Article Synopsis
- This study aimed to investigate the relationship between cochlin tomoprotein testing (CTP), MRI findings, and hearing balance functions in patients experiencing sudden hearing loss.
- Eight patients with sudden hearing loss and possible vertigo or tinnitus were examined using CTP testing through middle ear samples and various MRI techniques.
- Results showed that while all patients exhibited non-specific contrast enhancement in the affected ear on MRI, only some had positive CTP tests indicating a potential perilymphatic fistula, but no MRI signals specifically indicated this condition.
Relaxation dynamics of complex many-body quantum systems trapped into metastable states is a very active field of research from both the theoretical and experimental point of view with implications in a wide array of topics from macroscopic quantum tunnelling and nucleosynthesis to non-equilibrium superconductivity and energy-efficient memory devices. In this work, we investigate quantum domain reconfiguration dynamics in the electronic superlattice of a quantum material using time-resolved scanning tunneling microscopy and unveil a crossover from temperature to noisy quantum fluctuation dominated dynamics. The process is modeled using a programmable superconducting quantum annealer in which qubit interconnections correspond directly to the microscopic interactions between electrons in the quantum material.

An exceptional example is the low-temperature metallic state of the layered dichalcogenide 1T-TaS in which electronic order is frozen after external excitation. Here we visualize the microscopic dynamics of injected charges in the metastable state using a multiple-tip scanning tunnelling microscope.

- Metastable phases are being explored for their potential to enhance the functionality of complex materials, especially those induced by light, which can exhibit unique properties that change rapidly.
- The research focuses on the ultrafast dynamics of a hidden quantum state in the material 1-TaS, using advanced spectroscopy techniques to understand how these phases form when light is applied.
- The findings indicate a nonthermal transition driven by a collective excitation, showcasing the ability to control the efficiency of this phase transition, which has promising implications for future electronic and photonic devices.
Mirror symmetry plays a major role in determining the properties of matter and is of particular interest in condensed many-body systems undergoing symmetry breaking transitions under non-equilibrium conditions. Typically, in the aftermath of such transitions, one of the two possible broken symmetry states is emergent. However, synthetic systems and those formed under non-equilibrium conditions may exhibit metastable states comprising of both left (L) and right (R) handed symmetry.
