Disorder-Induced Order in Two-Component Bose-Einstein Condensates
Armand Niederberger, Thomas Schulte, Jan Wehr +3
We propose and analyze a general mechanism of disorder-induced order in two-component Bose-Einstein condensates, analogous to corresponding effects established for XY spin models.…
Disorder versus the Mermin-Wagner-Hohenberg effect: From classical spin systems to ultracold atomic gases
Jan Wehr, Armand Niederberger, Laurent Sanchez-Palencia +1
We propose a general mechanism of random-field-induced order (RFIO), in which long-range order is induced by a random field that breaks the continuous symmetry of the model. We par…
Photon-Number-Splitting versus Cloning Attacks in Practical Implementations of the Bennett-Brassard 1984 protocol for Quantum Cryptography
Armand Niederberger, Valerio Scarani, Nicolas Gisin
In practical quantum cryptography, the source sometimes produces multi-photon pulses, thus enabling the eavesdropper Eve to perform the powerful photon-number-splitting (PNS) attac…
