Amplified Memory and Finite-Time Regularity in Driven Non-Hermitian Systems
We study the roles of broken spectra and exceptional points in finite-time driven non-Hermitian fermionic dynamics.Analytic detector responses and entanglement in constant-curvature spacetimes
We derive analytic response functions for Unruh--DeWitt detectors coupled to real, massless, conformally coupled scalar fields, to distinguish the effects of the field spectrum and global geometry…Onset of random-matrix statistics in the Yukawa-Sachdev-Ye-Kitaev model: Spectral correlations and Krylov complexity
The Yukawa-Sachdev-Ye-Kitaev (YSYK) model, a solvable model of non-Fermi liquids with a proposed cavity-QED realization, couples $N$ complex fermions to $M$ bosons of frequency $ω_0$ through random…Informational and algebraic renormalization group
Renormalization group (RG) is a core concept in physics from statistical mechanics to quantum field theory, yet its schemes differ widely between field theory and many-body physics.Disentangling the Toric Code
Commuting-projector Hamiltonians with integer spectrum such as the 1+1d Ising ferromagnet and the 2+1d toric code may be regarded as the generators of non-on-site $U(1)$ symmetries.Entanglement transitions in holographic conformal interfaces
We study entanglement transitions for pairs of disjoint intervals in two-dimensional holographic interface conformal field theories.Classical Root Systems Reveal Defect-Junction Data in Stabilizer Renyi Entropy
Universal information extracted from a critical quantum state depends on how the state is probed.Local Vacuum Entanglement through Most Entangled Modes
We find the shape of the modes containing most of the entanglement between two disjoint spherical regions in the vacuum of a free massless real scalar field in 1+3 Minkowski spacetime.Non-stabilizerness and entanglement in $(2+1)$-dimensional SU(2) lattice gauge theory using tensor networks
We study non-stabilizerness (magic) in the ground state of $(2+1)$-dimensional $\mathrm{SU}(2)$ Hamiltonian lattice gauge theory with matter, formulated in the dressed-site basis in the…Quantum Computing Solution of the Bethe-Salpeter Equation for Relativistic Scalar Bound States via Tensor-Network VQE
We present a gate-based quantum computing solution of the homogeneous Bethe-Salpeter equation (hBSE) for the bound state of two massive relativistic scalar particles interacting via…Unified spatiotemporal quantum states and spatiotemporal entanglement from Kirkwood-Dirac phase space
The notion of a spatiotemporal quantum state extends the conventional concept of a spatial quantum state to the spatiotemporal domain.Measuring correlations using local and nonlocal quenches
We present a theoretical proposal for measuring correlation functions in a quantum field system based on the use of quantum quenches.Nonlocal advantage of quantum coherence in tau-lepton pairs from electron--positron collisions
Quantum correlations have recently attracted significant attention in collider physics, with Nonlocal Advantage of Quantum Coherence (NAQC) representing the strongest form of quantum correlation…Operator-Level Quantum-Classical Correspondence in Relativistic Quantum Theory and Curved Spacetime
In a recent work \cite{Shaikh:2026nsi}, it was shown that for a non-relativistic particle, the operator equations of motion can be cast in the same differential form as Newton's equation of motion.The shape of quark flavors
We construct the Yukawa couplings of the quark sector as overlap integrals of Gaussian wave functions in extra spatial dimensions.Deep learning emergent spacetime from fermionic spectral functions in holography
We present a physics-informed machine learning framework based on Neural Ordinary Differential Equations that solves the holographic inverse problem: reconstructing the bulk spacetime and gauge…
