Coherent Phonon Catalysts: Lattice Vibrations Drive a Photoinduced Phase Transition in a Molecular Crystal

The atomic motions that make up phonons and molecular vibrations in molecular crystals influence their photophysical and electronic properties including polaron formation, carrier mobility, and phase transitions. Expand abstract.

Sharp interface limit of a multi-phase transitions model under nonisothermal conditions

A vectorial Modica--Mortola functional is considered and the convergence to a sharp interface model is studied. Expand abstract.

Information geometry of scaling expansions of non-exponentially growing confifiguration spaces

This allows us to characterize transitions between statistical manifolds corresponding to different families of probability distributions. Expand abstract.

Anisotropic character of the metal-to-metal transition in Pr4Ni$_3$O$_{10}$

As a member of the Ruddlesden-Popper Ln$_{n+1}$Ni$_n$O$_{3n+1}$ series rare-earth-nickelates, the Pr4Ni$_3$O$_{10}$ consists of infinite quasi-two-dimensional perovskite-like Ni-O based layers. Expand abstract.

Upper limit on first-order electroweak phase transition strength

Using Boedeker-Moore criterion for bubble wall runaway, within the context of an extension of the standard model of particle physics with a real gauge-single scalar field, we show that a non runaway transition requirement puts an upper bound on the strength of the first-order phase transition.

Layer-Magnetization-Tuned Topological Phases in Mn$_2$Bi$_2$Te$_5$ Films

The interplay between band topology and magnetic order could generate a variety of time-reversal-breaking gapped topological phases with exotic topological quantization phenomena, such as quantum anomalous Hall (QAH) insulators and axion insulators (AxI). Expand abstract.

Transport signatures of topological phases in double nanowires probed by spin-polarized STM

We study a double-nanowire setup proximity coupled to an $s$-wave superconductor and search for the bulk signatures of the topological phase transition that can be observed experimentally, for example, with an STM tip. Expand abstract.

On the diffusive-mean field limit for weakly interacting diffusions exhibiting phase transitions

In particular, we show that these two limits do not commute if the mean field system constrained to the torus undergoes a phase transition, that is to say if it admits more than one steady state. Expand abstract.

Intelligence, physics and information -- the tradeoff between accuracy and simplicity in machine learning

In the information bottleneck, we theoretically show that these phase transitions are predictable and reveal structure in the relationships between the data, the model, the learned representation and the loss landscape. Expand abstract.
