 3 quarks and additional particles
**
Exotic meson
Exotic mesons are mesons that have quantum numbers not possible in the quark model; some proposals for non-standard quark model mesons could be:
; glueballs or gluonium: Glueballs have no valence quarks at all.
; tetraquarks: Tetraquarks have t ...
, non-quark model mesons

Exotic matter
There are several proposed types of exotic matter:
* Hypothetical particles and states of matter that have "exotic" physical properties that would violate known laws of physics, such as a particle having a negative mass.
* Hypothetical partic ...
, a hypothetical concept of particle physics

Exotic pet
An exotic pet is a pet which is relatively rare or unusual to keep, or is generally thought of as a wild species rather than as a domesticated pet. The definition varies by culture, location, and over time—as animals become firmly enough est ...

Exotic Shorthair
The Exotic Shorthair is a breed of cat developed as a short-haired version of the Persian. The Exotic is similar to the Persian in many ways, including temperament and conformation, a flat nose and face with the exceptions of the short dense coa ...

*Exotic species (or
introduced species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived ther ...

Exotic dancer
A stripper or exotic dancer is a person whose occupation involves performing striptease in a public adult entertainment venue such as a strip club. At times, a stripper may be hired to perform at a bachelor party or other private event.

Exotic derivative
An exotic derivative, in finance, is a derivative which is more complex than commonly traded "vanilla" products. This complexity usually relates to determination of payoff; see option style.
The category may also include derivatives with a non-s ...
