Invertible subalgebras for chiral semion topological order
Chiral topological order is incompatible with strictly two-dimensional local commuting-projector Hamiltonians on finite-dimensional tensor-product Hilbert spaces.Conformalized Physics-Informed Weak Regression for Parameter Estimation in Epidemic Models
Compartment models of infectious diseases are often linear in coefficients that are physical parameters or products or ratios of them.Beyond the lemon: Spectra of random Lindblad operators with a Hamiltonian component
Generators of continuous-time quantum Markovian evolution, known as Lindblad operators, play a key role in the theory of open quantum systems.From isolated singular wells to exact Bloch bands: the trigonometric Pöschl-Teller lattice
An exactly solvable lattice with periodic inverse-square singularities exhibits two physically distinct mechanisms of spectral-gap closure.Probe Signatures of Quantum Chaos with Quantum Sensing
The spectral form factor (SFF), which is the Fourier transform of the two-point spectral correlation, is a fundamental diagnostics of quantum chaos.Classical and Quantum Information Measures Characterizing Convertibility: An Axiomatic Approach
In this PhD thesis, we take an axiomatic approach to studying multivariate divergences, which are measures of the information content of a tuple of classical or quantum states.Nested polynomial algebras and the exact spectrum of a three-dimensional two-spin oscillator
We construct representations of the symmetry algebra and derive the exact spectrum of a three-dimensional oscillator with two spin-$\tfrac12$ degrees of freedom.Finite-time quantum equilibration from local correlations
An isolated quantum system evolves reversibly, yet a small subsystem can lose nearly all information about its initial state.Closed-form construction of exceptional points in a two-parametric PT-symmetric large-matrix model
Stable bound states living on a discrete one-dimensional N-point lattice are assumed generated by a certain two-parametric PT symmetric potential $V=V(A,B)$.Entanglement Sudden Death in Gapped Ground States
Spatial sudden death of entanglement refers to the disappearance of quantum correlations between subsystems after a certain distance called the entanglement length.Norm properties of quantum uniformity measures
We prove that for $k=4$ the quantum uniformity measures are norms, whereas for every $k\geq5$ the triangle inequality fails.Small perturbations of the $2d$ classical Heisenberg model
Polyakov predicted in 1975 ([Pol75) that the spin $O(3)$-model (or classical Heisenberg model) should have exponential decay of correlations at all positive temperatures on $\mathbb{Z}^2$.Non-Stationary Quantum Systems Associated with Stationary Scattering in One Dimension
Stationary scattering admits a dynamical formulation in which the scattering data are extracted from the evolution operator for an effective non-stationary and non-unitary quantum system.An optimization problem for $δ'$ leaky stars
We consider singular Schrödinger operators with an attractive $δ'$ interaction of strength $β$ supported by a star graph and prove that the ground-state eigenvalue is uniquely maximized by stars of…On the OpenAI proof that Landau-Siegel zeros do not exist
A recent manuscript of OpenAI asserts that Landau-Siegel zeros do not exist.Harmonic Reduction of Spin-Coupled Grover Walks on Hypercubes via Quantum Bernoulli Noises
We consider spin-coupled Grover walks on hypercubes within the framework of quantum Bernoulli noises (QBN).Classical Communication Helps Single-Shot Quantum Compression
Free classical communication can yield an unbounded single-shot saving in quantum compression, even though it leaves the asymptotic rate of an i.i.d. source unchanged.DisCo Algebra: Why Disintegration and Combination Are Not Inverses
We present DisCo algebra---a compositional framework for joint probability built from a symmetric cooperad (disintegration) and a symmetric operad (combination) on the bare family…The Rényi area law conjecture is false below $α=1$ in high dimensions
Area laws express the expectation that entanglement in gapped quantum ground states scales with a boundary rather than a volume.Adjoint Transfer and Order-Lifting Dichotomies for 2 x 2 Matrices over Prime-Power Rings
For an odd prime p, we study the change in matrix order under lifting from Z/p^k Z to Z/p^(k+1) Z. The first variation of the order defect is an affine translate of a cyclic adjoint transfer on…
