Gravitational-Wave Data Analysis with High-Precision Numerical Relativity Simulations of Boson Star mergers

Posted by klaurent Cambridge

Kavli Affiliate: Ulrich Sperhake | Summary:Gravitational-wave signals detected to date are commonly interpreted under the paradigm that they originate from pairs of black holes or neutron stars. Here, we explore the alternative scenario of boson-star signals being present in the data stream. We perform accurate and long ($sim 20$ orbits) numerical simulations of boson-star binaries […]

Quantum-enabled continuous microwave-to-optics frequency conversion

Posted by klaurent Caltech

Kavli Affiliate: Mohammad Mirhosseini | Summary:A quantum interface between microwave and optical photons is essential for entangling remote superconducting quantum processors. To preserve fragile quantum states, a transducer must operate efficiently while generating less than one photon of noise referred to its input. Here, we present a platform that meets these criteria, utilizing a combination […]

TDCOSMO. XVI. Measurement of the Hubble Constant from the Lensed Quasar WGD$,$2038$-$4008

Posted by klaurent Stanford

Kavli Affiliate: Philip Marshall | Summary:Time-delay cosmography is a powerful technique to constrain cosmological parameters, particularly the Hubble constant ($H_0$). The TDCOSMO collaboration is performing an ongoing analysis of lensed quasars to constrain cosmology using this method. In this work, we obtain constraints from the lensed quasar WGD 2038-4008 using new time-delay measurements and previous […]

Random Reed-Solomon Codes and Random Linear Codes are Locally Equivalent

Posted by klaurent Caltech

Kavli Affiliate: G. Ravichandran| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:We establish an equivalence between two important random ensembles of linear codes: random linear codes (RLCs) and random Reed-Solomon (RS) codes. Specifically, we show that these models exhibit identical behavior with respect to key combinatorial properties — such as list-decodability and list-recoverability — […]

Fermion-fermion interaction driven phase transitions in the rhombohedral trilayer graphene

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Qiao-Chu Zhang, Jing Wang, , , | Summary: The effects of short-range fermion-fermion interactions on the low-energy properties of the rhombohedral trilayer graphene are comprehensively investigated by virtue of the momentum-shell renormalization group method. We take into account all one-loop corrections and establish the energy-dependent coupled evolutions […]
