Band Gap Renormalization at Different Symmetry Points in Perovskites
Using ultrafast broad-band transient absorption (TA) spectroscopy of photoexcited MAPbBr3 thin films with probe continua in the visible and the mid- to deep-ultraviolet (UV) ranges, we capture the ultrafast renormalization at the fundamental gap at the R s ...
Amer Chemical Soc2024'Fraternal-twin' ferroelectricity: competing polar states in hydrogen-doped samarium nickelate from first principles
In ferroelectric switching, an applied electric field switches the system between two polar symmetry-equivalent states. In this work, we use first-principles calculations to explore the polar states of hydrogen-doped samarium nickelate (SNO) at a concentra ...
Iop Publishing Ltd2024Mean value theorems for collections of lattices with a prescribed group of symmetries
Euclidean lattices are mathematical objects of increasing interest in the fields of cryptography and error-correcting codes. This doctoral thesis is a study on high-dimensional lattices with the motivation to understand how efficient they are in terms of b ...
EPFL2024Holography and localization of information in quantum gravity
Kyriakos Papadodimas, Alexandre Mathieu Frédéric Belin
Within the AdS/CFT correspondence, we identify a class of CFT operators which represent diff-invariant and approximately local observables in the gravitational dual. Provided that the bulk state breaks all asymptotic symmetries, we show that these operator ...
Springer2024Critical line of the triangular Ising antiferromagnet in a field from a C3-symmetric corner transfer matrix algorithm
Frédéric Mila, Samuel Louis Nyckees, Afonso Dos Santos Rufino, Jeanne Colbois
The corner transfer matrix renormalization group (CTMRG) algorithm has been extensively used to investigate both classical and quantum two-dimensional (2D) lattice models. The convergence of the algorithm can strongly vary from model to model depending on ...
College Pk2023Dynamic nuclear polarisation of 1H in Gd-doped In(OH)3
David Lyndon Emsley, Michael Allan Hope, Yuxuan Zhang, Amrit Venkatesh
Dynamic nuclear polarisation (DNP) of solids doped with high-spin metal ions, such as Gd3+, is a useful strategy to enhance the nuclear magnetic resonance (NMR) sensitivity for these samples. Spin diffusion can relay polarisation throughout a sample, which ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2023Polarization-Controlled Chromo-Encryption
Olivier Martin, Hsiang-Chu Wang
The response of simple plasmonic nanorods to polarized illumination is studied in detail. Depending on the orientation of that polarization with respect to the symmetry axes of the nanostructure, a chiral response can occur, which can be analyzed through a ...
WILEY-V C H VERLAG GMBH2023Interactions of Cavitation Bubbles with Deformable Interfaces
Cavitation is a topic that has long been of interest due to the large and growing range of applications associated with it. This is mainly because the collapse of cavitation bubbles releases a considerable amount of energy into the surrounding environment. ...
EPFL2023Non-Gaussian superradiant transition via three-body ultrastrong coupling
We introduce a class of quantum optical Hamiltonians characterized by three-body couplings and propose a circuit-QED scheme based on state-of-the-art technology that implements the considered model. Unlike two-body light-matter interactions, this three-bod ...
AMER PHYSICAL SOC2023Berry curvature dipole generation and helicity-to-spin conversion at symmetry-mismatched heterointerfaces
The Berry curvature dipole (BCD) is a key parameter that describes the geometric nature of energy bands in solids. It defines the dipole-like distribution of Berry curvature in the band structure and plays a key role in emergent nonlinear phenomena. The th ...
