TASI Lectures on Large Tensor Models
Igor R. Klebanov, Fedor Popov, Grigory Tarnopolsky
The first part of these lecture notes is mostly devoted to a comparative discussion of the three basic large limits, which apply to fields which are vectors, matrices, or tenso…
Spectrum of Majorana Quantum Mechanics with Symmetry
Kiryl Pakrouski, Igor R. Klebanov, Fedor Popov +1
We study the quantum mechanics of 3-index Majorana fermions governed by a quartic Hamiltonian with symmetry. Similarly to the Sachdev-Ye-Kitaev model, this tenso…
Prismatic Large Models for Bosonic Tensors
Simone Giombi, Igor R. Klebanov, Fedor Popov +2
We study the symmetric quantum field theory of a bosonic tensor with sextic interactions. Its large limit is dominated by a positive-definite operator, whose…
Traversable wormholes in four dimensions
Juan Maldacena, Alexey Milekhin, Fedor Popov
We present a wormhole solution in four dimensions. It is a solution of an Einstein Maxwell theory plus charged massless fermions. The fermions give rise to a negative Casimir-like…
Ultraviolet phenomena in AdS self-interacting quantum field theory
Emil T. Akhmedov, Ugo Moschella, Fedor K. Popov
We study the one-loop corrections to the four-point function in the Anti de Sitter space-time for a field theory. Our calculation shows the existence of non-local counterterm…
Spectra of Eigenstates in Fermionic Tensor Quantum Mechanics
Igor R. Klebanov, Alexey Milekhin, Fedor Popov +1
We study the symmetric quantum mechanics of 3-index Majorana fermions. When the ranks are all equal, this model has a large limit which…
