Research Assist­ant (Postdoc) (m/f/d)


full-time job
lim­ited to 2 years
Ent­gelt­gruppe 13 TV-L FU
Ref­er­ence code: TRR227_The­ory_2022

Working field:

The Trans­re­g­ional Col­lab­or­at­ive Research Cen­ter CRC/TRR 227 at Freie Uni­versität Ber­lin (lead­ing) and Mar­tin-Luther-Uni­versität Halle-Wit­ten­berg has just obtained fund­ing for a second period from 2022 to 2025. The CRC/TRR 227 research focuses at a fun­da­mental under­stand­ing of ultra­fast spin dynam­ics, thereby lay­ing the found­a­tions for spin-based inform­a­tion tech­no­logy that can be oper­ated at THz clock rates. Our goals are to gather and develop detailed know­ledge about spin dynam­ics and the con­com­it­ant coup­lings of elec­tron, phonon, and spin degrees of free­dom on ultra­fast time scales span­ning the range between 1 fs and 10 ps. Ulti­mately, this know­ledge will lead to new spin­tronic func­tion­al­it­ies and devices. In total, 17 sci­entific pro­jects headed by 28 prin­cipal invest­ig­at­ors team up their research activ­it­ies on ultra­fast dynam­ics of mag­netic order and ultra­fast spin cur­rents.

Job descrip­tion:
The postdoc­toral researcher is expec­ted to per­form the­or­et­ical invest­ig­a­tions as well as to do com­pu­ta­tion­ally-based mod­el­ling within the research area of the­or­et­ical con­densed mat­ter phys­ics, with a spe­cial focus on ultra­fast mag­net­ism, such as mod­el­ling of ultra­fast spin cur­rents, the­ory for light-induced dynam­ical pro­cesses, THz pulse emis­sion, ultra­fast spec­tro­scopy and the­ory for cur­rent-induced spin dynam­ics.
The research tasks include the devel­op­ment of the­or­et­ical mod­els and com­puter sim­u­la­tion pro­grams to model ultra­fast non-equi­lib­rium spin cur­rents and high-fre­quency spin dynam­ics in anti­fer­ro­mag­netic and topo­lo­gical spin­tronic mater­i­als, as well as to sim­u­late THz emis­sion from these mater­i­als. Vari­ous com­puter pro­grams (like Dens­ity-Func­tional The­ory and spin dynam­ics codes) will be used in the mod­el­ling of non-equi­lib­rium spin cur­rents and induced spin dynam­ics.
The pro­ject is part of the CRC/TRR 227 “Ultra­fast spin dynam­ics” and is headed by Prof. Peter Oppen­eer, who is based at Uppsala Uni­versity, Sweden, and is one of the Mer­cator Fel­lows of the TRR 227. The suc­cess­ful can­did­ate is offered the pos­sib­il­ity to work in an excit­ing mod­ern research area in con­densed mat­ter phys­ics and will have oppor­tun­it­ies to inter­act and col­lab­or­ate with lead­ing exper­i­mental and the­or­et­ical groups in Ber­lin, Halle (Saale), Ger­many, and Uppsala, Sweden.


Mas­ter's degree (or Dip­lom) in Phys­ics, PhD degree in Phys­ics

(Pro­fes­sional) Exper­i­ence:
The applic­ant is fur­ther expec­ted to have excel­lent cap­ab­il­it­ies to per­form high-level research, as demon­strated through pub­lic­a­tions in peer-reviewed journ­als. Good com­mu­nic­a­tion skills both orally and in writ­ten Eng­lish, and also the abil­ity to work inde­pend­ently, are essen­tial.

The applic­ant is expec­ted to have a PhD degree in the­or­et­ical or com­pu­ta­tional phys­ics. A strong back­ground in the­or­et­ical con­densed mat­ter phys­ics is desir­able. Exper­i­ence with large- scale com­puter sim­u­la­tions is also desir­able, as well as the abil­ity to per­form com­puter code devel­op­ment.

How to apply:

For fur­ther inform­a­tion, please con­tact Mr. Prof. Dr. Peter Oppen­eer

Applic­a­tions should be sent by e-mail, together with sig­ni­fic­ant doc­u­ments, indic­at­ing the ref­er­ence code, in PDF format (prefer­ably as one doc­u­ment) no later than May 30th, 2022 to Mr. Prof. Dr. Mar­tin Weinelt: or postal to
