Robust measurement of wave function topology on NISQ quantum computers
Xiao Xiao, J. K. Freericks, A. F. Kemper
Topological quantum phases of quantum materials are defined through their topological invariants. These topological invariants are quantities that characterize the global geometric…
Lagrangian space consistency relation for large scale structure
Bart Horn, Lam Hui, Xiao Xiao
Consistency relations, which relate the squeezed limit of an (N+1)-point correlation function to an N-point function, are non-perturbative symmetry statements that hold even if the…
Holographic Representation of Higher Spin Gauge Fields
Debajyoti Sarkar, Xiao Xiao
Extending the results of \cite{Heem}, \cite{KLRS} on the holographic representation of local gauge field operators in anti de Sitter space, here we construct the bulk operators for…
Note on Adiabatic Modes and Ward Identities In A Closed Universe
Xiao Xiao
As statements regarding the soft limit of cosmological correlation functions, consistency relations are known to exist in any flat FRW universe. In this letter we explore the possi…
Soft-Pion Theorems for Large Scale Structure
Bart Horn, Lam Hui, Xiao Xiao
Consistency relations -- which relate an N-point function to a squeezed (N+1)-point function -- are useful in large scale structure (LSS) because of their non-perturbative nature:…
Holographic Representation of Local Operators In De Sitter Space
Xiao Xiao
Assuming the existence of the dS/CFT correspondence, we construct local scalar fields with in de Sitter space by smearing over conformal field th…
Tumbling through a landscape: Evidence of instabilities in high-dimensional moduli spaces
Brian Greene, David Kagan, Ali Masoumi +3
We argue that a generic instability afflicts vacua that arise in theories whose moduli space has large dimension. Specifically, by studying theories with multiple scalar fields we…
Decay process of quantum open system at finite-temperature
X. Xiao, Y. B. Gao
Starting from the formal solution to the Heisenberg equation, we revisit an universal model for a quantum open system with a harmonic oscillator linearly coupled to a boson bath. T…
Bubble Nucleation of Spatial Vector Fields
Ali Masoumi, Xiao Xiao, I-Sheng Yang
We study domain-walls and bubble nucleation in a non-relativistic vector field theory with different longitudinal and transverse speeds of sound. We describe analytical and numeric…
Moving Stable Solitons in Galileon Theory
Ali Masoumi, Xiao Xiao
Despite the no-go theorem [5] which rules out static stable solitons in Galileon theory, we propose a family of solitons that evade the theorem by traveling at the speed of light.…
