Anomaly inflow, accidental symmetry, and spontaneous symmetry breaking

open access: yesJournal of High Energy Physics, 2020
We consider the 6d (1,0) SCFT on a stack of N M5-branes probing a ℂ2/ℤ2 singularity. In particular, we study its compactifications to four dimensions on a smooth genus-g Riemann surface with non-trivial flavor flux, yielding a family of 4d CFTs.

Breaking strong symmetries in dissipative quantum systems: Bosonic atoms coupled to a cavity

open access: yesPhysical Review Research, 2022
In dissipative quantum systems, strong symmetries can lead to the existence of conservation laws and multiple steady states. In this Letter we investigate a strong symmetry for bosonic atoms coupled to an optical cavity, an experimentally relevant system,

Anomaly constraint on massless QCD and the role of Skyrmions in chiral symmetry breaking [PDF]

open access: yesJournal of High Energy Physics, 2018
A bstractWe discuss consequences of the ’t Hooft anomaly matching condition for Quantum Chromodynamics (QCD) with massless fundamental quarks. We derive the new discrete ’t Hooft anomaly of massless QCD for generic numbers of color Nc and flavor Nf , and

Symmetry, Symmetry Breaking and Topology [PDF]

open access: yesSymmetry, 2010
The ground state of a system with symmetry can be described by a group G. This symmetry group G can be discrete or continuous. Thus for a crystal G is a finite group while for the vacuum state of a grand unified theory G is a continuous Lie group. The ground state symmetry described by G can change spontaneously from G to one of its subgroups H as the ...

Shape Memory Polymer‐Based Hook‐and‐Loop Fastener for Robust Bonding and on‐Demand Easy Separation

open access: yesAdvanced Engineering Materials, EarlyView.
A 3D shape memory polymer‐based hook‐and‐loop fastener, fabricated using projection microstereolithography and molding, offers tunable bonding strength through temperature control. When heated from 25 to 70 °C, the fastener softens and deforms easily, reducing bonding strength by 20‐fold for on‐demand easy separation.

The universe of symmetry breaking tasks [PDF]

open access: yesProceedings of the 30th annual ACM SIGACT-SIGOPS symposium on Principles of distributed computing, 2011
Processes in a concurrent system need to coordinate using a shared memory or a message-passing subsystem in order to solve agreement tasks such as, for example, consensus or set agreement. However, often coordination is needed to “break the symmetry” of processes that are initially in the same state, for example, to get exclusive access to a shared ...

Influence of Temperature on Scratch and Wear Properties of Technical Thermoplastics: Implications for Material Selection

open access: yesAdvanced Engineering Materials, EarlyView.
The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of
