Sum-of-squares compilation of matrix-model dynamics for NISQ and fault-tolerant hardware
The SU$(N)$ matrix-model potential $V=-\tfrac{g^2}{4}\sum_{I,J}Tr[X_I,X_J]^2$, the interaction of the BFSS/BMN family, whose thermal large-$N$ states are dual to black holes, is diagonal in the…How I Learned to Stop Worrying and Love the Redfield Equation: Completely-Positive Resummation of Non-Markovian Dynamics
The Redfield equation with time-dependent coefficients (or TCL2 equation) gives one of the simplest perturbative descriptions of open quantum system dynamics derived from a microscopic theory.Exact Recovery for Non-Abelian Surface Codes
We study exact recovery for non-Abelian topological surface codes based on the quantum double $D(G)$ of any finite group $G$.Comment on ''Chiral electromagnetic surface waves on Chern-Simons interfaces'' Phys.Rev.D114(2026)L051903 and on arXiv:2606.12513 by N. Kaloper
We demonstrate that Maxwell electrodynamics interacting with a planar Chern-Simons interface does not have plane wave solutions localized on the interface.Realizing Braided Fusion 2-Categories as (3+1)D Mixed-State Topological Orders
We construct large families of mixed-state topological orders in (3+1)D, including intrinsically mixed-state topological orders.Time-dependent integrable quantum field theories with dynamical boundaries
We present a method for constructing time-dependent integrable chiral quantum field theories on a finite spatial interval from the scattering and reflection data of an autonomous integrable model.On Information Propagation in Krylov Subspaces
Krylov subspace methods provide an efficient tool for modeling any quantum initial value problem as a one dimensional chain.Foundational puzzles on quantum universality: From Wigner's friend to black holes
Despite its remarkable empirical success and predictive power, quantum theory is riddled with mysteries.Complexity study of the Hartle-Hawking state in JT gravity
The Wigner function, in general, takes on negative values, and the amount of negativity in the Wigner function gives an operationally meaningful measure of the complexity of simulating the quantum…Vacuum entanglement in a time-dependent electric field
We analyze the correlations of the vacuum state of a charged scalar field by constructing localized observables in two disjoint regions.On-shell renormalization of sine-Gordon by the quantum inverse scattering method
In the quantum inverse scattering method, the sine-Gordon model is solved on a lattice, and its continuum and infinite-volume limits become uniform only after the length of the box is rescaled.Coherent Release Fronts in Krylov Chains and Thermal AdS$_2$ Response
We study coherent release from a finite serial Krylov sector into an exact conformal tail with asymptotically linear Lanczos coefficients.A No-Go Theorem for Order-Two Clifford Electric-Magnetic Duality
Electromagnetic duality in the toric code has order two at the level of anyon types and acts as a Hadamard-type logical transformation on the encoded quantum information.Unitary Schur Sampling of Qudits via Random SWAP Tests: Hunt for Antisymmetry
Schur sampling is a fundamental primitive for extracting permutation-invariant information from many-body quantum systems and has broad applications in quantum information science.A Semiclassical Entanglement Wedge in Double-Scaled SYK
We study the entanglement structure of partially entangled thermal states in double-scaled SYK , allowing flavor degrees of freedom carried by matter insertions to be in an arbitrary mixed state.Entanglement Requires Fluctuations at Conformal Interfaces
We conjecture that the universal logarithmic coefficient for capacity of entanglement $c_{\mathrm{cap}}$ is bounded below by the corresponding entropy coefficient $c_{\mathrm{eff}}$ at conformal…Relative entropy of entanglement and tripartite minimal surface
We propose a holographic dual of the relative entropy of entanglement for a boundary tripartition $A:B:C$.Chiral quantum chaos around exponentially many zero modes in the quantum breakdown model
The quantum breakdown model is a model of randomly interacting fermions, motivated by the physics of dielectric breakdown.Pauli instability in arbitrary states: detecting magic in physical correlators
Measures of non-stabilizerness (``magic'') of a quantum evolution quantify how hard it is to simulate on a classical computer.How AI Agents Discover Scientific Equations: From Hydrotope Rediscovery to New Water-Wave Amplitudes
We study how AI agents discover and validate scientific formulas using a controlled case study of the hydrotope, a recently discovered geometric formula that combines the different polynomial pieces…
