In recent years it has become possible to produce gases of atoms at unimaginable temperatures close to absolute zero or zero degrees Kelvin, the lowest temperature allowed by the laws of physics. Oddly, this is often achieved by using lasers that cool the atoms to temperatures around 100 nanokelvin, a tiny fraction of a degree – there are in fact as many nanokelvin in one degree as there are seconds in a period of 30 years. Alas some elements are still difficult to cool in this way, mainly because of a lack of suitable lasers or the cooling process is compromised. Hydrogen is particularly difficult but fortunately we have potentially found a unique way of creating a very, very cold gas of hydrogen atoms. The trick is to actually use the lasers to cool something else, a tiny molecule consisting of two atoms, one of which is the hydrogen required. There are a number of hydrogen containing molecules that can be laser cooled, so the idea is to then gently remove the hydrogen atom from its partner using tweezers of light. Curiously, we have shown that the mass of the companion atom in the molecule influences the final temperature of the hydrogen atoms produced, with a heavier partner leading to a colder gas of hydrogen. Consequently, we wish to study heavy diatomic hydrides such as BaH and YbH.
One exciting application is the creation of a quantum gas of hydrogen atoms called a Bose-Einstein Condensate from the fragmentation of diatomic molecules that are themselves not cold enough to form such as gas. This would allow the creation of this unique phase of matter on demand with nanosecond precision, an ability not usually possible with phase changes. A particular focus will be the production of the heavier isotope deuterium by the fragmentation of BaD as such atoms have so far resisted all attempts to cajole them into a quantum gas by current means.
Happily, the technique could also be used to cool other light elements such as carbon, nitrogen and oxygen, essentially all the elements of life. Such a cold gas of hydrogen could have a number of applications, including testing whether the physical constants of the Universe are really constants after all and as a delicate probe of material surfaces, such as the components of electronic circuits.

Additional course costs
Depending on the programme of study, there may also be other extra costs which are not covered by tuition fees, which students will need to consider when planning their studies . Students can borrow books and access online learning resources from any Queen's library. If students wish to purchase recommended texts, rather than borrow them from the University Library, prices per text can range from £30 to £100. Students should also budget between £30 to £100 per year for photocopying, memory sticks and printing charges. Students may wish to consider purchasing an electronic device; costs will vary depending on the specification of the model chosen. There are also additional charges for graduation ceremonies, and library fines. In undertaking a research project students may incur costs associated with transport and/or materials, and there will also be additional costs for printing and binding the thesis. There may also be individually tailored research project expenses and students should consult directly with the School for further information.
Some research programmes incur an additional annual charge on top of the tuition fees, often referred to as a bench fee. Bench fees are charged when a programme (or a specific project) incurs extra costs such as those involved with specialist laboratory or field work. If you are required to pay bench fees they will be detailed on your offer letter. If you have any questions about Bench Fees these should be raised with your School at the application stage. Please note that, if you are being funded you will need to ensure your sponsor is aware of and has agreed to fund these additional costs before accepting your place.
