Multi-Time States in Quantum and Operational Probabilistic Theories: An Axiomatic Framework
Quantum states over time were introduced, in part, to extend Bayesian probability to quantum theory and have since found applications across diverse areas, ranging from quantum causality and…A thermally and perturbatively stable classical spin model in two dimensions
We show that the 2D classical spin model constructed in arXiv:2605.10943 hosts many metastable states at non-zero temperature which are stable to arbitrary Hamiltonian perturbations, providing the…A simpler proof that there are no Landau--Siegel zeros
This paper simplifies the recent OpenAI proof that there are no Landau--Siegel zeros.Failure of direct finiteness for group algebras in every odd characteristic
For every odd prime $p$, we construct a finitely presented group $G_p$ and elements $a,b,c\in\mathbb{F}_p[G_p]$ such that $ab=1$, $ac=0$, and $c\ne0$.A note on the A.C. spectrum of limit-periodic Jacobi matrices
We show that limit-periodic Jacobi matrices in the weak exponential class $EC(η)$ have purely absolutely continuous spectral type when $η$ is sufficiently large, depending only on the…Coherent-State Integrals Beyond the Domain of Operator Products
Inserting a resolution of the identity between two operators turns a matrix element of their product into a phase-space integral.Computational compressive imaging reconstruction with a simulated-annealing-based Ising solver
Computational compressive imaging, such as single-pixel imaging and lensless imaging, is a promising imaging technique, enabling the reconstruction of objects from under-sampled measurements through…Acoustic scattering from quantum dynamics
Scattering of sound waves propagating in a compressible fluid is linked to the quantum dynamics generated by a class of non-Hermitian Hamiltonian operators.Multi-Instantons and Exact-WKB Stokes Jumps in Multi-Well Quantum Mechanics
We study the relation between the exact-WKB Delabaere--Dillinger--Pham Stokes jumps and the multi-instanton expansion of a one-dimensional potential with $N$ equal-depth minima.Exact analytical spectra of an effective field-modified radial Schrödinger equation by the Nikiforov--Uvarov method
We revisit the effective radial Schrödinger equation for a charged spinless particle in collinear static electric and magnetic fields that was formulated in our earlier work within the tridiagonal…Quantized six-vertex realizations of frustration graphs
A recent graph-theoretic criterion for a Hamiltonian to exhibit a free-parafermion spectrum is that its frustration graph be an indifference graph.Degeneracy graph determinants and higher-dimensional Young diagrams
Kemp and Ramgoolam proposed a basis of monomials for a commutative semisimple algebra with generators \(C_1,\ldots, C_L\), constructed from a degeneracy graph which records how the eigenspaces of \(…Infinite magic and the emergence of the continuum
Which features of a quantum state are needed for a relativistic quantum field theory to emerge from a lattice system?Kaplansky's conjectures fail for torsion-free hyperbolic groups in positive characteristic
Do Kaplansky's group-ring conjectures hold for torsion-free word-hyperbolic groups?Sampling from the Sherrington-Kirkpatrick Model up to Criticality
We prove that the simulated annealing algorithm efficiently samples from the Sherrington-Kirkpatrick model at inverse temperature $β< 1$ to an arbitrary inverse polynomial accuracy in total variation.How many switches does two-Hamiltonian universality require?
Any pair of sufficiently generic Hamiltonians on $\mathbb{C}^d$ generates the full unitary group, i.e., any $W\in U(d)$ can be synthesized to arbitrary precision by alternating between the two…Dynamics of low energy wave packets in the one-dimensional quantum Heisenberg ferromagnet
Spin wave theory plays a central role in the analysis of low-energy properties of the quantum ferromagnetic Heisenberg model.Dynamical BEC formation and vanishing entropy for trapped bosons in non-relativistic QED via nonlinear resonance cascades
The dynamical formation of a complete Bose-Einstein condensate and the asymptotic purification of trapped bosons coupled to a quantized radiation field are rigorously established.Beyond Gaussian Entanglement: Practical Criteria for Polynomially Excited Quantum States
Polynomial excitations consisting of creation and annihilation operators are studied.On the coincidence of discrete and continuous definitions of Entanglement of Formation
It is proved that every Borel ensemble of pure states on a separable bipartite Hilbert space with finite average entanglement admits a countable ensemble with the same barycenter and arbitrarily…
