Rigorous Lower Bounds for Atomic and Ionic Ground-State Energies
We establish a new iterative method for computing rigorous lower bounds for the ground-state energies of all atoms and ions.Path integral control in the complex plane
Path integral control is a stochastic optimal control framework that computes optimal policies as weighted averages over state trajectories.Stochastic quantization and Osterwalder-Schrader axioms for quantum field theory models
This PhD thesis constructs the $P(Φ)_2$ Euclidean quantum field theory on $\mathscr{S}'(\mathbb{R}^2)$.Semiclassical dynamics of higher-order squeezing: self-adjoint extensions and coherent returns
Higher-order squeezing Hamiltonians have several self-adjoint realizations, while their classical trajectories reach infinity in finite time.When is a bosonic operator a Hamiltonian?
Hermitian polynomials in the quadrature operators $x$ and $p$ are the basic ingredients of continuous-variable quantum information, and increasingly exotic ones are now routinely engineered in…Admissible Subspaces for the Collective Haar Twirl: Schur-Weyl Classification and Heredity under Tensor-Factor Reduction
Quantum private broadcasting (\textsf{QPB}) asks whether a quantum message can be encrypted once, broadcast to several recipients, and decrypted locally while the joint ciphertext reveals no…Krylov geometry and optimal recovery under uncertain coherent noise
Recovery from a coherent rotation with an unobserved angle depends on both the encoding and what calibration reveals about the noise.Induced Bell-CHSH observables in the Fewster-Verch measurement scheme
The Summers-Werner theorem shows that the vacuum of a relativistic quantum field theory violates the Bell-CHSH inequality maximally on complementary wedges, but it is an existence statement: it…V-Representability Beyond Singular Times in Time-Dependent Density Functional Theory: The Hubbard Dimer Case
We study the global $V$-representability problem in time-dependent density functional theory (TDDFT) for the two-particle Hubbard dimer model in the spin-singlet sector.Helstrom geometry with time-dependent spectral calibration
In a recent work we introduced a finite scalar-qubit-scalar spectral triple whose Connes distance reproduces the Bloch-ball trace metric up to a factor $2/Λ$, where $Λ^2=μ_L^2+μ_R^2$ for isotropic…Can Spontaneous Time-Translation Symmetry Breaking Be Quantized Without Explicit Branches?
Can classically branched dynamics associated with spontaneous time-translation-symmetry breaking be quantized without explicitly retaining the branches of the Hamiltonian?Performing a Quantum Subroutine Using Cluster States
Quantum subroutines, like their classical counterparts, serve as essential components of larger algorithms.An Invitation to Algebraic Methods in Quantum Theory
In this paper, we present various well-studied examples of quantum systems, and discuss how they might be analysed algebraically.Discrete WKB approach to density profiles in inhomogeneous two-band free-fermion chains
We extend the discrete WKB method to one-dimensional bipartite tight-binding chains of free fermions with slowly varying hopping amplitudes and on-site potentials.Ideal interaction dynamics of defects and background fields in condensed matter
While defect dynamics in condensed matter systems is widely studied and several methods are available to track the defect position over time, the formulation of dynamical models for the coupled…A New Non-Affine Family in the Karlsson-Szollosi Intersection
We show that $K_6^{(2)} \cap X_6^{(2)} = D_6^{(1)} \cup C_6^{(1)}$ up to standard Hadamard equivalence, where $C_6^{(1)}$ is a new non-affine one-parameter family of complex Hadamard matrices.A sharp gradient-corrected Lieb--Thirring inequality in one dimension with applications to density functional theory
We first prove a sharp Lieb-Thirring inequality with semi-classical constant and gradient correction in one dimension.Size-independent Logarithmic Sobolev Inequalities for Quantum Gibbs Samplers
We propose a new method for proving $L^2$ and modified logarithmic Sobolev inequalities with constants independent of system size for quantum Gibbs samplers whose Lindblad generators satisfy…Some minimal characteristics and flat trajectories of a system in the N-body problem
For the classical model of a system of N particles with interaction (the N-body problem) we consider some spatial problems of nonlinear programming for finding conditional minima and local extrema…On exact solutions to three-dimensional Yukawa lattice model and BCC to FCC phase transitions
We determine the global minimizers of the three-dimensional Yukawa lattice energy at every fixed density.
