A potential exomoon from the predicted planet obliquity of Pictoris b
Michael Poon, Hanno Rein, Dang Pham
Planet obliquity is the alignment or misalignment of a planet spin axis relative to its orbit normal. In a multiplanet system, this obliquity is a valuable signature of planet form…
Simulating Vibrational Dynamics on Bosonic Quantum Devices
Shreyas Malpathak, Sangeeth Das Kallullathil, Artur F. Izmaylov
Bosonic quantum devices, which utilize harmonic oscillator modes to encode information, are emerging as a promising alternative to conventional qubit-based quantum devices, especia…
Efficient Strategies for Reducing Sampling Error in Quantum Krylov Subspace Diagonalization
Gwonhak Lee, Seonghoon Choi, Joonsuk Huh +1
Within the realm of early fault-tolerant quantum computing (EFTQC), quantum Krylov subspace diagonalization (QKSD) has emerged as a promising quantum algorithm for the approximate…
Data Collectives as a means to Improve Accountability, Combat Surveillance and Reduce Inequalities
Jane Hsieh, Angie Zhang, Seyun Kim +7
Platform-based laborers face unprecedented challenges and working conditions that result from algorithmic opacity, insufficient data transparency, and unclear policies and regulati…
Observation uncertainty effects on the precision of interior planetary parameters
Mykhaylo Plotnykov, Diana Valencia
Determining compositions of low-mass exoplanets is essential in understanding their origins. The certainty by which masses and radius are measured affects our ability to discern pl…
TRACE: a code for Time-Reversible Astrophysical Close Encounters
Tiger Lu, David M. Hernandez, Hanno Rein
We present TRACE, an almost time-reversible hybrid integrator for the planetary N-body problem. Like hybrid symplectic integrators, TRACE can resolve close encounters between parti…
