Shedding light on the star formation rate-halo accretion rate connection and halo quenching mechanism via DECODE, the Discrete statistical sEmi-empiriCal mODEl

Posted by klaurent February 10, 2025Peking

Kavli Affiliate: Yingjie Peng | Summary:Aims: The relative roles of the physical mechanisms involved in quenching galaxy star formation are still unclear. We tackle this fundamental problem with our cosmological semi-empirical model DECODE (Discrete statistical sEmi-empiriCal mODEl), designed to predict galaxy stellar mass assembly histories, from minimal input assumptions. Methods: Specifically, in this work the […]

Nonrenormalization Theorem for $cal N=(4,4)$ Interface Entropy

Posted by klaurent February 10, 2025Tokyo

Kavli Affiliate: Hirosi Ooguri | Summary:We derive a formula for the half-BPS interface entropy between any pair of $cal N=(4,4)$ theories on the same conformal manifold. This generalizes the diastasis formula derived in arXiv:1311.2202 for $cal N=(2,2)$ theories, which is restricted to the conformal submanifolds generated by either chiral or twisted chiral multiples of $cal […]

Scalar field dark energy models: Current and forecast constraints

Posted by klaurent February 10, 2025Chicago

Kavli Affiliate: Joshua Frieman | Summary:Recent results from Type Ia supernovae (SNe Ia) and baryon acoustic oscillations (BAO), in combination with cosmic microwave background (CMB) measurements, have focused renewed attention on dark energy models with a time-varying equation-of-state parameter, $w(z)$. In this paper, we describe the simplest, physically motivated models of evolving dark energy that […]

Bunch-Davies initial conditions and non-perturbative inflationary dynamics in Numerical Relativity

Posted by klaurent February 10, 2025Cambridge

Kavli Affiliate: E. P. S. Shellard| First 5 Authors: Yoann L. Launay, Yoann L. Launay, , , | Summary:We show that it is possible to simulate realistic inhomogeneities during cosmological inflation with high precision using Numerical Relativity. Stochastic initial conditions are set in line with the Bunch-Davies vacuum and satisfy the Hamiltonian and Momentum constraints […]

Heisenberg-limited calibration of entangling gates with robust phase estimation

Posted by klaurent February 10, 2025Berkeley

Kavli Affiliate: Irfan Siddiqi | Summary:The calibration of high-quality two-qubit entangling gates is an essential component in engineering large-scale, fault-tolerant quantum computers. However, many standard calibration techniques are based on randomized circuits that are only quadratically sensitive to calibration errors. As a result, these approaches are inefficient, requiring many experimental shots to achieve acceptable performance. […]

Quantum Non-Local Nonstabilizerness

Posted by dbos February 10, 2025Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Dongheng Qian, Jing Wang, , , | Summary: Quantum entanglement and quantum nonstabilizerness are fundamental resources that characterize distinct aspects of a quantum state: entanglement reflects non-local correlations, while nonstabilizerness quantifies the deviation from stabilizer states. A quantum state becomes a valuable resource for applications like universal […]
