Terahertz Light Unlocks Ultrafast Chirality Control in Non-Chiral Crystals
In a groundbreaking revelation, a Hamburg-Oxford research team has harnessed the power of terahertz light to induce chirality in non-chiral materials, opening the door to revolutionary applications in ultrafast memory devices and advanced optoelectronics. Led by Andrea cavalleri of the Max-Planck-Institut for the Structure and Dynamics of Matter, the team’s work, published in the journal Science, demonstrates how terahertz pulses can dynamically control matter at the atomic level.
what is Chirality?
Table of Contents
Chirality refers to objects that cannot be superimposed onto thier mirror images, much like the distinct left and right hands of a human. In chiral crystals, the spatial arrangement of atoms confers a specific “handedness,” influencing their optical and electrical properties. While naturally chiral materials are well-studied, the ability to induce chirality in non-chiral materials has remained elusive—until now.
Breaking the Symmetry
The team focused on antiferro-chiral crystals, a type of non-chiral material reminiscent of antiferro-magnetic systems, where magnetic moments anti-align in a staggered pattern,resulting in zero net magnetization. Similarly, antiferro-chiral crystals contain equal amounts of left- and right-handed substructures, rendering them overall non-chiral.
Using terahertz light, the researchers disrupted this balance in boron phosphate (BPO4), a non-chiral material. By exciting a specific terahertz frequency vibrational mode, they displaced the crystal lattice along the coordinates of other modes, creating a chiral state that persisted for several picoseconds.
“We exploit a mechanism termed nonlinear phononics,” explains Zhiyang Zeng, lead author of the study. “By exciting a specific terahertz frequency vibrational mode, we created a chiral state that survives for several picoseconds.”
Controlling Chirality with Light
One of the most striking findings was the ability to control the induced chirality by rotating the polarization of the terahertz light.”By rotating the polarization of the terahertz light by 90 degrees, we could selectively induce either a left- or right-handed chiral structure,” says Michael Först, a co-author of the study.This level of precision in controlling chirality opens up exciting possibilities for ultrafast memory devices and optoelectronic platforms. “This discovery opens up new possibilities for the dynamical control of matter at the atomic level,” says Cavalleri. “We are excited to see potential applications of this technology and how it can be used to create unique functionalities.”
Applications and Future Directions
The ability to induce chirality in non-chiral materials could revolutionize fields such as data storage and quantum computing. Ultrafast memory devices, for instance, could benefit from the ability to switch between chiral states on a picosecond timescale. Additionally, the technology could pave the way for more complex optoelectronic platforms, enabling new ways to manipulate light and matter.

Terahertz Pulses Induce Chirality in Non-Chiral Crystals: A Breakthrough in Material Science
In a groundbreaking discovery, researchers have demonstrated that terahertz pulses can induce chirality in a non-chiral crystal, opening new avenues for advanced material design and optical technologies. Published in Science on January 23, 2025, the study, led by Z. Zeng and colleagues, reveals how light can manipulate the structural properties of materials at the atomic level.Chirality, a property where a structure cannot be superimposed on its mirror image, is a essential concept in chemistry, biology, and physics. While naturally occurring chiral materials are common, artificially inducing chirality in non-chiral systems has remained a significant challenge—until now.
The Science Behind the Discovery
The team from the Max Planck Institute for the Structure and Dynamics of Matter used terahertz pulses, which lie between microwave and infrared light on the electromagnetic spectrum, to excite a non-chiral crystal. These ultra-short pulses, lasting only a few trillionths of a second, were able to temporarily alter the crystal’s atomic arrangement, creating a chiral structure.
“Photo-induced chirality in a nonchiral crystal represents a paradigm shift in how we think about material design,” said Z. Zeng,lead author of the study. “By using terahertz pulses, we can control and manipulate chirality with unprecedented precision.”
The researchers observed that the induced chirality was not permanent but could be sustained for a significant duration, depending on the material’s properties and the intensity of the terahertz pulses.this transient chirality opens up possibilities for dynamic optical devices and chiral sensors, which could revolutionize fields like photonics and quantum computing.
Implications for Future Technologies
The ability to induce chirality artificially has far-reaching implications. as an example, chiral materials are essential in pharmaceuticals, where the handedness of molecules can determine a drug’s efficacy and safety. By controlling chirality with light, scientists could develop more efficient drug synthesis methods.
Moreover, this discovery could lead to the creation of chiral metamaterials, which have unique optical properties not found in nature. These materials could be used in optical computing, data storage, and even invisibility cloaks.
