Condensed concepts

This post concerns a basic but bold claim about the effects of a protein or solvent environment on chemical structure and reactivity. I am n...

I am skeptical of the grand and speculative claims of "quantum biology".  There is a nice paper in PNAS which systematically cons...

I am currently in Telluride for a meeting on Quantum effects in condensed phase systems . Two years ago I attended a similar meeting and in ...

Yesterday, Matthew Woolley gave an interesting Quantum science seminar at UQ about some of his recent work on Photon assisted tunnelling wi...

Tomorrow I am giving a talk at the Condensed Phase Dynamics meeting in Telluride. The slides are here . It is largely based on two papers w...

Last night I was stranded at Denver airport en route to the bi-annual Condensed phase dynamics meeting at the Telluride Science Research Ce...

It is always fascinating to me when one can experience some scientific concept in everyday life. I particularly like it when one can see thi...

Today I am giving a seminar in the Theoretical Physics Department of the Stefan Institute. The abstract is below. The slides are here . The ...

Tomorrow I am giving a seminar, "Essential state models for fluorescent protein chromophores and methine dyes," in the Chemistry d...

At the workshop a couple of talks have brought home to me two important organising principles for understanding and describing quantum eff...

Previously, I asked the question : are there any condensed phase systems in chemistry where quantum effects [e.g. tunneling, interference, e...

I am looking forward to attending a workshop on Quantum effects in condensed phase systems  at the Telluride Science Research Centre in July...

A key question about excited state dynamics in a solvent is the relative importance of the solvent polarity and the viscosity. This is exam...

What determines the excited state lifetime of a chromophore in a solvent? What are the relative importance of the polarity of the solvent [...

For the excited state dynamics of a specific chromophore in a solvent what are the essential degrees of freedom (electron...

T his week I am in Colorado at the  Telluride Science Research Center  for the workshop on Condensed Phase Dynamics.  Many of my favourite t...

Last two days I have read through a nice paper  Modeling the Nonradiative Decay Rate of Electronically Excited Thioflavin T by Yuval Erez, ...

How do quantum states in organic molecules couple to their environment (e.g., a solvent and/or protein)? Is the dynamics of excited states ...
