Jul 12, 2024 · If one uses the double cover S U ( 2) = S p i n ( 3) of the rotation group S O ( 3), the spinor (S) and vector (V) representations satisfy. S ⊗ S = 1 ⊕ V. which is just the fact well-known to physicists that if you take the tensor product of two spinor representations, you get a scalar and a vector.
Jul 13, 2024 · “Even though we now know that isn't our universe, it did inspire some people to study ideas of higher dimensions from the mid-20th century,” says Cumrun Vafa, a theorist at Harvard University. Ultimately, that led to Vafa's field of study, string theory.
2 days ago · Cumrun Vafa generalized T-duality from circles to arbitrary manifolds, creating the mathematical field of mirror symmetry. Daniel Friedan, Emil Martinec and Stephen Shenker further developed the covariant quantization of the superstring using conformal field theory techniques.
Jul 2, 2024 · Amineh Mohseni, Miguel Montero, Cumrun Vafa, Irene Valenzuela. In this note, we propose a generalized notion of distance between vacua in the theory of a scalar field ϕ with scalar potential V(ϕ) coupled to gravity.

Jul 2, 2024 · Jul 2024. Leading expert on particle physics and string theory, and their mathematical content. Discovered or elaborated symmetries and dualities of super-symmetric field theory and string theory.
Jul 13, 2024 · In joint work with Shing-Tung Yau (BIMSA, YMSC, Tsinghua, Harvard Math, Harvard CMSA, and Harvard Physics departments), Cody Long (Harvard Physics), and Cumrun Vafa (Harvard Math and Physics departments) he worked on geometry moduli spaces of sheaves with non-homolomorphic support and their associated non-BPS (non-holomorphic ...
Jul 18, 2024 · The terminology was motivated since the collection of string theory vacua had previously come to be called the landscape of string theory vacua. The idea is to imagine the remaining EFTs not “in” this landscape to form a space “away from the landscape”, whence the colorful imagery of a swampland.
