Odd-parity electronic order near the semiconductor limit
Jack Tregidga, Dibyata Rout, Johannes Hielscher +3
Identifying materials platforms in which dilute carriers experience strong Coulomb interactions is a central challenge in the search for interaction-driven quantum phases. In such…
Persistence of charge density wave fluctuations in the absence of long-range order in a hole-doped kagome metal
Terawit Kongruengkit, Andrea N. Capa Salinas, Ganesh Pokharel +3
The kagome metals VSb ( = K, Rb, Cs) exhibit a complex interplay between charge density wave (CDW) order and superconductivity. In this study, we use ultrafast cohere…
Quantum decoherence by magnetic fluctuations in a magnetic topological insulator
Ruben Saatjian, Simon Dovrén, Kohtaro Yamakawa +3
In magnetic topological insulators, spontaneous time-reversal symmetry breaking by intrinsic magnetic order can gap the topological surface spectrum, resulting in exotic properties…
Picosecond expansion in LaAlO3 resonantly driven by infrared-active phonons
Jakob Gollwitzer, Jeffrey Z. Kaaret, Y. Eren Suyolcu +19
We investigate the ultrafast structural dynamics of LaAlO3 thin films driven by short mid-infrared laser pulses at 20 THz. Time-resolved X-ray diffraction reveals an immediate latt…
Effects of doping on polar order in SrTiO from first-principles modeling
Alex Hallett, John W. Harter
SrTiO is an incipient ferroelectric and an exceptionally dilute superconductor with a dome-like dependence on carrier concentration. Stabilization of a polar phase through ch…
Absence of Phonon Softening across a Charge Density Wave Transition due to Quantum Fluctuations
Yubi Chen, Terawit Kongruengkit, Andrea Capa Salinas +9
Kagome metals have emerged as a frontier in condensed matter physics due to their potential to host exotic quantum states. Among these, CsV3Sb5 has attracted significant attention…
