Deformed Bubbles and Lorentz Invariance in Vacuum Decay
, 2012 Recently, questions have been raised about the role of Lorentz invariance in false vacuum decay. It has been argued that infinities may arise in an integration over Lorentz-boosted final states. This suggestion motivates a Minkowski-space analysis of the

Room Temperature Synthesis and Photopatterning of Mesoporous Titanium Dioxide Thin Films
Advanced Materials Technologies, EarlyView.A nanofabrication strategy combining deep‐UV photolithography with block copolymer self‐assembly enables direct patterning and mineralization of mesoporous TiO2 thin films at room temperature. Photocatalytic titanium oxo‐clusters promote polymer degradation under UV irradiation, enabling multiscale control over porosity, film thickness, and lateral ...

Deformed Special Relativity and Deformed Symmetries in a Canonical Framework
, 2007 In this paper we have studied the nature of kinematical and dynamical laws in $\kappa $-Minkowski spacetime from a new perspective: the canonical phase space approach. We discuss a particular form of $\kappa$-Minkowski phase space algebra that yields the

Advanced Optical Materials, EarlyView.Optical and plasmonic properties of TiN and Ti(O)N thin films were tuned at the synthesis stage by modulating the oxygen pressure during room‐temperature pulsed laser deposition. Ti(O)N thin films exhibiting a highly metallic and peculiar double‐epsilon‐near‐zero (DENZ) behavior were produced.

Quantum twist-deformed D = 4 phase spaces with spin sector and Hopf algebroid structures
Physics Letters B, 2019 We consider the generalized (10+10)-dimensional D=4 quantum phase spaces containing translational and Lorentz spin sectors associated with the dual pair of twist-quantized Poincare Hopf algebra H and quantum Poincare Hopf group Gˆ.

Chiral QED in Terms of Chiral Boson with a Generalized Fadeevian Regularization
, 2003 Chiral QED with a generalized Fadeevian regularization is considered. Imposing a chiral constraint a gauged version of Floranini-Jackiw lagrangian is constructed.

Journal of Approximation Theory, 1996 Let \(G\) be a connected Lie group and \(X_1, \dots, X_k\) a Hörmander system of left invariant vector fields on \(G\), i.e. vector fields which, together with their successive brackets, generate the tangent space at every point. Let \(\Delta = \sum X^2_j\) be the corresponding Laplace operator on \(G\).

Advanced Optical Materials, EarlyView.Thermal expansion and the thermo‐optic effect in solids are closely coupled, reflecting concurrent changes in mass density and polarizability. Using echo‐resolved THz spectroscopy, we simultaneously determine sub‐micrometer thermal expansion and complex refractive index changes of MgO and Al2O3 from 10–325 K. The analysis yields both the coefficient of
