Advanced Energy Materials, EarlyView.We identify two decisive levers for SAM interfaces: molecular design (carboxylic acid‐based, phosphonic acid, other anchoring chemistries, and polymeric SAMs) and mixing routes (co‐assembly, in situ assembly, pre‐ and post‐treatment). Coordinated tuning of headgroups and assembly pathways optimises energy alignment and film formation, suppresses ...

Patterns of Spontaneous Chiral Symmetry Breaking
, 2001 It has been conjectured that spontaneous chiral symmetry breaking in strongly coupled vectorlike gauge theories falls into only three different classes, depending on the gauge group and the representations carried by the fermions.

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation
Advanced Intelligent Systems, EarlyView.Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Anomaly induced transport from symmetry breaking in holography
Journal of High Energy PhysicsWe study the transport properties of relativistic fluids induced by quantum anomalies in presence of explicit symmetry breaking. To this end we consider a holographic Einstein-Maxwell model in 5 dimensions with pure gauge and a mixed gauge-gravitational ...

Scars in Dirac fermion systems: the influence of an Aharonov–Bohm flux
New Journal of Physics, 2017 Time-reversal ( ${ \mathcal T }$ -) symmetry is fundamental to many physical processes. Typically, ${ \mathcal T }$ -breaking for microscopic processes requires the presence of magnetic field.

Study of QCD-like theories at nonzero temperatures and densities
, 2012 In this thesis I use effective models to investigate the properties of QCD-like theories at nonzero temperature and baryon chemical potential. First I construct a PNJL model using a lattice spin model with nearestneighbor interactions for the gauge ...

Continuous chiral symmetry breaking in a calculable regime [PDF]
, 2016 I will discuss work with M. Unsal on a semiclassically-calculable regime of 4D QCD, obtained by an adiabatic circle compactification, in which continuous chiral symmetry breaking can be studied systematically.Cherman, Aleksey. (2016).

Baryon and chiral symmetry breaking
, 2014 We briefly review the generalized Skyrmion model for the baryon recently suggested by us. It takes into account the tower of vector and axial mesons as well as the chiral symmetry breaking.

Restricting symmetry (rather than breaking it)
, 2019 The symmetry of a discrete structure can easily be altered (or in the case of maps, destroyed) by changing just a small part of it. But there are other contexts where a large degree of symmetry is desirable without achieving the maximum possible ...
