Holomorphic field theories and higher algebra

Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

The fate of (phantom) dark energy universe with string curvature corrections

, 2005
We study the evolution of (phantom) dark energy universe by taking into account the higher-order string corrections to Einstein-Hilbert action with a fixed dilaton.

Efficient Simulation of Open Quantum Systems on NISQ Trapped‐Ion Hardware

Advanced Quantum Technologies, Volume 8, Issue 9, September 2025.
Open quantum systems exhibit rich dynamics that can be simulated efficiently on quantum computers, allowing us to learn more about their behavior. This work applies a new method to simulate certain open quantum systems on noisy trapped‐ion quantum hardware.

Effective potential for revolving D-branes

Journal of High Energy Physics, 2019
We quantize an open string stretched between D0-branes revolving around each other. The worldsheet theory is analyzed in a rotating coordinate system in which the worldsheet fields obey simple boundary conditions, but instead the worldsheet Lagrangian ...

Gravitating Semilocal strings

, 2009
We discuss the properties of semilocal strings minimally coupled to gravity. Semilocal strings are solutions of the bosonic sector of the Standard Model in the limit $\sin^2\theta_W=1$ (where $\theta_W$ is the Weinberg angle) and correspond to embedded ...

Quantum Algorithms for Quantum Molecular Systems: A Survey

WIREs Computational Molecular Science, Volume 15, Issue 3, May/June 2025.
Quantum algorithms for quantum molecular systems: from molecular encoding, to Hamiltonian simulation, static properties, and quantum advantage. ABSTRACT Solving quantum molecular systems presents a significant challenge for classical computation. The advent of early fault‐tolerant quantum computing devices offers a promising avenue to address these ...

An excursion into the string spectrum

Journal of High Energy Physics, 2023
We propose a covariant technique to excavate physical bosonic string states by entire trajectories rather than individually. The approach is based on Howe duality: the string’s spacetime Lorentz algebra commutes with a certain inductive limit of sp ...

Dirichlet Boundary Conditions in Generalized Liouville Theory toward a QCD String

, 2000
We consider bosonic noncritical strings as QCD strings and we present a basic strategy to construct them in the context of Liouville theory. We show that Dirichlet boundary conditions play important roles in generalized Liouville theory.

Dark Dimension With (Little) Strings Attached

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

On the Uniqueness of String Theory

, 1993
We show that bosonic strings may be viewed as a particular class of vacua for N=1 superstrings, and N=1 superstrings may be viewed as a particular class of vacua for N=2 strings.
