Deterministic Chaos vs Integrable Models
Stefano Negro, Fedor K. Popov, Jacob Sonnenschein
In this work we present analytical and numerical evidences that classical integrable models possessing infinitely many degrees of freedom unexpectedly exhibit some features that ar…
Measurement-induced phase transition in teleportation and wormholes
Alexey Milekhin, Fedor K. Popov
We demonstrate that some quantum teleportation protocols exhibit measurement induced phase transitions in Sachdev-Ye-Kitaev model. Namely, Kitaev-Yoshida and Gao-Jafferis-Wall prot…
Non-Perturbative Defects in Tensor Models from Melonic Trees
Fedor K. Popov, Yifan Wang
The Klebanov-Tarnopolsky tensor model is a quantum field theory for rank-three tensor scalar fields with certain quartic potential. The theory possesses an unusual large limit…
Beyond the Berry Phase: Extrinsic Geometry of Quantum States
Alexander Avdoshkin, Fedor K. Popov
Consider a set of quantum states parameterized by taken from some parameter space . We demonstrate how all geometric properties of this manifold of states a…
Kronecker anomalies and gravitational striction
Alexander M. Polyakov, Fedor K. Popov
We study quantum field theories in which the number of degrees of freedom changes discontinuously across the momentum space. This discontinuity which we call "Kronecker anomaly" le…
Supersymmetry in QCD coupled to fermions
Fedor K. Popov
We consider dimensional Yang-Mills theory with gauge group coupled to a massive Majorana fermion field in an adjoint representation and a number of massless Dirac or Majo…
