Quantum shape phase transitions from spherical to deformed for Bose-Fermi systems: the effect of the odd particle around the critical point

open access: yesEPJ Web of Conferences, 2014
Quantum phase transitions in odd-nuclei are investigated within the framework of the interacting boson-fermion model with a description based on the concept of intrinsic states.

Self-interacting dark matter and muon (g − 2) in a gauged U1Lμ−Lτ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ model

open access: yesJournal of High Energy Physics, 2018
We construct a self-interacting dark matter model that could simultaneously explain the observed muon anomalous magnetic moment. It is based on a gauged U1Lμ−Lτ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ extension of the standard model, where we ...

Combination of searches for invisible decays of the Higgs boson using 139 fb−1 of proton-proton collision data at s=13 TeV collected with the ATLAS experiment

open access: yesPhysics Letters B, 2023
Many extensions of the Standard Model predict the production of dark matter particles at the LHC. Sufficiently light dark matter particles may be produced in decays of the Higgs boson that would appear invisible to the detector.

Emergent Spin Supersolids in Frustrated Quantum Materials

open access: yesAdvanced Materials, EarlyView.
This review highlights developments in the study of spin super‐solids in frustrated quantum materials. Advanced experimental characterizations and computational studies enable a comprehensive understanding of the driving mechanisms of spin super‐solidity in various layered transition‐metal compounds, bridging materials, experiments, and theory aspects.

Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review

open access: yesAdvanced Science, EarlyView.
Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

The prolate-oblate shape phase transition in the interacting boson model

open access: yesEPJ Web of Conferences, 2013
The prolate-oblate shape phase transition in the the interacting boson model is revisited by adopting the transitional Hamiltonian with a linear dependence on the control parameter. The analysis of the shape phase transition in both the large-N limit and

Halide Perovskite: A Rich Source of Thermal Insulator

open access: yesAdvanced Science, EarlyView.
Halide perovskites exhibit ultralow thermal conductivity driven by intrinsic lattice softness and strong anharmonicity, falling below conventional defect‐engineering limits. Weak metavalent bonding, A‐site rattling, and dynamic octahedral tilting drive phonon scattering to the Ioffe–Regel limit, where wave‐like tunneling replaces particle‐like ...

Singlet extensions and W boson mass in light of the CDF II result

open access: yesPhysics Letters B, 2022
Recently, the CDF collaboration has reported the precise measurement of the W boson mass, MW=80433.5±9.4MeV, based on 8.8 fb−1 of s=1.96 TeV pp¯ collision data from the CDF II detector at the Fermilab Tevatron.

Comprehensive DFT Analysis of FeSi and RhSi: Structural Stability, Electronic Contrast and Transport‐Optical Responses

open access: yesAdvanced Physics Research, EarlyView.
This comprehensive density functional theory analysis investigates the structural, electronic, optical, mechanical, and thermoelectric properties of FeSi, c‐RhSi, and o‐RhSi. Results reveal distinct electronic and optical contrasts among the materials.
