Odds Estimation for Supermassive Black Hole Binaries in Local Core Galaxies
Supermassive black hole binaries (SMBHBs) are expected products of massive galaxy mergers, but identifying binaries in nearby galaxies remains challenging.Fate of Quantum Magic
Magic, a quantum resource distinct from entanglement, measures departure from states stabilized by products of Pauli operators.Atom as an Agent: Emergent Order by Collective Predictive Coding
What is the intrinsic reason of emergence of macroscopic order parameter out of microscopic systems?The Disordered Universe 2025: Open Effective Field Theories
Effective field theories (EFTs) offer a powerful method to unify diverse models under a small set of control parameters, allowing systematic expansions around well-established theories.Momentum-space entanglement and mutual information in Kaluza-Klein reduction
In theories with compact extra dimensions, the four-dimensional effective description is obtained by Kaluza-Klein reduction.Meet-in-the-Middle Compilation of the $[\mathrm{CNOT}]$ Class with Fibonacci Anyons
Compilation of two-qubit Fibonacci anyon gates is complicated by leakage ($\ell$) from the four-dimensional computational sector to the fifth state of the fusion space.Bargmann-invariant witness of the graviton commutator
We identify the phase of a Bargmann invariant of two matter-wave interferometers as a quantum gravity signature that cannot be reproduced by any branchwise-definite classical gravitational field.Multipartite dynamics beyond bipartite entanglement equilibration
Entanglement equilibration need not mark the end of quantum-information dynamics in quantum thermalization.Compositional Operational Rank, Smooth Realizability, and Dimensional Reduction
Higher-dimensional theories distinguish the dimensionality of a microscopic description from the number of directions accessible to a physical observer.AlgebrasTQD: Computing Algebras and Interfaces in Twisted Quantum Doubles
We present AlgebrasTQD, an open-source code written in GAP (Groups, Algorithms, and Programming), for computing condensable algebras and the corresponding topological boundaries and interfaces of…Analytic Bootstrap Solution for Quantum Mechanics on a Circle
We solve the Schrödinger equation for a particle in the circle with a quantum mechanical bootstrap method.An open EFT for dark matter searches with matter-wave interferometers
Matter-wave interferometers (MWIs) are a genuine quantum probe of dark matter (DM), being sensitive to DM-induced phase shifts and loss of contrast.Mesons, Confinement, and Complexity: A Krylov Space Perspective on the Long-Range Ising Chain
We investigate the interplay between confinement and Krylov complexity in the long-range transverse-field Ising chain, where power-law interactions $\sim 1/r^α$ generate an effective confining…Non-Hermitian Schwinger effect in an imaginary magnetic field
We investigate a non-Hermitian Schwinger effect by analyzing a one-loop effective Lagrangian of scalar and Dirac quantum electrodynamics (QED) in the presence of a real electric field and a parallel…Scaling and Renormalization in Neural Networks: An Effective Renormalization-Group Description of Grokking
Grokking is a delayed transition from memorization to generalization in deep neural networks (NNs).Quantum hydrodynamics from Nambu's unpublished fluid notes
We develop a quantum hydrodynamic theory based on Nambu's unpublished note \emph{A New Look at Fluid Dynamics}.Side jump and anomalous Lorentz transformation of a coherent Dirac wave packet
Spin-orbit coupling makes the mean position of a spinning particle transform anomalously under a Lorentz boost, with an additional shift known as a side jump.Estimation of covariance matrix for Stokes-like measurement under phase-space deformation
We investigate the signatures of phase-space noncommutativity in an anisotropic oscillator and propose an optomechanical protocol to experimentally characterize it through Stokes-like measurements…Krylov geometry and optimal recovery under uncertain coherent noise
Recovery from a coherent rotation with an unobserved angle depends on both the encoding and what calibration reveals about the noise.Induced Bell-CHSH observables in the Fewster-Verch measurement scheme
The Summers-Werner theorem shows that the vacuum of a relativistic quantum field theory violates the Bell-CHSH inequality maximally on complementary wedges, but it is an existence statement: it…
