Circuit Complexity in Z2 EEFT

Kiran Adhikari et al.

Summary: Motivated by recent studies, this research explores the computation of circuit complexity in Z2 Even Effective Field Theories (Z2 EEFTs) in the context of weakly interacting scalar field theory. The complexity of a massive free field theory with higher-order Wilsonian operators is calculated, considering both the simple case of two oscillators and the general case of N oscillators. Geometric approach and parameterization techniques are used to compute the complexity, taking into account the contribution of higher-order operators and the dependency on other parameters.

Quantum Hotspots: Mean Fields, Open EFTs, Nonlocality and Decoherence Near Black Holes

C. P. Burgess et al.

Summary: This study uses a solvable model to test the effectiveness of open EFT techniques and mean-field methods in describing black hole behavior. Open EFT techniques calculate the evolution of the field state, while mean-field methods generate nonlocal effective Hamiltonians. By applying these methods to a solvable system, their domains of applicability are identified and compared to traditional perturbative tools.

Discord and decoherence

Jerome Martin et al.

Summary: This paper investigates the impact of decoherence on quantum discord and finds that the evolution of quantum discord is influenced by the competition between the growth of squeezing amplitude and the decrease of state purity. A general parametrization is introduced to describe the partition of the system into subsystems, and these considerations are applied to study the classical properties of large-scale structures in the universe arising from quantum fluctuations.

Indirect detection of Cosmological Constant from interacting open quantum system

Subhashish Banerjee et al.

Summary: The study focuses on the indirect detection of the Cosmological Constant using spectroscopic shifts in an open quantum system of weakly interacting spins in the de Sitter background. The results show that the spectroscopic shifts, caused by the Casimir Polder interaction, play a crucial role in predicting a very tiny value of the Cosmological Constant in the static patch of de Sitter space, consistent with the observed value from the Planck measurements of the cosmic microwave background (CMB) anisotropies.

Real-space Bell inequalities in de Sitter

Llorenc Espinosa-Portales et al.

Summary: This study constructs Bell operators for quantum fields in real space and computes their expectation values for Gaussian states in terms of field power spectra. Applying the formalism to a scalar field in de-Sitter space-time, it is found that Bell inequalities are not violated in real space despite the generation of entangled particles on large scales. This is attributed to the implicit tracing over the field configurations at other locations, leading to effective decoherence and the erasure of quantum features.

C${\cal C}$osmological K${\cal K}$rylov C${\cal C}$omplexity

Kiran Adhikari et al.

Summary: In this paper, the Krylov complexity (K) of the de Sitter space is studied using the two mode squeezed state formalism in the presence of an effective sound speed. The explicit behavior of Krylov complexity (K) and Lancoz coefficients (bn) with respect to the conformal time scale and scale factor are obtained. The results suggest that the universe acts like a chaotic system during this period and that Krylov complexity (K) is related to the volume.

Summary: This paper investigates the application of four-mode squeezed states in the cosmological context, focusing on the weakly coupled two scalar field model in the planar patch of the de Sitter space. By constructing the formalism of four-mode squeezed states and obtaining the coupled differential equations for time evolution, interesting dynamics with physical implications are observed and explored.

Benchmarking the cosmological master equations

Thomas Colas et al.

Summary: Master equations are commonly used in cosmology to model the effect of additional degrees of freedom on a given system. This study applies the master-equation program to a solvable model and finds that it exhibits spurious terms depending on initial conditions. However, when these terms are removed, the master equation accurately reproduces the characteristics of the system.

Power spectrum in stochastic inflation

Kenta Ando et al.

Summary: This study calculates the power spectrum of curvature perturbations in stochastic inflation and investigates how quantum diffusion at small scales affects large-scale perturbations observed in the cosmic microwave background. The research shows that even if there is separation between small and large scales, quantum diffusion near the end of inflation can distort the classical relationship between field values and wavenumbers, leading to significant effects. This demonstrates that measurements of the cosmic microwave background can provide explicit constraints on the entire inflationary potential down to the end of inflation.

The Cosmological OTOC: A New Proposal for Quantifying Auto-Correlated Random Non-Chaotic Primordial Fluctuations

Sayantan Choudhury

Summary: In this paper, a computational method is demonstrated to quantify two different types of cosmological auto-correlated OTO functions during the dominative phase of non-equilibrium features in primordial cosmology. It is found that there are significantly distinguishable non-chaotic, but random, behaviors in the OTO auto-correlations, which were not previously identified in this type of study. Additionally, the classical limiting behavior of these auto-correlated OTOC functions matches the large-time limiting behavior of the auto-correlations in the super-horizon regime of cosmological scalar mode fluctuation.

Summary: In this paper, the techniques of parameter estimation theory and the concept of Quantum Metrology are applied to investigate the role of certain physical quantities in the open quantum dynamics of a two entangled qubit system. It is found that Quantum Metrology plays a superior role in improving the precision and accuracy of parameter estimation compared to classical parameter estimation theory. The paper also presents a new avenue in Quantum Metrology which surpasses classical parameter estimation.

Real-space entanglement of quantum fields

Jerome Martin et al.

Summary: This study introduces a new method for analytically determining the entanglement entropy between configurations of a quantum field at two distinct spatial locations, utilizing a bipartite, continuous Gaussian system. The method allows for deriving explicit formulas solely in terms of the Fourier-space power spectra of the field. This contrasts with previous studies relying on numerical considerations and leads to the first analytical derivation of results such as the decay of mutual information at large distances.

Kiran Adhikari et al.

Summary: This article investigates the connection between quantum circuit complexity and entanglement entropy in the black hole gas framework using the two-mode squeezed states formalism, analyzing the behavior of these quantities in three different spatial dimensions and observing significant differences in their evolution with respect to the scale factor. It also studies the relationship between equilibrium temperature, rate of change of complexity with scale factor, and entanglement entropy, finding that the equilibrium temperature depends quartically on entanglement entropy regardless of spatial dimension.
