Say NO to Optimization: A Nonorthogonal Quantum Eigensolver
PRX Quantum, 2023 A balanced description of both static and dynamic correlations in electronic systems with nearly degenerate low-lying states presents a challenge for multiconfigurational methods on classical computers.

On the Three-point Function in Minimal Liouville Gravity [PDF]
, 2005 The problem of the structure constants of the operator product expansions in the minimal models of conformal field theory is revisited. We rederive these previously known constants and present them in the form particularly useful in the Liouville gravity

Localization in Nets of Standard Spaces [PDF]
, 2014 Starting from a real standard subspace of a Hilbert space and a representation of the translation group with natural properties, we construct and analyze for each endomorphism of this pair a local, translationally covariant net of standard subspaces, on ...

Existence of invariant curves for degenerate almost periodic reversible mappings
Discrete and Continuous Dynamical Systems. Series A, 2022 In this paper we are concerned with the existence of invariant curves for almost periodic reversible mappings with higher order degeneracy of the twist condition.

Comments on the quantum field theory of the Coulomb gas formalism
Journal of High Energy Physics, 2021 The holomorphic Coulomb gas formalism, as developed by Feigin-Fuchs, Dotsenko-Fateev and Felder, is a set of rules for computing minimal model observables using free field techniques. We attempt to derive and clarify these rules using standard techniques

On growth rate and contact homology [PDF]
, 2014 It is a conjecture of Colin and Honda that the number of Reeb periodic orbits of universally tight contact structures on hyperbolic manifolds grows exponentially with the period, and they speculate further that the growth rate of contact homology is ...

Existence of Invariant Curves for Degenerate Quasi-periodic Reversible Mappings
Taiwanese journal of mathematics, 2022 In this paper we are concerned with the existence of invariant curves of quasi-periodic reversible mappings with higher order degeneracy of the twist condition under the Brjuno–Rüssmann’s non-resonant condition.

On Katz's $(A,B)$-exponential sums [PDF]
, 2020 We deduce Katz's theorems for $(A,B)$-exponential sums over finite fields using $\ell$-adic cohomology and a theorem of Denef-Loeser, removing the hypothesis that $A+B$ is relatively prime to the characteristic $p$.

Path integral Monte Carlo simulation of degenerate electrons: Permutation-cycle properties. [PDF]
Journal of Chemical Physics, 2019 Being motivated by the surge of fermionic quantum Monte Carlo simulations at finite temperature, we present a detailed analysis of the permutation-cycle properties of path integral Monte Carlo (PIMC) simulations of degenerate electrons.

Applications of incidence bounds in point covering problems [PDF]
, 2016 In the Line Cover problem a set of n points is given and the task is to cover the points using either the minimum number of lines or at most k lines.
