Extreme Terahertz Nonlinear Phononics by Coherence-Imprinted Control of Hybrid Order
Liang Luo, Avinash Khatri, Martin Mootz +12
Coherent control of quantum materials has progressed along two major fronts: nonlinear phononics, which reshapes lattices to induce emergent states, and Floquet engineering, which…
Terahertz-nanoscale visualization of the microscopic spin-charge architecture of colossal magnetoresistive switching
Samuel Haeuser, Randall K. Chan, Richard H. J. Kim +4
Resolving sub-10 nm spin switching and the associated terahertz (THz) electrodynamics during the colossal magnetoresistance (CMR) transition is a definitive frontier in reaching th…
Extreme Terahertz Magnon Multiplication Induced by Resonant Magnetic Pulse Pairs
C. Huang, L. Luo, M. Mootz +7
Nonlinear interactions of spin-waves and their quanta, magnons, have emerged as prominent candidates for interference-based technology, ranging from quantum transduction to antifer…
Discovery of an Unconventional Quantum Echo by Interference of Higgs Coherence
C. Huang, M. Mootz, L. Luo +9
Nonlinearities in quantum systems are fundamentally characterized by the interplay of phase coherences, their interference, and state transition amplitudes. Yet the question of how…
Chirality manipulation of ultrafast phase switchings in a correlated CDW-Weyl semimetal
Bing Cheng, Di Cheng, Tao Jiang +8
A recently emerging concept for quantum phase discovery is the controlled gapping of linear band crossings in topological semimetals. For example, achieving topological superconduc…
Discovery of Light-induced Metastable Martensitic Anomaly Controlled by Single-Cycle Terahertz Pulses
X. Yang, B. Song, C. Vaswani +9
We report on an ultrafast photoinduced phase transition with a strikingly long-lived Martensitic anomaly driven by above-threshold single-cycle terahertz (THz) pulses in NbSn.…
Light-Driven Raman Coherence as a Non-Thermal Route to Ultrafast Topology Switching
C. Vaswani, L. -L. Wang, D. H. Mudiyanselage +14
A grand challenge underlies the entire field of topology-enabled quantum logic and information science: how to establish topological control principles driven by quantum coherence…
Competing Orders and Ultrafast Energy Transfer at the Quantum Limit in a NbSn Superconductor Probed by Terahertz Electrodynamics
X. Yang, X. Zhao, C. Vaswani +10
We report the low-energy electrodynamics of a moderately clean A15 superconductor (SC) following ultrafast excitation to understand and manipulate terahertz (THz) quasi--particle (…
Theory of Ultrafast Spin--Charge Quantum Dynamics in Strongly Correlated Systems Controlled by Femtosecond Photoexcitation: an Application to Insulating Antiferromagnetic Manganites
P. C. Lingos, M. D. Kapetanakis, M. Mootz +2
We use a non-equilibrium many-body theory that engages the elements of transient coherence, correlation, and nonlinearity to describe changes in the magnetic and electronic phases…
