On Worst-Case Guarantees for Graph-Based Nearest-Neighbor Search
Majid Daliri, Mohammadreza Daneshvaramoli, Purna Dutta +4
Graph-based nearest neighbor search algorithms like HNSW, DiskANN, NSG, and others have surged in popularity in recent years due to their excellent empirical performance in compari…
Phonon angular momentum transfer torque
Verena Brehm, Daniel A. Bustamante Lopez, Shu Zhang +1
Angular momentum in solids is carried by (quasi)particles such as magnons, plasmons, and phonons, and coupling between these reservoirs enables diverse hybrid phenomena. Here, we i…
Precessional modes of phonon angular momentum
Daniel A. Bustamante Lopez, Dominik M. Juraschek
Magnons are collective precessional excitations of electron spins and are ubiquitous in emerging information technologies. Here, we show that the crystal lattice can support an ana…
Light-induced weak ferromagnetism through nonlinear magnonic rectification
Tom Kahana, Daniel A. Bustamante Lopez, Dominik M. Juraschek
Rectification describes the generation of a quasistatic component from an oscillating field, such as an electric polarization in optical rectification, or a structural distortion i…
Ultrafast simultaneous manipulation of multiple ferroic orders through nonlinear phonon excitation
Daniel A. Bustamante Lopez, Dominik M. Juraschek, Michael Fechner +3
Recent experimental studies have demonstrated the possibility of utilizing strong terahertz pulses to manipulate individual ferroic orders on pico- and femtosecond timescales. Here…
Transient gap generation in BaFeAs driven by coherent lattice vibrations
Jacob A. Warshauer, Daniel Alejandro Bustamante Lopez, Qingxin Dong +2
The electronic structure and the magnetic properties of iron-based superconductors are highly sensitive to the pnictogen height. Coherent excitation of the phonon by femto…
