Journal of High Energy Physics, 2019 Perturbative calculations of the effective potential evaluated at a broken minimum, V min, are plagued by difficulties. It is hard to get a finite and gauge invariant result for V min.

Scaling‐Up of Structural Superlubricity: Challenges and Opportunities
Advanced Functional Materials, EarlyView.At increasing length‐scales, structural superlubricity (SSL) faces challenges from physical and chemical energy dissipation pathways. This study reviews recent experimental and theoretical progress on these challenges facing the scaling‐up of SSL, as well as perspectives on future directions for realizing and manipulating macroscale superlubricity ...

Stability and absence of a tower of states in ferrimagnets
Physical Review Research, 2020 Antiferromagnets and ferromagnets are archetypes of the two distinct (type-A and type-B) ways of spontaneously breaking a continuous symmetry. Although type-B Nambu-Goldstone modes arise in various systems, the ferromagnet was considered pathological due

Symmetry breaking by bifundamentals [PDF]
Physical Review D, 2018 We derive all possible symmetry breaking patterns for all possible Higgs fields that can occur in intersecting brane models: bi-fundamentals and rank-2 tensors. This is a field-theoretic problem that was already partially solved in 1973 by Ling-Fong Li. In that paper the solution was given for rank-2 tensors of orthogonal and unitary group, and U(N x U(

Advanced Functional Materials, EarlyView.This study examines the surface characteristics of AlInP (001), crucial for advanced solar cells and photoelectrochemical devices. Using theoretical modeling and experiments, it identifies how phosphorus‐rich and indium‐rich surfaces create mid‐gap states that pin the Fermi level and influence ultrafast electron dynamics.

Diversity of left-right symmetry breaking strategy in animals [version 1; peer review: 2 approved]
F1000Research, 2020 Left-right (L-R) asymmetry of visceral organs in animals is established during embryonic development via a stepwise process. While some steps are conserved, different strategies are employed among animals for initiating the breaking of body symmetry.

Flexible Leaf‐Like Fuel Cell From Plasmonic Janus Nanosheet
Advanced Functional Materials, EarlyView.A flexible leaf‐like fuel cell is fabricated by conductive gold nanowire sponge‐supported plasmonic Janus nanosheet, which can generate a power of 8.93 mW cm⁻2 with less than 10% performance deterioration even being bent or twisted. Further assembly in a tree‐like layout demonstrates omnidirectional light harvesting capability and wind resistance ...

Analysis and Geometry in Metric Spaces, 2016 We give an example of a smooth surface of revolution for which all circles about the origin are strictly stable for fixed area but small isoperimetric regions are nearly round discs away from the origin.

Scalar dark matter search from the extended νTHDM
Journal of High Energy Physics, 2018 We consider a neutrino Two Higgs Doublet Model (νTHDM) in which neutrinos obtain naturally small Dirac masses from the soft symmetry breaking of a global U(1) X symmetry.
