A US$2.5 million grant from the US Department of Energy (DOE) through its EPSCoR (Established initiative to Stimulate Competitive Research) initiative has given the University of Nebraska–Lincoln a significant boost.
Grant Boost Accelerates Quantum Materials Research at Nebraska
The goal of this funding infusion is to develop new infrastructure and human resources related to emergent quantum phenomena, as well as to advance frontier quantum materials research.
It supports UNL’s expanding aspirations in quantum materials research and marks the third major grant allocation in recent months for the university’s Emergent Quantum Materials and Technologies (EQUATE) Centre.

Targets: Ferroelectric Oxides and Re-Engineered Interfaces
A study program headed by Xia Hong, a professor of physics and astronomy at UNL, and a team of seven people forms the core of the grant’s agenda. Their goal is to develop previously unachievable quantum phases by utilizing ferroelectric oxides in conjunction with oxide and van der Waals materials.
In order to create novel states of matter, such as reversibly switching between metal and insulator or between magnetic and non-magnetic states, the team aims to create nanoscale control of ferroelectric phenomena in thin-film oxides. “The main objective is to design smaller and more energy-efficient devices by using nanoscale control of ferroelectricity to induce a new state of matter,” Hong stated.
There are three main thrusts identified:
- Investigating the possibility of reversible quantum phase transitions (metal ↔ insulator; magnetic ↔ non-magnetic) at the boundary of ferroelectric oxides and strongly-correlated oxides.
- Integrating ferroelectric insulators into polar metals and multiferroic systems (materials that include both magnetism and ferroelectricity) to enable low-energy data storage by utilising electric fields to transition magnetic states.
- To engineer new electrical and optical properties, ferroelectric thin-film superlattices and 2D van der Waals materials are stacked, rotation angles (Moiré engineering) are changed, and domain structures are altered.
If these initiatives are successful, there may be new platforms for smartphones and memory/logic devices that use less energy and perform better.

Infrastructure & Workforce: A Dual Investment
The DOE EPSCoR award prioritises personnel training and infrastructure development in addition to the purely scientific objectives. The project is initially scheduled for two years, however it may be extended for up to four more years.
Early-career scientists at both schools will receive funding, and the project will be carried out in partnership with South Dakota School of Mines & Technology (SDSMT). Alexey Lipatov (SDSMT), Tula Paudel (SDSMT), and Zuocheng Zhang (UNL) are three particular early-career faculty members mentioned. Undergraduates, post-doctoral researchers, and graduate students will also participate.
“The idea with EPSCoR is you’re looking into the infrastructure and human resource development, not just the research,” Professor Hong underlined.
The organisation hopes to establish a long-term centre in quantum materials science in the Midwestern United States by enhancing its tools and equipment and developing its human capital.
Momentum Builds for Nebraska’s Quantum Materials Hub
This grant expands on earlier funding achievements. Nearly five years ago, the National Science Foundation (NSF) awarded a $20 million grant to UNL to establish the EQUATE Centre.
More recently, UNL researchers received a $2 million NSF “Designing Materials to Revolutionise and Engineer Our Future” (DMREF) award and a $1.8 million NSF EPSCoR grant to study new two-dimensional (“flatland”) materials.
To put it briefly, Nebraska is establishing itself as a significant player in the field of quantum materials by emphasising energy-efficient devices, next-generation electronics, and novel materials research. That approach is supported by multi-institution alliances, strong academic leadership, and significant money.

Broader Implications for Technology and Society
Although the study focusses on materials science and complicated physics, the ramifications are extensive. If the team’s efforts are effective, they may result in:
- Gadgets with significantly higher energy efficiency that lower computer systems’ power usage.
- Quantum-phase transitions instead of conventional semiconductor switching to create logic and memory systems that are faster, smaller, and more powerful.
- Potentially revolutionising consumer electronics, memory storage, sensors, and quantum technologies are new families of 2D and oxide-membrane materials with tunable electrical and magnetic responses.
- A better regional environment for quantum training and research that supports workforce preparedness and innovation in new fields.
That’s the beauty of basic science, as Hong stated: “Even though you may not immediately see the impact, you are motivated by curiosity, the beauty of nature, and the fascination with how things behave.”

Looking Ahead: What to Watch
The UNL team will concentrate on reaching the major benchmarks of the three research thrusts throughout the course of the upcoming years. Realistic device prototypes, scalable production of innovative layered materials, and demonstrations of reversible quantum-phase switching will probably be used to gauge success. Progress will also be indicated by the expansion of infrastructure and the training of new scientists.
Nebraska’s EQUATE Centre could emerge as a leading centre for quantum materials and devices, contributing to the larger national movement for quantum information science, advanced electronics, and sustainable computing, given the high momentum and funding trajectory.
UNL is firmly establishing itself as a leader in quantum materials research with this $2.5 million investment, aiming to transform theoretical quantum phenomena into practical gadgets that could drive the next wave of technological advancements.
