Homoclinic RG flows, or when relevant operators become irrelevant

Christian B. Jepsen, Fedor K. Popov

We study an supersymmetric quantum field theory with symmetry. Working in dimensions, we calculate the beta functions up to second loop orde…

Many Body Scars as a Group Invariant Sector of Hilbert Space

Kiryl Pakrouski, Preethi N. Pallegar, Fedor K. Popov +1

We present a class of Hamiltonians for which a sector of the Hilbert space invariant under a Lie group , which is not a symmetry of , possesses the essential properties o…

Hagedorn Temperature in Large Majorana Quantum Mechanics

Gabriel Gaitan, Igor R. Klebanov, Kiryl Pakrouski +2

We discuss two types of quantum mechanical models that couple large numbers of Majorana fermions and have orthogonal symmetry groups. In models of vector type, only one of the symm…

Supersymmetric Tensor Model at Large and Small

Fedor K. Popov

We study the supersymmetric quantum field theory of a scalar superfield with a tetrahedral interaction. In the large limit the theory is dominated by the mel…

Majorana Fermion Quantum Mechanics for Higher Rank Tensors

Igor R. Klebanov, Preethi N. Pallegar, Fedor K. Popov

We study quantum mechanical models in which the dynamical degrees of freedom are real fermionic tensors of rank five and higher. They are the non-random counterparts of the Sachdev…

Characters of different secular effects in various patches of de Sitter space

E. T. Akhmedov, U. Moschella, F. K. Popov

There are at least three different types of secular effects in the two-point correlation functions in scalar quantum field theories in de Sitter space-time. The first one is specif…
