History-Dependent Mode Selection in a Driven Holographic Superfluid
Bo-Xuan Ge
We study finite-rate mode selection among competing Landau-unstable modes in a holographic superfluid. The selected mode is not generally the instantaneous fastest-growing one, whi…
Taiji Resolving Power for the Transverse Scalar Mode of Gravitational Waves
Bo-Xuan Ge, Zhoujian Cao
We investigate how small a co-propagating transverse-scalar component can be resolved by Taiji in an already identified bright tensor chirp. Using a source-tracked tensor-null resp…
Neural variational framework for random Young-diagram limit shapes
Qian Chen, Bo-Xuan Ge
The paper introduces a neural variational approach that respects the combinatorial structure of random Young-diagram ensembles to compute their macroscopic limit shapes, and valida…
Massive boson stars: Waveform-based branch diagnosis with neural reconstruction
Bo-Xuan Ge
We investigate whether gravitational waveforms from massive boson-star mergers can be used to diagnose the underlying merger outcome. Using an existing numerical-relativity catalog…
Timing-Window Mechanism for Chain-Like Transients in Collisions of Radially Excited Boson Stars
Bo-Xuan Ge
We show that chain-like transients in head-on collisions of radially excited boson stars are controlled by the binary collision time, not by radial excitation alone. For selected \…
Hair is complicated: Gravitational waves from stable and unstable boson-star mergers
Bo-Xuan Ge, Eugene A. Lim, Ulrich Sperhake +5
We explore the gravitational-wave emission from head-on collisions of equal-mass solitonic boson-star binaries from simulations spanning a two-dimensional parameter space, consisti…
