“…Fractional quantum Hall systems are another intriguing direction to engineer prethermal correlated phases using external driving. While a vast series of Abelian filling fractions have been experimentally realized (Stormer et al, 1999), more elusive fractional quantum Hall states (Moore and Read, 1991;Read and Rezayi, 1999) with non-Abelian quasiparticles are well-known to prefer finetuned or multi-body interactions for stabilization (Greiter et al, 1991), while simultaneously incurring tremendous interest for potential applications in topological quantum computing and beyond (Nayak et al, 2008). In principle, Landau levels in ultraclean electron gases provide a natural separation of energy scales for Floquet engineering.…”

We review recent progress in utilizing ultrafast light-matter interaction to control the macroscopic properties of quantum materials. Particular emphasis is placed on photoinduced phenomena that do not result from ultrafast heating effects but rather emerge from microscopic processes that are inherently nonthermal in nature. Many of these processes can be described as transient modifications to the free energy landscape resulting from the redistribution of quasiparticle populations, the dynamical modification of coupling strengths and the resonant driving of the crystal lattice. Other pathways result from the coherent dressing of a material's quantum states by the light field. We discuss a selection of recently discovered effects leveraging these mechanisms, as well as the technological advances that led to their discovery. A road map for how the field can harness these nonthermal pathways to create new functionalities is presented.

“…In addition to driving the aforementioned short-lived phenomena, it is also possible for the resonant excitation of longitudinal optical (LO) phonons to permanently switch magnetic ordering in a ferrimagnetic iron-garnet [25]. Can the same mechanism be used to switch antiferromagnetic ordering as well?…”

Phononic manipulation of antiferromagnetic domains in NiO

The interaction between the crystal lattice and spins appears to be a very efficient mechanism for non-thermal manipulation of magnetic order. A particularly intriguing question is whether lattice vibrations can also be used to control or even switch domains in collinear antiferromagnets, where all other mechanisms fail. To answer this question, here we study the magnetic effects induced by tunable and narrow-band infrared optical pulses in single crystals of antiferromagnetic nickel oxide. Our measurements reveal that a resonant excitation in the vicinity of the frequency of longitudinal optical phonons leads to the displacement of antiferromagnetic domains in NiO, potentially revealing a promising method to manipulate antiferromagnetic order.

“…Отметим, что в этой области также появляется интерес к переходу к использованию лазерных импульсов за пределами оптического диапазона, которые позволяют напрямую возбуждать фононные моды с последующей конвертацией в динамические или квазистатические деформации [145]. На основе этого подхода уже было реализовано переключение намагниченности в ферритегранате за счет деформаций, полученных путем нелинейного преобразования фононных мод, возбужденных в среднем инфракрасном диапазоне [146].…”

Employing short laser pulses with a duration below 100 fs for changing magnetic state of magnetically-ordered media has developed into a distinct branch of magnetism —femtomagnetism which aims at controlling magnetization at ultimately short timescales. Among plethora of femtomagnetic phenomena, there is a class related to impact of femtosecond pulses on magnetic anisotropy of materials and nanostructures which defines orientation of magnetization, magnetic resonance frequencies and spin waves propagation. We present a review of main experimental results obtained in this field. We consider basic mechanisms responsible for a laser-induced change of various anisotropy types: magnetocrystalline, magnetoelastic, interfacial, shape anisotropy, and discuss specifics of these processes in magnetic metals and dielectrics. We consider several examples and describe features of magnetic anisotropy changes resulting from ultrafast laser-induced heating, impact of laser-induced dynamic and quasistatic strains and resonant excitation of electronic states. We also discuss perspectives of employing various mechanisms of laser-induced magnetic anisotropy change for enabling processes prospective for developing devices. We consider precessional magnetization switching for opto-magnetic information recording, generation of high-frequency strongly localized magnetic excitations and fields for magnetic nanotomography and hybrid magnonics, as well as controlling spin waves propagation for optically-reconfigurable magnonics. We further discuss opportunities which open up in studies of ultrafast magnetic anisotropy changes because of using short laser pulses in infrared and terahertz ranges.
