In-plane anisotropic ground states are ubiquitous in correlated solids such as pnictides, cuprates and manganites. They can arise from doping Mott insulators and compete with phases such as superconductivity; however, their origins are debated. Strong coupling between lattice, charge, orbital and spin degrees of freedom results in simultaneous ordering of multiple parameters, masking the mechanism that drives the transition. Here we demonstrate that the orbital domains in a manganite can be… 
Light control of orbital domains: case of the prototypical manganite La0.5Sr1.5MnO4
Control of electronic and structural ordering in correlated materials on the ultrafast timescale with light is a new and emerging approach to disentangle the complex interplay of the charge, spin,
Multi-mode excitation drives disorder during the ultrafast melting of a C4-symmetry-broken phase
It is shown that a time-dependent mean-field theory of light-induced phase transitions fails to capture the order parameter dynamics in a single layered manganite and the role of disorder in ultrafast phase transitions in general is discussed.
Orbital ordering of ultracold alkaline-earth atoms in optical lattices
We report on a dynamical mean-field theoretical analysis of emerging low-temperature phases in multicomponent gases of fermionic alkaline-earth(-like) atoms in state-dependent optical lattices. Using
Laser-induced control of an electronic nematic quantum phase transition
Ultrafast techniques have emerged as promising methods to study and control quantum materials. To maintain the quantum nature of the systems under study, excess heating must be avoided. In this work,
Fluctuation control of nonthermal orbital order
Orbitally ordered states exhibit unique features which make them a promising platform for exploring the ultrafast dynamics of long-range order in solids: Their free energy typically has multiple
Reconfiguration of magnetic domain structures of ErFeO3 by intense terahertz free electron laser pulses
This work used intense THz pulses with pulse energies in the order of 10 mJ/pulse generated from the terahertz free electron laser (THz-FEL) to irradiate the ferromagnetic domains of ErFeO3 single crystal and found that the domain shape can be locally reconfigured by irradiating the THz − FEL pulses near the domain boundary.

Orbital correlations in doped manganites
Abstract.We review our recent X-ray scattering studies of charge and orbital order in doped manganites, with specific emphasis on the role of orbital correlations in Pr1-xCaxMnO3. For x=0.25, we find
Manganites at quarter filling: Role of Jahn-Teller interactions
We have analyzed different correlation functions in a realistic spin-orbital model for half-doped manganites. Using a finite-temperature diagonalization technique the CE phase was found in the
We propose the origin of the charge-ordered stripe structure with the orbital ordering observed experimentally in La_(1-x)Ca_(x)MnO_(3) (x=1/2, 2/3), in which the long-range Coulomb interaction plays
Charge ordering via electron-electron interactions in the colossal-magnetoresistive manganites
The coupled magnetic and charge-order transition observed in the manganites of the type R1-xMxMnO3 near half filling (x similar or equal to 1/2) is shown to be the result of the interplay between the

Control of the electronic phase of a manganite by mode-selective vibrational excitation
This work reports the ultrafast switching of the electronic phase of a magnetoresistive manganite via direct excitation of a phonon mode at 71 meV (17 THz), and reports the vibrationally driven bandgap collapse observed here, which is uniquely attributed to a large-amplitude Mn–O distortion.
Ferromagnetic, A-type, and charge-ordered CE-type states in doped manganites using jahn-teller phonons
The two-orbital model for manganites with both noncooperative and cooperative Jahn-Teller phonons is studied at hole density x = 0.5 using Monte Carlo techniques, and the insulating CE-type charge- and orbital-ordered state with the z-axis charge stacking observed in narrow-bandwidth manganite is stabilized in the simulations.
Orbital domain dynamics in a doped manganite.
We explore a number of novel effects near the orbital-order phase transition in a half-doped manganite, Pr0.5Ca0.5MnO3. To probe the unusual short-range orbital order in this system, we have
