• Title: Tunneling time and Faraday/Kerr effects in $\mathcal{PT}$-symmetric systems
• Authors: Vladimir Gasparian, Peng Guo, Antonio P\'erez-Garrido, and Esther J\'odar
• Abstract summary: Similarities of two phenomena are discussed, both exhibit a phase transition-like anomalous behaviour in certain range of model parameters. Anomalous behaviour of tunneling time and Faraday/Kerr angles in $mathcalPmathcalT$-symmetric systems is caused by the motion of poles of scattering amplitudes in energy/frequency complex plane.

• Abstract: We review the generalization of tunneling time and anomalous behaviour of Faraday and Kerr rotation angles in parity and time ($\mathcal{P}\mathcal{T}$)-symmetric systems. Similarities of two phenomena are discussed, both exhibit a phase transition-like anomalous behaviour in certain range of model parameters. Anomalous behaviour of tunneling time and Faraday/Kerr angles in $\mathcal{P}\mathcal{T}$-symmetric systems is caused by the motion of poles of scattering amplitudes in energy/frequency complex plane.

  entropy dynamics as an indicator of physical behavior in an open two-state system with balanced gain and loss is presented. We distinguish the perspective taken in utilizing the conventional framework of Hermitian-adjoint states from an approach that is based on biorthogonal-adjoint states and a third case based on an isospectral mapping.

  We consider a system of interacting spinless fermions on a two-leg triangular ladder with $pi/2$ magnetic flux per triangular plaquette. Microscopically, the system exhibits a U(1) symmetry corresponding to the conservation of total fermionic charge, and a discrete $mathbbZ$ symmetry. At the intersection of the three phases, the system features a critical point with an emergent SU(2) symmetry.

  We investigate the dynamics of out-of-time-order correlators (OTOCs) in a non-Hermitian kicked rotor model. In the unbroken phase of $mathcalPT$ symmetry, the OTOCs increase monotonically and eventually saturate with time. Just beyond the phase transition points, the OTOCs increase in the power-laws of time, with the exponent larger than two.

  Floquet symmetry protected second-order topological phases in a simple but insightful two-dimensional spin-1/2 lattice. We show that corner localized $mathbbZ$ symmetry broken operators commute and anticommute with the one-period time evolution operator. We propose a means to detect the signature of such modes in experiments and discuss the effect of imperfections.

In anomalous phase, the value of one of Faraday rotation angles may turn negative, and both angles suffer spectral singularities and yield strong enhancement near singularities.

  We compute the geometric phases acquired in both unitary and dissipative Jaynes-Cummings models.

We show the geometric phase is robust, exhibiting a vanishing correction under a non-unitary evolution.
