Spectroscopy of Quantum Phase Slips for Qubit Control

Published:Dec 30, 2025 22:35
1 min read
ArXiv

Analysis

This paper explores the use of spectroscopy to understand and control quantum phase slips in parametrically driven oscillators, which are promising for next-generation qubits. The key is visualizing real-time instantons, which govern phase-slip events and limit qubit coherence. The research suggests a new method for efficient qubit control by analyzing the system's response to AC perturbations.
Reference

“The spectrum of the system's response -- captured by the so-called logarithmic susceptibility (LS) -- enables a direct observation of characteristic features of real-time instantons.”

Instanton Homology and Fibered Knots: 2-Torsion and Alexander Polynomial

Published:Dec 30, 2025 13:14
1 min read
ArXiv

Analysis

This paper investigates the properties of instanton homology, a powerful tool in 3-manifold topology, focusing on its behavior in the presence of fibered knots. The main result establishes the existence of 2-torsion in the instanton homology of fibered knots (excluding a specific case), providing new insights into the structure of these objects. The paper also connects instanton homology to the Alexander polynomial and Heegaard Floer theory, highlighting its relevance to other areas of knot theory and 3-manifold topology. The technical approach involves sutured instanton theory, allowing for comparisons between different coefficient fields.
Reference

“The paper proves that the unreduced singular instanton homology has 2-torsion for any null-homologous fibered knot (except for a specific case) and provides a formula for calculating it.”

5D AGT Conjecture for Circular Quivers Explored

Published:Dec 29, 2025 21:36
1 min read
ArXiv

Analysis

This paper investigates the AGT correspondence, a relationship between conformal field theory and gauge theory, specifically in the context of 5-dimensional circular quiver gauge theories. It extends existing approaches using free-field formalism and integral representations to analyze both generic and degenerate conformal blocks on elliptic surfaces. The key contribution is the verification of equivalence between these conformal blocks and instanton partition functions and defect partition functions (Shiraishi functions) in the 5D gauge theory. This work provides a new perspective on deriving equations for Shiraishi functions.
Reference

“The paper checks equivalence with instanton partition function of a 5d circular quiver gauge theory...and with partition function of a defect in the same theory, also known as the Shiraishi function.”

Resurgence Analysis of Euler-Heisenberg Lagrangian in QED

Published:Dec 28, 2025 04:37
1 min read
ArXiv

Analysis

This paper provides a comprehensive resurgent analysis of the Euler-Heisenberg Lagrangian in both scalar and spinor quantum electrodynamics (QED) for the most general constant background field configuration. It's significant because it extends the understanding of non-perturbative physics and strong-field phenomena beyond the simpler single-field cases, revealing a richer structure in the Borel plane and providing a robust analytic framework for exploring these complex systems. The use of resurgent techniques allows for the reconstruction of non-perturbative information from perturbative data, which is crucial for understanding phenomena like Schwinger pair production.
Reference

“The paper derives explicit large-order asymptotic formulas for the weak-field coefficients, revealing a nontrivial interplay between alternating and non-alternating factorial growth, governed by distinct structures associated with electric and magnetic contributions.”
