text: It is a basic principle that an effect cannot come before the cause. Dispersive
relations that follow from this fundamental fact have proven to be an indispensable
tool in physics and engineering. They are most powerful in the domain of linear
response where they are known as Kramers-Kronig relations. However, when it comes
to nonlinear phenomena the implications of causality are much less explored, apart
from several notable exceptions. Here in this paper we demonstrate how to apply
the dispersive formalism to analyze the ultrafast nonlinear response in the context
of the paradigmatic nonlinear Kerr effect. We find that the requirement of causality
introduces a noticeable effect even under assumption that Kerr effect is mediated
by quasi-instantaneous off-resonant electronic hyperpolarizability. We confirm
this by experimentally measuring the time-resolved Kerr dynamics in GaAs by means
of a hybrid pump-probe Mach-Zehnder interferometer and demonstrate the presence
of an intrinsic lagging between amplitude and phase responses as predicted by
dispersive analysis. Our results describe a general property of the time-resolved
nonlinear processes thereby highlighting the importance of accounting for dispersive
effects in the nonlinear optical processes involving ultrashort pulses.

text: A rotating organic cation and a dynamically disordered soft inorganic cage
are the hallmark features of organic-inorganic lead-halide perovskites. Understanding
the interplay between these two subsystems is a challenging problem, but it is
this coupling that is widely conjectured to be responsible for the unique behavior
of photocarriers in these materials. In this work, we use the fact that the polarizability
of the organic cation strongly depends on the ambient electrostatic environment
to put the molecule forward as a sensitive probe of the local crystal fields inside
the lattice cell. We measure the average polarizability of the C/N–H bond stretching
mode by means of infrared spectroscopy, which allows us to deduce the character
of the motion of the cation molecule, find the magnitude of the local crystal
field, and place an estimate on the strength of the hydrogen bond between the
hydrogen and halide atoms. Our results pave the way for understanding electric
fields in lead-halide perovskites using infrared bond spectroscopy.

text: 'Lead halide perovskites enjoy a number of remarkable optoelectronic properties.
To explain their origin, it is necessary to study how electromagnetic fields interact
with these systems. We address this problem here by studying two classical quantities:
Faraday rotation and the complex refractive index in a paradigmatic perovskite
CH3NH3PbBr3 in a broad wavelength range. We find that the minimal coupling of
electromagnetic fields to the k⋅p Hamiltonian is insufficient to describe the
observed data even on the qualitative level. To amend this, we demonstrate that
there exists a relevant atomic-level coupling between electromagnetic fields and
the spin degree of freedom. This spin-electric coupling allows for quantitative
description of a number of previous as well as present experimental data. In particular,
we use it here to show that the Faraday effect in lead halide perovskites is dominated
by the Zeeman splitting of the energy levels and has a substantial beyond-Becquerel
contribution. Finally, we present general symmetry-based phenomenological arguments
that in the low-energy limit our effective model includes all basis coupling terms
to the electromagnetic field in the linear order.'

text: 'We use general symmetry-based arguments to construct an effective model suitable
for studying optical properties of lead halide perovskites. To build the model,
we identify an atomic-level interaction between electromagnetic fields and the
spin degree of freedom that should be added to a minimally coupled k⋅p Hamiltonian.
As a first application, we study two basic optical characteristics of the material:
the Verdet constant and the refractive index. Beyond these linear characteristics
of the material, the model is suitable for calculating nonlinear effects such
as the third-order optical susceptibility. Analysis of this quantity shows that
the geometrical properties of the spin-electric term imply isotropic optical response
of the system, and that optical anisotropy of lead halide perovskites is a manifestation
of hopping of charge carriers. To illustrate this, we discuss third-harmonic generation.'

text: We propose a simple method to measure nonlinear Kerr refractive index in mid-infrared
frequency range that avoids using sophisticated infrared detectors. Our approach
is based on using a near-infrared probe beam which interacts with a mid-IR beam
via wavelength-non-degenerate cross-phase modulation (XPM). By carefully measuring
XPM-induced spectral modifications in the probe beam and comparing the experimental
data with simulation results, we extract the value for the non-degenerate Kerr
index. Finally, in order to obtain the value of degenerate mid-IR Kerr index,
we use the well-established two-band formalism of Sheik-Bahae et al., which is
shown to become particularly simple in the limit of low frequencies. The proposed
technique is complementary to the conventional techniques, such as z-scan, and
has the advantage of not requiring any mid-infrared detectors.
