RESEARCH OVERVIEW
Topological Acoustics & Quantum Analogies
I am a research scientist at the NSF-funded New Frontiers of Sound (NewFoS) center, where I explore topological acoustics – an emerging field that lets us observe and control sound waves in unprecedented ways. Topological acoustics gives us a “new pair of ears” to hear hidden properties of sound, enabling quantum-like phenomena in classical acoustic systems.
01
Quantum Analogies for QIS
Leveraging acoustic spin waves as analogs to quantum systems. Building robust platforms for massive information storage without quantum fragility.
02
Topological RF Devices
Developing topologically protected RF acoustic devices—filters, waveguides, and acoustic transistors for next-gen 5G/6G networks.
03
Environmental Sensing
Pioneering geometric-phase-based acoustic sensing for environmental monitoring, seismic detection, and infrastructure safety.
PILLAR 01
Quantum Analogies for Quantum Information Systems
By exploiting the coherence and quantum analogies of spins in topological acoustic waves, we can build robust, scalable platforms for storing, processing, and retrieving massive amounts of information – without the fragility of actual quantum qubits. We use sound waves to mimic quantum behavior, creating entangled-like acoustic states (nonseparable states) that behave similarly to entangled particles.
✦ Robust Acoustic Qubits
Unlike fragile quantum bits, acoustic modes don’t require extreme cryogenics. We investigate coherent phononic states as information carriers that resist decoherence, enabling large-scale, room-temperature quantum information processing.
✦ Massive Information Storage
Acoustic waves in topological phononic structures encode information in their phase and spin. We’re building foundations for miniaturized acoustic devices that process sound-encoded data beyond current silicon chips.
✦ Full Workflow
Combining theoretical modeling, numerical simulations, and laboratory experiments. From computational models to 3D-printed prototypes—translating fundamental acoustic coherence into working QIS analog devices.
PILLAR 02
Topological Acoustic Wave RF Devices
Developing topologically protected RF acoustic devices that could transform wireless communications. Topological acoustic metamaterials allow one-way, lossless propagation of sound waves—like an electrical topological insulator guiding electrons with zero resistance.
One-Way Waveguides
Sound travels in one direction without reflections or losses even if the path bends or encounters defects—ideal for RF signal distribution with improved signal integrity.
Acoustic Transistors
Acoustic transistors use stimuli to induce topological phase changes that switch sound flow on/off, enabling logic operations with sound at radio frequencies.
Industrial Impact
A “generational revolution” in wireless tech—topological acoustic components replacing electronic RF filters for 5G/6G networks and IoT sensors.
PILLAR 03
Topological Acoustic Sensing of the Natural Environment
Pioneering geometric-phase-based acoustic sensing that uses topological sound waves to detect minute environmental changes. Acoustic waves sent through natural media reveal changes in material properties through phase shifts and scattering patterns with unparalleled sensitivity.
🌍 Monitoring Climate Change Effects
Tracking permafrost thawing in Arctic forests and soil moisture changes in wildfire-prone regions. Networks of seismic acoustic sensors detect shifts in the geometric phase of waves traveling through the ground—serving as early warnings of thawing permafrost. “We can use this sensing technology as a way of warning people that there are changes taking place that may impact infrastructure.” — NewFoS Director Pierre Deymier
