Nonresonant Raman control of ferroelectric polarization
Jiaojian Shi, Christian Heide, Haowei Xu +15
Important advances have recently been made in the search for materials with complex multi-phase landscapes that host photoinduced metastable collective states with exotic functiona…
Terahertz-induced tunnel ionization drives coherent Raman-active phonon in Bismuth
Bing Cheng, Patrick L. Kramer, Mariano Trigo +6
Driving coherent lattice motion with THz pulses has emerged as a novel pathway for achieving dynamic stabilization of exotic phases that are inaccessible in equilibrium quantum mat…
Observation of polarization density waves in SrTiO3
Gal Orenstein, Viktor Krapivin, Yijing Huang +23
The nature of the "failed" ferroelectric transition in SrTiO3 has been a long-standing puzzle in condensed matter physics. A compelling explanation is the competition between ferro…
Ultrafast lattice disordering can be accelerated by electronic collisional forces
Gilberto A. de la Pena Munoz, Alfredo A. Correa, Shan Yang +11
In the prevalent picture of ultrafast structural phase transitions, the atomic motion occurs in a slowly varying potential energy surface determined adiabatically by the fast elect…
Hard X-ray Generation and Detection of Nanometer-Scale Localized Coherent Acoustic Wave Packets in SrTiO and KTaO
Yijing Huang, Peihao Sun, Samuel W. Teitelbaum +21
We demonstrate that the absorption of femtosecond x-ray pulses can excite quasi-spherical high-wavevector coherent acoustic phonon wavepackets using an all x-ray pump and probe sca…
Ultrafast measurements under anisotropic strain reveal near equivalence of competing charge orders in TbTe
Soyeun Kim, Gal Orenstein, Anisha G. Singh +3
We report ultrafast reflectivity measurements of the dynamics of the order parameter of the charge density wave (CDW) in TbTe under anisotropic strain. We observe an increase i…
