    The Theoretical Advanced Study Institute or TASI is a four-week summer school in high-energy physics or astrophysics held yearly at the University of Colorado at Boulder.The school is meant primarily for advanced graduate students and consists of a series of pedagogical lectures on selected topics given by active researchers in the field.

  4. AdS/CFT correspondence - Wikipedia

    en.wikipedia.org/wiki/AdS/CFT_correspondence

    The application of quantum mechanics to physical objects such as the electromagnetic field, which are extended in space and time, is known as quantum field theory. [15] In particle physics , quantum field theories form the basis for our understanding of elementary particles, which are modeled as excitations in the fundamental fields.

  5. Quantum field theory - Wikipedia

    en.wikipedia.org/wiki/Quantum_field_theory

    In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. [ 1 ] : xi QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles .

  6. Quantum field theory in curved spacetime - Wikipedia

    Using perturbation theory in quantum field theory in curved spacetime geometry is known as the semiclassical approach to quantum gravity. This approach studies the interaction of quantum fields in a fixed classical spacetime and among other thing predicts the creation of particles by time-varying spacetimes [ 5 ] and Hawking radiation . [ 6 ]

  7. Operator product expansion - Wikipedia

    en.wikipedia.org/wiki/Operator_product_expansion

    In quantum field theory, the operator product expansion (OPE) is used as an axiom to define the product of fields as a sum over the same fields. [1] As an axiom, it offers a non-perturbative approach to quantum field theory. One example is the vertex operator algebra, which has been used to construct two-dimensional conformal field theories ...

    In theoretical physics, more specifically in quantum field theory and supersymmetry, supersymmetric Yang–Mills, also known as super Yang–Mills and abbreviated to SYM, is a supersymmetric generalization of Yang–Mills theory, which is a gauge theory that plays an important part in the mathematical formulation of forces in particle physics.
