Spontaneous decompactification [PDF]
Physical Review D, 2004 Positive vacuum energy together with extra dimensions of space imply that our four-dimensional Universe is unstable, generically to decompactification of the extra dimensions. Either quantum tunneling or thermal fluctuations carry one past a barrier into

On spontaneous scalarization [PDF]
Physical Review D, 1998 We study in the physical frame the phenomenon of spontaneous scalarization that occurs in scalar-tensor theories of gravity for compact objects. We discuss the fact that the phenomenon occurs exactly in the regime where the Newtonian analysis indicates ...

Chemical Reviews, 2021 Spontaneous deracemizations is a challenging, multidisciplinary subject in current chirality research. In the absence of any chiral inductors, an achiral substance or a racemic composition is driven into an enantioenriched or even homochiral state through a selective energy input, e.g., chemical potential, photoirradiation, mechanical grinding ...

Mechanisms of Spontaneous Current Generation in an Inhomogeneous d-Wave Superconductor [PDF]
, 1994 A boundary between two d-wave superconductors or an s-wave and a d-wave superconductor generally breaks time-reversal symmetry and can generate spontaneous currents due to proximity effect.

Spontaneous acroangiodermatitis
Indian Journal of Dermatology, 2015 Acroangiodermatitis is a rare self-limited angioproliferative lesion which can be associated with congenital vascular malformations or acquired venous insufficiency. Despite of its benign character, differential diagnosis of this lesion is very important because it closely resembles Kaposi sarcoma.

Spontaneous pneumothorax [PDF]
Multidisciplinary Respiratory Medicine, 2011 Pneumothorax is defined as the presence of air in the pleural space due to: a) communication be- tween alveolar spaces and pleura; b) direct or indi- rect exchange of air between the atmosphere and the pleural space; or c) the presence of gas produc- ing organisms in the pleural space.

Spontaneous thought and vulnerability to mood disorders : the dark side of the wandering mind [PDF]
, 2016 There is increasing interest in spontaneous thought, namely task-unrelated or rest-related mental activity. Spontaneous thought is an umbrella term for processes like mind-wandering, involuntary autobiographical memory, and daydreaming, with evidence ...

Spontaneous CP Violation [PDF]
, 1998 In this talk I begin with some general discussion of the history of CP violation, then move on to aspects of the aspon model including the production of new particles at LHC, implications for B decay, generalized Cabibbo mixing and a reevaluation of kaon

Journal of Economic Perspectives, 1989 In a fishing village on the Yorkshire coast, there used to be an unwritten rule about the gathering of driftwood after a storm. Whoever was first onto a stretch of the shore after high tide was allowed to take whatever he wished without interference from later arrivals and to gather it into piles above the high-tide line. Provided he placed two stones

Spontaneous Magnon Decays [PDF]
, 2013 A theoretical overview of the phenomenon of spontaneous magnon decays in quantum antiferromagnets is presented. The intrinsic zero-temperature damping of magnons in quantum spin systems is a fascinating many-body effect, which has recently attracted ...
