Helm­holtz-Zen­trum Dres­den-Ros­sen­dorf e.V.

Through cut­ting-edge research in the fields of ENERGY, HEALTH and MAT­TER, Helm­holtz-Zen­trum Dresden-Rossen­dorf (HZDR) solves some of the press­ing soci­etal and indus­trial chal­lenges of our time. Join our 1.500 employ­ees from more than 50 nations at one of our six research sites and help us mov­ing research to the next level!

The Cen­ter for Advanced Sys­tems Under­stand­ing (CASUS) is a Ger­man-Pol­ish research cen­ter for data-intens­ive digital sys­tems research. CASUS was foun­ded in 2019 in Görl­itz and con­ducts digital inter­dis­cip­lin­ary sys­tems research in vari­ous fields such as earth sys­tems research, sys­tems bio­logy and mater­i­als research.

The Young Invest­ig­ator Group Fron­ti­ers of Com­pu­ta­tional Quantum Many-body The­ory is look­ing for a

PostDoc (f/m/d) Devel­op­ment of time-depend­ent dens­ity func­tional the­ory sim­u­la­tions of warm dense mat­ter

within the ERC Start­ing Grant Pre­dict­ing the Extreme-PREX­TREME. The pos­i­tion will be avail­able at the earli­est pos­sible date. The employ­ment con­tract is lim­ited to two years.

Pro­ject goal:
You will develop new meth­ods for mod­el­ing dynamic prop­er­ties using time-depend­ent DFT cal­cu­la­tions within the lin­ear-response regime. As the first task, you will use exist­ing codes for the mod­el­ing of X-ray Thom­son scat­ter­ing (XRTS) exper­i­ments with warm dense mat­ter. This will give you new insights into the per­form­ance of dif­fer­ent mod­els for exchange-cor­rel­a­tion (XC) func­tion­als and XC ker­nels. Based on this, you will develop novel, improved mod­els, mak­ing use of our con­sid­er­able in-house expert­ise in top­ics such as state-of-the-art quantum Monte-Carlo sim­u­la­tions. A par­tic­u­lar focus of the pro­ject is on the sim­u­la­tion and ana­lysis of XRTS exper­i­ments in the ima­gin­ary-time domain [Nature Comm. 13, 7911 (2022)], which allows one to com­bine a num­ber of key advant­ages. A pos­sible cap­stone is the recon­struc­tion of elec­tron-elec­tron cor­rel­a­tion func­tions from DFT cal­cu­la­tions using novel dynamic XC ker­nels.

Working field:

  • Per­form time-depend­ent DFT cal­cu­la­tions of vari­ous mater­i­als (e.g., hydro­gen) at warm dense mat­ter con­di­tions
  • Invest­ig­ate exist­ing mod­els for XC func­tion­als, and sub­sequent devel­op­ment and imple­ment­a­tion of new mod­els in close col­lab­or­a­tion with QMC expert­ise from our group
  • Sim­u­late and ana­lyze XRTS exper­i­ments in the ima­gin­ary-time domain
  • Pub­lish in peer-reviewed sci­entific journ­als
  • Par­ti­cip­ate act­ively in sci­entific con­fer­ences

Requirements:

  • Excel­lent PhD in Phys­ics, Chem­istry or a com­par­able nat­ural sci­ence
  • Extens­ive expert­ise in the fields of math­em­at­ics, phys­ics, chem­istry or mater­ial sci­ence
  • Ambi­tion and a desire to push the fron­ti­ers of exist­ing meth­ods
  • Pro­gram­ming skills (e.g., in For­tran, Python, or C/C++)
  • Exper­i­ence in method devel­op­ment or use of quantum sim­u­la­tion pack­ages (e.g., VASP, Quantum Espresso, Elk)
  • Interest in mul­tidiscip­lin­ary col­lab­or­a­tion
  • Good com­mu­nic­a­tion skills in Eng­lish, in par­tic­u­lar, in a sci­entific con­text (e.g., at con­fer­ences, dis­cus­sions, and for writ­ing sci­entific pub­lic­a­tions)

What we offer:

  • A vibrant research com­munity in an open, diverse and inter­na­tional work envir­on­ment
  • Sci­entific excel­lence and extens­ive pro­fes­sional net­work­ing oppor­tun­it­ies
  • A wide range of qual­i­fic­a­tion oppor­tun­it­ies and indi­vidual career coun­sel­ing provided by the Postdoc Cen­ter HZDR-TUD
  • Salary and social bene­fits in accord­ance with the col­lect­ive agree­ment for the pub­lic sec­tor (TVöD-Bund) includ­ing 30 days of paid hol­i­day leave, com­pany pen­sion scheme (VBL)
  • We sup­port a good work-life bal­ance with the pos­sib­il­ity of part-time employ­ment, mobile work­ing and flex­ible work­ing hours
  • Numer­ous com­pany health man­age­ment offer­ings
  • Employee dis­counts with well-known pro­viders via the plat­form Cor­por­ate Bene­fits
