Towards a Minergie Standard for tropical climates
Jean-Louis Scartezzini, Franco Vigliotti, Claude-Alain Roulet, Fouad Aabid
The Swiss Minergie®-standard is, by the number of labelled buildings (> 20'000) one of the most successful building energy labels in the world. It is obviously a strong incentive for designing comfortable, low energy buildings. This standard is now valid f ...
EPFL2011Ultrafast structural dynamics in electronically excited solid neon. I. Real-time probing of the electronic bubble formation
Majed Chergui, Franco Vigliotti, Luigi Bonacina
The dynamics of electron bubble formation upon excitation of the A(3ss) Rydberg orbital of NO in solid Ne was studied by conventional spectroscopy and fs pump-probe spectroscopy. The fs pump pulse initiates the formation of a bubble by the expansion of the ...
2003Ultrafast structural dynamics in electronically excited solid neon. II. Molecular-dynamics simulations of the electronic bubble formation
Majed Chergui, Franco Vigliotti
Mol.-dynamics simulations of structural relaxation in electronically excited NO-doped solid neon are presented. The NO impurity is excited to its lowest A (3ss) Rydberg state, inducing a rearrangement of the surrounding medium in the form of a bubble, due ...
2003Structural dynamics in quantum solids. I. Steady-state spectroscopy of the electronic bubble in solid hydrogens
Majed Chergui, Franco Vigliotti
The structural changes due to formation of electronic bubbles in solid D2 are studied by fluorescence, fluorescence-excitation, and fluorescence-depletion spectroscopy of the lowest Rydberg state, A 2S+(3ss), of the NO impurity. The A X band is strongly bl ...
2002Structural dynamics in quantum solids. II. Real-time probing of the electronic bubble formation in solid hydrogens
Majed Chergui, Franco Vigliotti, Luigi Bonacina
The ultrafast dynamics of electronic bubble formation upon excitation of the A(3ss) Rydberg state of NO trapped in solid H2 and D2 was studied by femtosecond pump-probe spectroscopy. The evolution of the spherical bubble is followed in real time by a probe ...
2002Ultrafast expansion and vibrational coherences of electronic 'Bubbles' in solid neon
Majed Chergui, Franco Vigliotti
The dynamics of electron bubble formation upon excitation of the A(3ss) Rydberg orbital of NO in solid Ne was studied by femtosecond pump-probe spectroscopy. The authors observe an ultrafast expansion of the bubble, followed by a vibrational recurrence in ...
2002Ultrafast Structural dynamics in solid hydrogens: A model for condensed phase quantum systems
Majed Chergui, Franco Vigliotti, Luigi Bonacina
Structural dynamics in solid hydrogens is impulsively triggered by femtosecond excitation of the lowest Rydberg state of the NO impurity. The resulting charge redistribution induces a local radial deformation of the medium ("bubble" formation) around the ...
2002Impurity Rydberg states as probes of local dynamics in the condensed phase
Majed Chergui, Franco Vigliotti
We report on structural dynamics in simple van der Waals solids (Ar, Ne, and H2), as driven by the excitation of an impurity (NO) Rydberg state. The resulting charge redistribution induces a local radial deformation of the medium ("bubble" formation). Th ...
2001Femtosecond dynamics of electronic 'bubbles' in solid argon: viewing the inertial response and the bath coherences
Majed Chergui, Franco Vigliotti, Marcia Portella Oberli
The dynamics of non-polar electronic solvation has been studied on a model system consisting of NO-doped solid Ar. Excitation of the lowest Rydberg state A(3ss) of NO leads to formation of an electronic 'bubble', which has been studied by femtosecond pump- ...
2000Rydberg states in the condensed phase studied by fluorescence depletion spectroscopy
Majed Chergui, Franco Vigliotti
Higher Rydberg states of NO trapped in rare gas matrixes were studied by inducing Rydberg-Rydberg transitions from the lowest A2S+ (3ss) Rydberg state and detecting its fluorescence depletion. This technique unravels Rydberg states, which cannot be accesse ...
