Quasiprobability representations of quantum mechanics with minimal negativity [PDF]
Physical Review Letters, 2016 Quasiprobability representations, such as the Wigner function, play an important role in various research areas. The inevitable appearance of negativity in such representations is often regarded as a signature of nonclassicality, which has profound ...

Holographic entanglement negativity and replica symmetry breaking [PDF]
Journal of High Energy Physics, 2021 Since the work of Ryu and Takayanagi, deep connections between quantum entanglement and spacetime geometry have been revealed. The negative eigenvalues of the partial transpose of a bipartite density operator is a useful diagnostic of entanglement.

Symmetry decomposition of negativity of massless free fermions [PDF]
, 2021 We consider the problem of symmetry decomposition of the entanglement negativity in free fermionic systems. Rather than performing the standard partial transpose, we use the partial time-reversal transformation which naturally encodes the fermionic ...

Negativity drives online news consumption
Nature Human Behaviour, 2023 Online media is important for society in informing and shaping opinions, hence raising the question of what drives online news consumption. Here we analyse the causal effect of negative and emotional words on news consumption using a large online dataset

Entanglement Negativity at Measurement-Induced Criticality [PDF]
PRX Quantum, 2020 We propose entanglement negativity as a fine-grained probe of measurement-induced criticality. We motivate this proposal in stabilizer states, where for two disjoint subregions, comparing their "mutual negativity" and their mutual information leads to a ...

Blood Advances, 2020 The prognostic value of minimal residual disease (MRD) for progression-free survival (PFS) and overall survival (OS) was evaluated in a large cohort of patients with multiple myeloma (MM) using a systematic literature review and meta-analysis.

Entanglement Negativity Spectrum of Random Mixed States: A Diagrammatic Approach [PDF]
PRX Quantum, 2020 The entanglement properties of random pure states are relevant to a variety of problems ranging from chaotic quantum dynamics to black hole physics. The averaged bipartite entanglement entropy of such states admits a volume law and upon increasing the ...

Islands for entanglement negativity [PDF]
SciPost Physics, 2020 We advance two alternative proposals for the island contributions to the entanglement negativity of various pure and mixed state configurations in quantum field theories coupled to semiclassical gravity.

Making Sense of Mismatch Negativity
Frontiers in Psychiatry, 2020 Evoked potentials provide valuable insight into brain processes that are integral to our ability to interact effectively and efficiently in the world. The mismatch negativity (MMN) component of the evoked potential has proven highly informative on the ...

Pentapartite Entanglement Measures of GHZ and W-Class State in the Noninertial Frame
Entropy, 2022 We study both pentapartite GHZ and W-class states in the noninertial frame and explore their entanglement properties by carrying out the negativities including 1-4, 2-3, and 1-1 tangles, the whole entanglement measures such as algebraic and geometric ...
