A Trade-Off Between Path Entanglement and Quantum Sensitivity

Posted by dbos MIT

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Benjamin Lou, Hudson A. Loughlin, Nergis Mavalvala, , | Summary: Entanglement often increases quantum measurement schemes’ sensitivity. However, we find that in precision measurements with zero-mean Gaussian states, such as squeezed states, entanglement between different paths degrades measurement sensitivity. We prove an inverse relationship between entanglement entropy […]

The Higgs-Amplitude mode in the optical conductivity in the presence of a supercurrent: Gauge invariant forumulation

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Rufus Boyack, K. Levin, , | Summary: Observing the amplitude-Higgs mode in superconductors has been a central challenge in condensed matter physics. Unlike the phase mode in the electromagnetic (EM) response, the amplitude mode is not needed to satisfy gauge invariance. Indeed, it couples to […]

Multi-sample non-negative spatial factorization

Posted by dbos Hopkins

Kavli Affiliate: Loyal Goff | Authors: Yi Wang, Kyla Woyshner, Chaichontat Sriworarat, Genevieve Stein-O’Brien, Loyal A Goff and Kasper D Hansen | Summary: Analyzing multi-sample spatial transcriptomics data requires accounting for biological variation. We present multi-sample non-negative spatial factorization (mNSF), an alignment-free framework extending single-sample spatial factorization (NSF) to multi-sample datasets. mNSF incorporates sample-specific spatial […]

A New Moiré Platform Based on M-Point Twisting

Posted by dbos Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Dumitru Călugăru, Yi Jiang, Haoyu Hu, Hanqi Pi, Jiabin Yu | Summary: We introduce a new class of moir’e systems and materials based on monolayers with triangular lattices and low-energy states at the M points of the Brillouin zone. These M-point moir’e materials are fundamentally distinct from […]

A giant planet transiting a 3-Myr protostar with a misaligned disk

Posted by dbos MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Madyson G. Barber, Andrew W. Mann, Andrew Vanderburg, Daniel Krolikowski, Adam Kraus | Summary: Astronomers have found more than a dozen planets transiting 10-40 million year old stars, but even younger transiting planets have remained elusive. A possible reason for the lack of such discoveries is that […]

Intrinsic Quantum Mpemba Effect in Markovian Systems and Quantum Circuits

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Dongheng Qian, Huan Wang, Jing Wang, , | Summary: The quantum Mpemba effect (QME) describes the counterintuitive phenomenon in which a system farther from equilibrium reaches steady state faster than one closer to equilibrium. However, ambiguity in defining a suitable distance measure between quantum states has led […]

Seeking the nearest neutron stars using a new local electron density map

Posted by dbos Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Joseph Bramante, Katherine Mack, Nirmal Raj, Lijing Shao, Narayani Tyagi | Summary: Neutron stars provide a compelling testing ground for gravity, nuclear dynamics, and physics beyond the Standard Model, and so it will be useful to locate the neutron stars nearest to Earth. To that end, we […]

Topological finite size effect in one-dimensional chiral symmetric systems

Posted by dbos Delft

Kavli Affiliate: Eliska Greplova | First 5 Authors: Guliuxin Jin, D. O. Oriekhov, Lukas Johannes Splitthoff, Eliska Greplova, | Summary: Topological phases of matter have been widely studied for their robustness against impurities and disorder. The broad applicability of topological materials relies on the reliable transition from idealized, mathematically perfect models to finite, real-world implementations. […]
