Geometric entanglement in the Laughlin wave function
New Journal of Physics, 2017 We study numerically the geometric entanglement in the Laughlin wave function, which is of great importance in condensed matter physics. The Slater determinant having the largest overlap with the Laughlin wave function is constructed by an iterative ...

Slow-Goldstone mode generated by order from quantum disorder and its experimental detection
Journal of High Energy Physics, 2021 The order from quantum disorders (OFQD) phenomenon is well-known and ubiquitous in particle physics and frustrated magnetic systems. Typically, OFQD transfers a spurious Goldstone mode into a pseudo-Goldstone mode with a tiny gap.

Network comparison via encoding, decoding, and causality
Physical Review Research, 2023 Quantifying the relations (e.g., similarity) between complex networks paves the way for studying the latent information shared across networks. However, fundamental relation metrics are not well-defined between networks.

Dynamical changes of the polar cap potential structure: an information theory approach [PDF]
Nonlinear Processes in Geophysics, 2011 Some features, such as vortex structures often observed through a wide spread of spatial scales, suggest that ionospheric convection is turbulent and complex in nature.

Developing the tube theory for polymer knots
Physical Review Research, 2020 Entanglements make polymers fundamentally different from other molecules and thus are a major theme in polymer physics research. Interchain entanglements have been extensively investigated in past decades, while intrachain entanglements, often appearing ...

Nuclear Physics B, 2017 We investigate holographic phase transitions with dark matter sector in the AdS soliton background away from the probe limit. In cases of weak backreaction, we find that the larger coupling parameter α makes the gap of condensation shallower and the ...

Scientific ReportsThe porphyrazine structure, known for its high chemical and thermal stability, has become a significant focus in materials science, chemical reactivity, functionalization, and drug design. By utilizing the new Zagreb-type indices to analyze the chemical structure of porphyrazine, we can gather more information about their bonding and connecting ...

Entanglement entropy as a portal to the physics of quantum spin liquids [PDF]
, 2013 Quantum spin liquids (QSLs) are phases of interacting spins that do not order even at the absolute zero temperature, making it impossible to characterize them by a local order parameter.

Undecidability of the Spectral Gap in One Dimension
Physical Review X, 2020 The spectral gap problem—determining whether the energy spectrum of a system has an energy gap above ground state, or if there is a continuous range of low-energy excitations—pervades quantum many-body physics.

Anyon quantum dimensions from an arbitrary ground state wave function
Nature CommunicationsRealizing topological orders and topological quantum computation is a central task of modern physics. An important but notoriously hard question in this endeavor is how to diagnose topological orders that lack conventional order parameters.
