text: We study a polar molecule immersed in a superfluid environment, such as a
helium nanodroplet or a Bose–Einstein condensate, in the presence of a strong
electrostatic field. We show that coupling of the molecular pendular motion, induced
by the field, to the fluctuating bath leads to formation of pendulons—spherical
harmonic librators dressed by a field of many-particle excitations. We study the
behavior of the pendulon in a broad range of molecule–bath and molecule–field
interaction strengths, and reveal that its spectrum features a series of instabilities
which are absent in the field-free case of the angulon quasiparticle. Furthermore,
we show that an external field allows to fine-tune the positions of these instabilities
in the molecular rotational spectrum. This opens the door to detailed experimental
studies of redistribution of orbital angular momentum in many-particle systems.

text: We investigate the quantum interference shifts between energetically close
states, where the state structure is observed by laser spectroscopy. We report
a compact and analytical expression that models the quantum interference induced
shift for any admixture of circular polarization of the incident laser and angle
of observation. An experimental scenario free of quantum interference can thus
be predicted with this formula. Although this study is exemplified here for muonic
deuterium, it can be applied to any other laser spectroscopy measurement of ns-n′p
frequencies of a nonrelativistic atomic system, via an ns→n′p→n′′s scheme.

text: Quantum interference between energetically close states is theoretically investigated,
with the state structure being observed via laser spectroscopy. In this work,
we focus on hyperfine states of selected hydrogenic muonic isotopes, and on how
quantum interference affects the measured Lamb shift. The process of photon excitation
and subsequent photon decay is implemented within the framework of nonrelativistic
second-order perturbation theory. Due to its experimental interest, calculations
are performed for muonic hydrogen, deuterium, and helium-3. We restrict our analysis
to the case of photon scattering by incident linear polarized photons and the
polarization of the scattered photons not being observed. We conclude that while
quantum interference effects can be safely neglected in muonic hydrogen and helium-3,
in the case of muonic deuterium there are resonances with close proximity, where
quantum interference effects can induce shifts up to a few percent of the linewidth,
assuming a pointlike detector. However, by taking into account the geometry of
the setup used by the CREMA collaboration, this effect is reduced to less than
0.2% of the linewidth in all possible cases, which makes it irrelevant at the
present level of accuracy. © 2015 American Physical Society.

text: We give a comprehensive introduction into a diagrammatic method that allows
for the evaluation of Gutzwiller wave functions in finite spatial dimensions.
We discuss in detail some numerical schemes that turned out to be useful in the
real-space evaluation of the diagrams. The method is applied to the problem of
d-wave superconductivity in a two-dimensional single-band Hubbard model. Here,
we discuss in particular the role of long-range contributions in our diagrammatic
expansion. We further reconsider our previous analysis on the kinetic energy gain
in the superconducting state.

text: The recently proposed diagrammatic expansion (DE) technique for the full Gutzwiller
wave function (GWF) is applied to the Anderson lattice model. This approach allows
for a systematic evaluation of the expectation values with full Gutzwiller wave
function in finite-dimensional systems. It introduces results extending in an
essential manner those obtained by means of the standard Gutzwiller approximation
(GA), which is variationally exact only in infinite dimensions. Within the DE-GWF
approach we discuss the principal paramagnetic properties and their relevance
to heavy-fermion systems. We demonstrate the formation of an effective, narrow
f band originating from atomic f-electron states and subsequently interpret this
behavior as a direct itineracy of f electrons; it represents a combined effect
of both the hybridization and the correlations induced by the Coulomb repulsive
interaction. Such a feature is absent on the level of GA, which is equivalent
to the zeroth order of our expansion. Formation of the hybridization- and electron-concentration-dependent
narrow f band rationalizes the common assumption of such dispersion of f levels
in the phenomenological modeling of the band structure of CeCoIn5. Moreover, it
is shown that the emerging f-electron direct itineracy leads in a natural manner
to three physically distinct regimes within a single model that are frequently
discussed for 4f- or 5f-electron compounds as separate model situations. We identify
these regimes as (i) the mixed-valence regime, (ii) Kondo/almost-Kondo insulating
regime, and (iii) the Kondo-lattice limit when the f-electron occupancy is very
close to the f-state half filling, ⟨nˆf⟩→1. The nonstandard features of the emerging
correlated quantum liquid state are stressed.

text: We use the dual boson approach to reveal the phase diagram of the Fermi-Hubbard
model with long-range dipole-dipole interactions. By using a large-scale finite-temperature
calculation on a 64×64 square lattice we demonstrate the existence of a novel
phase, possessing an "ultralong-range" order. The fingerprint of this
phase - the density correlation function - features a nontrivial behavior on a
scale of tens of lattice sites. We study the properties and the stability of the
ultralong-range-ordered phase, and show that it is accessible in modern experiments
with ultracold polar molecules and magnetic atoms.

text: Atomic form factors are widely used for the characterization of targets and
specimens, from crystallography to biology. By using recent mathematical results,
here we derive an analytical expression for the atomic form factor within the
independent particle model constructed from nonrelativistic screened hydrogenic
wave functions. The range of validity of this analytical expression is checked
by comparing the analytically obtained form factors with the ones obtained within
the Hartee-Fock method. As an example, we apply our analytical expression for
the atomic form factor to evaluate the differential cross section for Rayleigh
scattering off neutral atoms.

text: "We investigate the occurrence of rotons in a quadrupolar Bose–Einstein condensate
confined to two dimensions. Depending on the particle density, the ratio of the
contact and quadrupole–quadrupole interactions, and the alignment of the quadrupole
moments with respect to the confinement plane, the dispersion relation features
two or four point-like roton minima or one ring-shaped minimum. We map out the
entire parameter space of the roton behavior and identify the instability regions.
We propose to observe the exotic rotons by monitoring the characteristic density
wave dynamics resulting from a short local perturbation, and discuss the possibilities
to detect the predicted effects in state-of-the-art experiments with ultracold
homonuclear molecules.\r\n"

text: We develop a microscopic theory describing a quantum impurity whose rotational
degree of freedom is coupled to a many-particle bath. We approach the problem
by introducing the concept of an “angulon”—a quantum rotor dressed by a quantum
field—and reveal its quasiparticle properties using a combination of variational
and diagrammatic techniques. Our theory predicts renormalization of the impurity
rotational structure, such as that observed in experiments with molecules in superfluid
helium droplets, in terms of a rotational Lamb shift induced by the many-particle
environment. Furthermore, we discover a rich many-body-induced fine structure,
emerging in rotational spectra due to a redistribution of angular momentum within
the quantum many-body system.

text: 'Optical transport represents a natural route towards fast communications,
and it is currently used in large scale data transfer. The progressive miniaturization
of devices for information processing calls for the microscopic tailoring of light
transport and confinement at length scales appropriate for upcoming technologies.
With this goal in mind, we present a theoretical analysis of a one-dimensional
Fabry-Perot interferometer built with two highly saturable nonlinear mirrors:
a pair of two-level systems. Our approach captures nonlinear and nonreciprocal
effects of light transport that were not reported previously. Remarkably, we show
that such an elementary device can operate as a microscopic integrated optical
rectifier.'
